Abstract

Genetics has become the pre-eminent interpretation of the body and health and illness. This paper engages with a

central technique and metaphor of the new genetics—gene mapping. Through an exploration of the process of gene

mapping, the paper argues that the genetic material of the body is spatialised and transformed into a knowable and

manipulable entity. Three interpretations of this spatial transformation of the body’s materiality are discussed, in turn

drawing on Foucault’s notion of the construction of medical knowledge, the deconstruction of geographical maps and

Haraway’s ‘fetishised’ conception of the gene map. The paper concludes by considering contestations to this dominant

discourse, and begins to construct an alternative spatialisation of the body that attempts to ‘place’ the gene more

appropriately in a socially-embedded body and health.

Introduction

Genetics has become the pre-eminent interpretation,

and the gene the prime signifier, of the human body and

health and illness. This dominant ‘genocentric’ discourse

is producing an embedded knowledge of direct and

deterministic relationships between genes and an ever-

widening spectrum of physiological and psychological

conditions (Lippman, 1992). The notion of ‘the gene for’

now sits firmly within clinical and popular health

discourses and the gene’s ‘iconic’ status has extended

beyond health to matters of individual and social

behaviour (Nelkin and Lindee, 1995).

The ‘new’ genetic knowledge is embedded within and

extends the biomedical interpretation of health and the

body, and continues the narrowing and penetration of

the medical gaze into the body. It reproduces the key

elements of the biomedical understanding: the specific

location of disease and treatment in the body’s internal

geography, the conceptual model of the body as a

machine of individual parts with distinct roles, and the

notion of the body as an entity determined by its internal

environment (Conrad, 1999). Importantly, though, the

biomedical discourse is also extended with the produc-

tion of genetic knowledge—the sense of direct relation

between gene and disease has produced two (opposing)

responses, firstly, a ‘fatalism’ of genetically ‘caused’, and

therefore unassailable, illness and disease (Seniora et al.,

1999) and, secondly, a sense of hope/confidence that

genetic knowledge may/will produce direct genetic

solutions to these seemingly direct genetic problems.

As Rose and Rose observe, the new genetic ‘discoveries’

seem to ‘‘offer to eliminate illness, prolong life, grant our

children enhanced intelligence and better looks—a

cornucopia of technological goodies undreamed of even

in the science fiction of prior generations’’ (Rose and

Rose, 2001, p. 4). The claims of a ‘revolution’ in body

knowledge and disease diagnosis and treatment, claims

that receive regular coverage in the media are, as with all

such claims of final and complete knowledge, overstated

(Foucault, 1973). However, whatever the material health

and medical benefits, and whatever the issues inherent in

holding such knowledge, the new genetics has gained a

powerful hold on the bodily imagination (of the West)

and has challenged many long-standing claims of social*Tel.: +44-1382-348276; fax: +44-1382-344434.

construction of gender, race and age, in addition to

health and illness.

The body, as a site of representation, as a socially-

embedded and constructed entity, and as a source of

meaning and identity, is now an established sub-field of

research within human geography (Bell and Valentine,

1995; Pile and Thrift, 1995; Longhurst, 1995; Hall,

1999). Within the geography of health, there has been

limited and reluctant use of the theoretical debate on the

body—Kearns (1995), Parr (1998), Hall (2000) and

Moss and Dyck (2001) are exceptions, noting the messy

complexity of bodies and their corporeal reality. Hall

(2000) goes further, calling for an engagement with

biology in its recognition of the centrality of the

organism—including the human body—to life. The

nervousness of many health geographers in including

the body and biology is rooted in the long-standing

theoretical and political rejection of biological determin-

ism and the recognition of the explanatory power of

social constructionist accounts of health, underpinned

by an epistemological and methodological distancing of

human geographers from the natural sciences (Massey,

1999a).

The new genetics presents both a renewed difficulty

and a potential opportunity for geography to engage

with matters of the body and biology, and to traverse

seemingly impossible theoretical and disciplinary gulfs.

Whatmore (1999, p. 259) comments that, ‘‘Given

geography’s claim to ‘span’ or ‘integrate’ the natural

and the social sciences, our relative silence on questions

of biotechnology, and their social and environmental

implications is, to say the least, peculiar’’, when, she

argues, ‘‘These questions are, in themselves, amongst the

most vital confronting technical, social and ethical

agendas for the coming century’’ (Whatmore, 1999).

Whatmore suggests an answer to her own question of

what geography’s place could be in the life science era,

by proposing a geography that ‘takes life seriously’

through an exploration of the spaces ‘‘teeming with the

stuff of which all our futures will be made’’ (Whatmore,

1999, p. 260). Castree (1999, p. 764) claims that the

issues of nature—social relations that genetic develop-

ments raise places it firmly within the geographical realm

of inquiry. A critical engagement that draws on long-

standing synthetical practices within geography is

possible and, Castree argues, necessary if, ‘‘geography

wishes to establish its relevance to our present and

future world’’. The theoretical and methodological

realities do not as yet equal the desire of this

engagement, but a rejuvenated biogeography is posi-

tioning itself as the focus for geographical interpretation

of the new genetics, biotechnology, and other geogra-

phies that transgress the nature-society boundary, such

as cities (Hinchliffe, 1999). An engagement with biology

and with the science and practice of biotechnology can,

in very many ways, draw on, and add to, the current

conceptual concerns of biogeography: recognition of the

complexity of natural systems, the flows and networks

operating in the interactions between internal and

external environments, and the proper ‘placing of life’

in the scheme of things (Spencer and Whatmore, 2001,

p. 140). A full day session at the RGS–IBG Annual

Conference 2002 entitled ‘Genetic Geographies’ was an

early conflation of this; through a particular engage-

ment, this paper is a preliminary offering.

The paper takes the object of the ‘gene map’ and the

practice of ‘gene mapping’ as a prime site and process of

the genetic interpretation of the body and health and,

simultaneously, as a notable signifier of the new genetics

era. Gene maps represent the relative and absolute

positions of genetic sequences on the 23 pairs of

chromosomes that sit within the nucleus of almost every

cell in the human body. The representation of this

apparent ‘geography of the genes’ is central to the

construction of knowledge about the ‘(mal)function’ of

genes and their relation to bodily (mal)function. Maps

too remain the prime signifier of the geographical

discipline, surviving the critical ravages of postmodern

and cultural ‘turns’ by making the transition from a

presentation of claimed actuality to a mode of meta-

phor, while maintaining their representational and

explanatory claim.1 The use of the term and the

apparent adoption of the process within genetics

demands our attention. This paper explores the making

and meaning of maps of the genes, and considers ways

of interpreting their representation of the spatiality of

the body, and of health and illness.

The paper is in two main sections: first, the object of

the gene map and the process of gene mapping are

explained and the nature of their spatiality and

interpretation explored; second, three possible interpre-

tations of the spatiality of the gene map are set out; in

conclusion, an alternative spatialisation is developed,

one that attempts to ‘place’ the gene more appropriately

in the body and in discourses of health and illness.

Mapping the genes

The gene map is the central analytical tool of the new

genetic knowledge. It operates both as an information

‘pool’ in the gathering of data and as a framework for

the subsequent interpretation of genetic information and

the linking to conditions of health and illness. The

1This counters to some degree Martin’s (2000, p. 5) claim

that maps ‘‘continue to recede from our geographical imagina-

tion’’. There are two reasons for this: firstly, as Martin

concedes, developments in mapping continue apace in the field

of GIS and, secondly, the map and mapping play a central, if

not literal, role in the conceptualisation of space and spatial

relations (see Pile and Thrift, 1995).

importance of the technical and conceptual role of the

gene map is that it ‘‘provides the only connection

between biological reality and the underlying genome. In

many cases, without genetic maps nothing else would

followy Detailed maps provide the only means by

which the genes that contribute to disease susceptibility

can be identified and ultimately characterised’’ (Sudb-

ery, 1998, p. 54–55). It is the key operational tool and

metaphor, ‘making sense’ of the materiality and provid-

ing the means for further analysis and application. As

such, genetic maps share some of the key characteristics

of orthodox geographical maps, as will be further

discussed in the second section of the paper. However,

it is important to establish at this point that genetic

maps are of quite a different format to what we usually

understand as maps: genetic ‘maps’ consist of series of

positional codings of genetic sequences along the

chromosome, with no graphical expression of these

‘co-ordinates’.

The paper argues that in the process of gene mapping

the genetic material of the body is structured, organised

and spatialised. A gene map’s ability to ‘make sense’ of

the ‘genomic landscape’ is founded on this transforma-

tion of biological materiality into spatial information,

By making something spatial it can be known,

interpreted and ultimately controlled or manipulated

(Massey, 1999b, c).

There are three main forms of gene maps—linkage,

physical and expression—each telling a particular

spatial story about the genes and the body and

together forming a powerful spatialised ‘body of knowl-

edge’ of the human genome. It is to these that we

now turn.

Linkage maps

Linkage or genetic maps represent the relative

positions of individual genes along the chromosome.

They are constructed through the study of the frequency

of associated inheritance (known as ‘recombination

frequencies’) of certain characteristics at reproduction.

The characteristics may be physical features (pheno-

types), such as disease, or they may be features of the

gene sequence (genotype). These characteristics combine

freely across chromosomes at the moment of reproduc-

tion, except, as is often the case, when they are on the

same area of the chromosome. Closely positioned genes

are often inherited together and so the associated

characteristics appear linked as well. The relative

position of genes can therefore be represented by the

frequency of recombination—the greater the frequency,

the stronger the linkage and the closer the genes on the

chromosome. This process continues iteratively until the

‘positions’ of gene sequences can be determined (Dib

et al., 1996). The characteristics selected are known as

‘genetic markers’ as they provide fixed points of

reference against which to compare other genetic

material and, more importantly here, as ‘landmarks’ to

locate another gene, for example one apparently

connected to a particular health or illness condition,

through the level of recombination frequency between

the gene and the genetic marker. To achieve compre-

hensive and ‘accurate’ linkage maps, three significant

methodological manoeuvres are undertaken: firstly,

biological samples from a set of Mormon (Utah, USA)

and Venezuelan families are used by the ‘Centre d’Etude

Polymorphism Humain’ (CEPH) bio-technical research

institute in Paris, France, to construct the reference

genetic markers of the so-called ‘pedigree’ inheritance;

secondly, a mathematical technique—Log Ratio of

Odds or LOD—is used to calculate the ‘likelihood’ of

linked inheritance; thirdly, to increase the number of

genetic markers and so the coverage of the linkage map,

new markers, based not on phenotypic characteristics

(which are too few in number), but instead on

differences in sequences in parts of the DNA between

individuals, are made.

Through chemical and genealogical analysis at the

genetic and familial scales, respectively, a ‘comprehen-

sive’ linkage gene map has been produced (Dib et al.,

1996). The story it tells is one of relationships between

particular genetic elements of the chromosomes and

between the genes and chromosomes and the character-

istics of the body (between the genotype and the

phenotype). Indeed, a direct relationship between the

genotype and the phenotype is the central initial

assumption of the linkage map (Curran, 1997). In the

process of this mapping, the notion of genetics as solely

one of inheritance, that is, as a story of chronology and

genealogy, has been transformed into a story of

relational spatiality. The linkage map makes the relative

spatial positions of genetic sequences along the chromo-

some matter to the operation of the genes and their

effects on the body. Importantly, this transformation is

one that has had to have been made, through a

transformation of the genetic material itself. To transfer

the story of inheritance to the story of genetic relational

spatiality, the genetic material has had to be reimagined

as spatialised. The methodological manoeuvres neces-

sary to achieve this transformation reveal its produced

nature as they involve, respectively, the ‘folding in’ to

the map of the ‘average’ human genome of genealogical

information from ‘ideal’ families, mathematical exten-

sions of genetic activity, and the creation of landmark

features by the chemical manipulation of the gene

sequence. The internal spatialising of the genetic

sequences and the production of a framework of gene

location also makes it possible for the connection

between genotype and phenotype to be concretised—if

the (relative) location of a gene sequence is determined,

then it’s ‘causative relationship’ to a bodily character-

istic can be more easily ‘pinned down’.

Page 4: Reading maps of the genes: interpreting the spatiality of genetic knowledge

Linkage maps involve a spatial transformation that

objectifies the genetic material, an essential process in

the production of knowledge of the genes (Hinchliffe,

2001; Rheinberger, 1997). And once something has been

spatialised (and mapped) there is no going back.

Physical maps

Linkage maps spatialise the genome, and in doing so

produce a ‘framework’ of a landscape to be mapped in

greater detail. Physical maps of the genes represent the

‘actual’ or ‘precise’, as opposed to relative, locations of

gene DNA sequences along the chromosome. The

principal purpose of physical gene maps is the identifica-

tion of a gene sequence and the subsequent listing of the

‘base pairs’ that make up the sequence.2 As they

‘‘provide the scaffold upon which the sequence [is]

assembled’’ (Dennis et al., 2001, p. 813), they are the key

objects in the overall mapping process. As with linkage

maps a number of methodological techniques have been

devised to ‘locate’ the gene sequences ‘precisely’ on the

chromosome. The principal method makes many copies

of the DNA sequence where the particular gene is

thought to lie—identified by the linkage map—and

‘overlaps’ these copies. By overlapping the copies or

‘clones’ the known sequences (drawn from the genetic

markers of the linkage map) can be matched or aligned

and the parts that do not match identified. It is at these

places where the genetic material does not correspond

that the physical location of the sought gene is stated to

be (Stewart and Cox, 1997). An alternative method—

‘Radiation Hybrid’ mapping—determines the position

of gene sequences through assessing how known genetic

markers maintain their relative positions when genetic

material is irradiated (Leach and O’Connell, 1997).

Physical maps make the spatial ‘claim’ of representing

the ‘‘actual location of DNA sequences [genes] in the

genome’’ (Sudbery, 1998, p. 69, emphasis added),

reinforcing this claim through the assignment of codes

of location. Unpacking the making of physical maps,

primarily through the ‘clone’ method, reframes this

claim somewhat—clone maps determine gene sequence

location through an iterative method of deduction

through comparison of known locations, which them-

selves are based on markers produced through linkage

mapping. The ‘actual’ location becomes a ‘calculated’

position, the code of the gene sequence location a code

of relative position. Radiation Hybrid mapping, which

claims ‘greater accuracy’ than the clone technique,

produces only a ‘confidence’ of certainty (Stewart and

Cox, 1997, p. 91). The ‘precise’ physical map of the

genes loses its sheen, and becomes a set of estimates,

claims, approximations and predictions of the constitu-

tion of genetic material along the chromosome (Stewart

and Cox, 1997, p. 74; Bork and Copley, 2001).

This, importantly, is not arguing that physical genetic

maps are inaccurate or lack technical rigour, rather that

their claim to ‘accuracy’ is one that reflects their

fundamental assumption and their purpose. There is a

deeply embedded assumption of a physical nature that

pre-exists society and science. The consequence of this is

that over time this natural ‘reality’ will become known in

totality (Hinchliffe, 2001). This assumption produces the

purpose of physical gene maps, i.e. to accurately locate

the components of the genome and, further, this is

understood as an achievable goal. The importance,

therefore, of physical maps is their claim, rather than

their actuality. Their claim is one of accuracy, precise-

ness and, crucially, of the ability to know, intimately and

ultimately, a spatial area. Uncertainty of knowledge,

and the intrusion of other natural-social influences into

the space of the genome, is something to be eliminated

rather than embraced (Hinchliffe, 2001).

Expression maps

The third type of genetic map and perhaps, in the

context of the underlying drive of the new genetics to

tackle issues of health and illness, the most crucial, is the

expression map (Schuler et al., 1996). As has been noted,

not all genetic sequence material or DNA is connected

to the action of proteins in the cells of the body (and

hence, the claim goes, to the process of physiological

and psychological conditions). Expression maps limit

their interest and coverage to the action or ‘expression’

of gene sequences or, more precisely, to the presence of

mRNA (messenger RiboNucleic Acid), the chemical

‘link’ between a gene sequence and the change/action of

a protein.

Expression maps make the connection between the

spatiality of the genetic material and the ‘activity’ or

effect of this material in the body. This connection

marks the key claim of the new genetics, the direct and

causal relationship between genetic and bodily materi-

ality, a claim that is keenly disputed on two grounds,

firstly, that genes only operate as part of a larger

biological system (Fox Keller, 1994) and, secondly, that

equating ‘fine-grained’ genetic information with ‘coarse-

grained’ bodily disease information is conceptually and

practically problematic (Lloyd, 1994). More precisely,

the claim is based on the spatialising of the genetic

materiality—it matters for their effect where genes are

said to be located—and its consequent spatialising of the

(mal) functioning of the body. Without the construction

of their spatial ordering, genetic material could not be

understood as having a direct and causal effect on the

body. Expression maps make the claim that space

2 ‘Base pairs’ are the chemical elements of DNA, so-named

because they are arranged in a sequence of repeating pairs. The

four chemicals that compose the two pairs are adenine (A) and

thymine (T), and guanine (G) and cytosine (C).

matters, space is made and the nature of its making has

an impact on our understanding of the very object it

seeks to represent (Massey, 1995).

A map of the human genome

The production of a ‘complete’ gene map of the

human genome required the alignment of the three types

of genetic maps, using the common reference point of a

set of genetic markers (Hudson et al., 1995). The

integration of these maps required two further align-

ments, one theoretical and the other institutional-

political. Theoretically, the spatialised understanding of

genetic material developed through the gene mapping

process involved three distinct episodes, the production

of a spatial framework (in linkage maps), the detailed

locating of genetic material within the framework (in

physical maps) and the connecting of genetic material

and the characteristics of the body (in expression maps).

To produce the genomic map these three episodes or

‘conceptual techniques’ (Rabinow, 1996, p. 4) have to be

joined together into a complete story—the map of the

human genome encapsulates a progressive and deepen-

ing spatialisation of the genes and the body. Institution-

ally-politically, the making of the map of the human

genome has required the alignment of scientific,

economic, cultural, industrial and political organisations

and interests, operationalised through the ‘Human

Genome Project’. Such has been the prescribed task of

mapping and sequencing all of the genetic material of

the human genome that an international consortium of

biotechnical laboratories have undertaken different

aspects of the task. This collaboration has been financed

and organised by national governments, supported by

political leaders and involved extensive collaborations

with biotechnological and pharmaceutical companies.

The Human Genome Project, begun in the late 1980s

in the USA and funded initially by the US Department

of Energy3 and later by the National Institutes of

Health, has become an international network of 20

laboratories4 (Baltimore, 2001) funded by governments

and charities, and the whole process of this ‘big science’

maintained and sustained by repeated governmental,

medical and scientific claims that it is a scientific

‘endeavour’ that will produce significant health and

medical benefits for global society (Cranor, 1994). The

stated ‘goals’ for the ‘completion’ of the Human

Genome Project (Collins and Galas, 1993) included a

‘complete’ linkage map, a complete physical map, the

identification of genes through expression maps and the

sequencing or listing of all the human DNA.5 An-

nouncements of ‘completion’ have been made across the

time span of the project—the complete linkage map in

1995 (Sudbery, 1998), the physical map in 2000

(International Human Genome Mapping Consortium,

2001a), the increasing number of diseases ‘linked’ to

specific genes (International Human Genome Mapping

Consortium, 2001b)—most significantly, in terms of the

new genetics place in health and political discourse, the

announcements of the ‘draft’ and ‘complete’ sequence of

the ‘base pair’ chemical components of the human

genome, in June 2000 (Guardian, 2000; Independent,

2000) and February 2001 (Guardian, 2001), respectively.

These ‘achievements’, likened to the moon landing and

‘splitting the atom’ (Guardian, 2000), have been a

necessary part of the story of the Human Genome

Project, a series of ‘end points’ to a singular, definite

exercise. While most geneticists always knew and

emphasised that the nature of the genome and the body

is such that a study of it will never be complete, the

mapping and sequencing had to have an end to maintain

the alignment of financial, political, medical, bioindus-

trial and public support and interest (Judson, 2001).

Rabinow (1999) has described the French element of

the Human Genome Project as an ‘assemblage’ of

interests, public and private, material and conceptual,

medical and emotional, financial and political, that

‘come together’ in a network, but always under internal

and external pressures. Hinchliffe (2001) notes how the

process of scientific policy-making and practice is often

imagined as a benign process of reaching a clear and

achievable end goal, with conflicts, power relations and

contested imaginations marginalised. The alignment of

the diverse interests in the Human Genome Project is

commonly represented as such an exercise, united by a

common purpose. There is a very particular reason for

this: for the map of the genome to be completed, a high

degree of certainty was necessary about achieving the

goal—to secure continued funding, to maintain the

consortium of diverse parties, and to make the claim of

‘total’ knowledge possible. The mapping of the human

genome is indeed a remarkable achievement, but

perhaps for quite different reasons to the ones com-

monly cited.

3The US Department of Energy has a long-standing research

interest in radiation-caused genetic mutation through its

nuclear energy and weapons programme (Wilkie, 1994).4For example, in the UK, the Sanger Centre funded by the

Wellcome Trust and the Medical Research Council and, in

France, CEPH, funded by the French Government and the

‘Genethon’ laboratory funded by the Muscular Dystrophy

Association (Rabinow, 1999).

5Other goals of the Human Genome Project included:

technology development (e.g. automatic data collection), model

organisms (simpler organisms, e.g. the mouse and bread yeast,

are used to inform human genome investigations), informatics

(accelerated processing and analysis of genetic information),

ethical, legal and social issues, training, technology transfer and

outreach (Collins and Galas, 1993).

Page 6: Reading maps of the genes: interpreting the spatiality of genetic knowledge

With the completion of the mapping and sequencing

process, the assemblage of interests has begun to

fracture, primarily over the issue of the ownership of

and access to the genetic data. The commercial

significance of genetic information has produced con-

cerns over the ‘patenting’ and exploitation of human

genetic data (Castree, 2001). Just as orthodox geogra-

phical mapping ‘produces’ territorial space for exploita-

tion, so genetic mapping transforms genetic material

into a space ripe for commercialisation; this is explored

in more detail in the second section of the paper.

Interpreting maps of the genes

The gene map is the inner picture of the species. It’s

immortal part. The gene map may tell us not just

where the genes are, but why they are there (Ajl,

1979, quoted in Wilkie, 1994, p. 86).

Gene mapping is a process of ‘making spatial sense’ of

the chemical material that constitutes the chromosomes

and which is linked to protein activity. In making

linkage, physical and expression maps, a structured and

detailed progressive spatialisation is made of the body.

This in turn transforms the body into a bounded space,

as a framework must have a limitation, and hence into a

potentially knowable space. Put another way, gene maps

arguably have a dual (but linked) purpose, one of which

could not exist without the other: firstly, to ‘discover’ the

relative and ‘actual’ location of genetic sequences and,

secondly, to make it possible to understand genetic

material in this manner. In this section, three possible

interpretations of this spatialisation of genetic material

and genetic knowledge will be discussed, but first some

consideration is given to the dominant interpretation of

the organisation of genetic knowledge.

The announcement of the ‘completion’ of the ‘first

draft’ of the full sequence of the human genome in June

2000 was accompanied by a plethora of metaphors, most

notably concerning language and written knowledge.

The base pairs of DNA were likened to ‘letters’, the

genes to words, and the genome to the ‘Book of Life’

(Independent, 2000; Ridley, 1999; Kay, 1999). This

(Christian) religious twist was amplified by US President

Clinton’s phrase describing the process of the Human

Genome Project, ‘‘We are learning the language in

which God created life’’ (Independent, 2000, p. 1). The

media and politicians were drawing on a longstanding

metaphor for genetic knowledge discovery. For exam-

ple, Wilkie (1994) has likened the assemblage of genetic

knowledge within the body through genetic mapping

and sequencing to the collective of knowledge contained

within a library, and the purpose of the Human Genome

Project to ‘gather’ this information,

It is as if those engaged upon the Human Genome

Project have wandered into a vast library, with the

genes corresponding to the books, intent on reading

every word (1994, p. 41).

Wilkie further likens the 23 pairs of chromosomes to

the shelves on which the genes/books are located, and

the mapping of the genes as a, ‘‘process of building up

an index or catalogue of the genes’’ (Wilkie, 1994). The

metaphor of the library embodying the sense of an

existing, finite set of legitimated knowledge contained in

the books/genes on the shelves/chromosomes sits

comfortably within the discourse of the gene as the

‘ultimate’ and reducible knowledge of the body—with

the chromosome, cell and organism playing the ‘hosting’

role—a knowledge that, if we read/experiment for long

enough (and it is assumed we have the ability do so) will

reveal itself in totality. The linkage and physical gene

maps in the library metaphor have distinct roles: a

linkage map is likened to the author index, where all the

references to books are in order but without details of

location; the physical map indicates the specific ‘shelf’

location of the book. This metaphor seems to confirm

the role of gene maps as indexes and wayfinders, as

frameworks for the understanding of the spatial

structure and contents of the genome. The library

metaphor has a further important consequence. If we

return to the phrase, ‘‘It is as if those engaged on the

Human Genome Project had wandered into a vast

library’’ (Wilkie, 1994, p. 41, emphasis added), the

imagining of the chromosomes and genes (and organism)

as a pre-existing spatial knowledge waiting to be

‘discovered’, establishes both the purpose—to ‘read

every word of every book’—and the method—‘to build

up an index or catalogue’—of gene mapping and

sequencing. The biological materiality becomes the

spatialised knowledge and, in the crucial turn, the

tightly defined, solely internal, assemblage of linked

relations, physical locations and expressions becomes

the reality of the genes, chromosomes and body.

The library metaphor of structured and finite (and

knowable) genetic material is dominant in popular and

scientific discourse on the new genetics, a metaphor, this

paper is arguing, that masks the complex nature of the

genes, both conceptually and practically, and the

method and purpose of gene mapping, i.e. the spatialised

transformation of the genes. At this point, the paper sets

out three possible interpretations of the spatialising of

genetic materiality in gene mapping.

A new spatialisation of the body

Foucault’s ‘archaeology’ of medical knowledge in

‘The Birth of the Clinic’ (1973) unearths the construc-

tion, through institutional (clinics) and discursive (the

medical ‘gaze’ and the opening of corpses) practices, of a

E. Hall / Health & Place 9 (2003) 151–161156

Page 7: Reading maps of the genes: interpreting the spatiality of genetic knowledge

new ‘truth’ of the body and health and illness. More

specifically, the study is concerned with spatialised

transformations of knowledge of the body in two

particular historical periods. The three ‘spatialisations’

identified by Foucault—primary, secondary and ter-

tiary—each involved a particular (re)imagining of the

body and the relationship between the elements of the

body and disease and illness.6 The paper argues that the

transformation and spatialisation of genetic material

and knowledge involved in gene mapping has reso-

nances of all three spatialisations and presents possibi-

lities for our understanding of the new genetic

knowledge.

The ‘primary spatialisation’ or ‘configuration’ of

disease describes the classification of disease and the

body in the 17th and 18th centuries, and the building up

of medical knowledge through the construction of

tables, known as ‘nosologies’. In the spatialisation the

tables of the organisation of disease became the material

form of the disease itself, ‘‘the classificatory ruley

appears as the immanent logic of morbid forms, the

principle of their decipherment, and the semantic rule of

their definition’’ (Foucault, 1973, p. 4). Such a

transformation of materiality is evident in gene maps,

as biological material is structured and ordered—

spatialised—in order to be known and in turn this

structure ‘turns back’ into the body as the genetic

material is then open to transformation itself. The

‘secondary spatialisation’ or ‘localisation’ of disease in

the late 18th and early 19th centuries imagined the ‘deep

spaces’ (Foucault, 1973, p. 5) of the body as a

‘geography’ of disease, where each condition had a

specific location, and which were represented by detailed

anatomical drawings and atlases, ‘‘Disease is no longer a

bundle of characters disseminated here and there over

the surface of the body y it is a set of forms and

deformationsy brought together in sequence according

to a geography’’ (Foucault, 1973, p. 136). The linking of

physiological conditions to precise bodily locations has

taken a further, and more bodily penetrating, step with

gene mapping. The connecting of bodily (mal)function

to particular parts of the genetic sequence produces a

new geography of disease in the body that shares the

Foucauldian sense of direct causal relationship. Fou-

cault’s ‘tertiary spatialisation’ describes the institutions,

language and practice by which, ‘‘a disease is circum-

scribed, medically invested, isolated, divided up into

closed privileged regions, or distributed throughout care

centres’’ (1973, p. 16). Gene mapping is a process of

temporary assemblages of such institutions, primarily

biotechnical laboratories, clinical medical research sites

and pharmaceutical companies (Rabinow, 1999) as the

body’s genetic material is penetrated across the global

field.

Importantly, Foucault’s analysis critiques the produc-

tion of this medicalised information, noting in particular

the role of the wider body and social spaces, seemingly

outwith the realm of the medical (and genetic) body. In

the primary spatialisation, Foucault argued that there

was an unspoken recognition of the complex body

beyond the classification; in the secondary, the locating

of disease to particular parts of the body did not imply a

set of isolated organs, rather the body was clearly an

interconnected ‘organic space’; and in the tertiary,

Foucault recognises the broader ‘social space’ within

which this production of knowledge occurs, the ‘‘poli-

tical struggles, demands and utopias, economic con-

straints and social confrontations’’ and the possibility of

contesting dominant medical knowledges (Philo, 2000,

pp. 13–16).

Foucault’s notion of successive body knowledges

shows clearly how spatialised transformations are

transformations of knowledge and of the body through

scientific, medical and institutional practices. It also

shows how these transformations do not necessarily

deny the broader bodily and social contexts, however

much they are changed. Gene mapping does produce a

new spatialisation of the body and health and illness,

and this transformation does produce material changes

in the body, but there are gaps and spaces within which

the organic, interconnected, dynamic body can be

glimpsed.

Deconstructing maps of the genes

The use of the term ‘map’ and the process of

‘mapping’ in the science of genetics demands our

attention as geographers, particularly so because geneti-

cists themselves are drawing on geographical notions of

mapping. Jones (1994, p. 56), likening the process of

genetic ‘discovery’ to the cartographic explorations of

the British Empire, claims that ‘‘Genetics, like geogra-

phy, is about maps; in this case, the inherited map of

ourselves’’ and compares the making of the physical

map of the genome to ‘‘surveying a country with a six-

inch ruler, starting at one end and driving doggedly on

to the opposite frontier’’ (p. 67). The metaphor is

powerful: the genome as a bounded territory and the

gene map as an accurate representation of this territory.

While genetic maps are quite different in format to

orthodox maps of land territory, the usage of mapping

terms, and more importantly the metaphors, by

geneticists and the scientific media, with full knowledge

of the deeply embedded understanding of the purpose of

maps and their central role in society (Dorling and

Fairbairn, 1997), means that as geographers we can and

must treat gene maps and mapping to a rigorous

analysis (something that I can only begin here).

6 I wish to acknowledge Philo’s (2000) excellent analysis of

‘The Birth of the Clinic’ (1973).

Page 8: Reading maps of the genes: interpreting the spatiality of genetic knowledge

Wood (1993) develops a comprehensive deconstruc-

tion of the purpose and method of maps. He argues that

the traditional understanding of the map as a ‘mirror of

reality’ (Pickles, 1992), or a ‘window on the world’

(Harley, 1988, 1992), is deeply embedded in (Western)

society, an outcome of the role of the map in colonial

expansion and the division and ownership of land

(Massey, 1995; Harvey, 1989). Maps are understood as

‘spatial data handling tools’ (Dorling and Fairbairn,

1997, p. 1), instruments of practical application and, as

such, objective entities representing a knowable and

certain landscape. Wood’s contribution is to disrupt

this, and to recognise the ‘power of maps’: the

representation of what cannot be encompassed in the

field of vision (Harvey, 1989),7 the embodiment of

knowledge in the map, the desires for a particular future

reality, and the socio-cultural-technical context within

which it was made (Haraway, 1997). As Wood states,

‘‘knowledge of the map is knowledge of the world from

which it emerges y an isomorphic counter-image to

everything in society that conspires to produce it’’ (p.

18). Reading maps, then, takes on quite a different

meaning, as route finding is replaced by textual analysis,

‘‘Our task is to search for the social forces that have

structured cartography and to locate the presence of

power—and its effects—in all map knowledge’’ (Harley,

1988, p. 232).

If we accept further, firstly, that maps are ‘totalising

devices’ (de Certeau, 1984), that provide the ability to

imagine the world from outside without having seen it,

to make it stable and certain and knowable (Harvey,

1989) and, secondly, that maps are ‘producers of space’

(Lefebrve, 1974), then gene maps require a quite

different analysis. One of the central arguments of this

paper is that space has to be made, and that once

spatialised an entity is transformed and transformable.

Territorial maps and gene maps are a key instrument in

this transformation. When a map is described as a

‘spatial data handling tool’ it is just that, but in quite a

different sense to that intended by cartographers. The

map is not a mirror of reality, a window on the world,

but is that reality, is that world. The purpose of the gene

map is to imagine the gene, to transform its chemical

materiality into a set of individual objects set within an

overall spatial structure—the chromosome, the cell, and

the body. The maps make sense of the gene, indeed they

make the gene. Gene maps are perhaps the most

important part of the process securing the gene and

genetics as the prime interpretations of the body and

health and illness. The gene map makes the body a

genetic body through the power of perspectivism—gene

maps can see ‘beyond’ the visible and beyond the

possible: ‘‘This is the very point of the map, to present us

not with the world we can see, but to point toward a

world we might know’’ (Wood, 1993, p. 12). A key

process of the gene map, as with the landscape map, in

its making of spatial knowledge and its ordering of the

space, is the transformation of the natural into the

conceptual and in doing so its breaking down into

individual objects, ‘‘To map a river is to bring it into

being—inescapably—the land that it drains; what was

originally whole is suddenly in pieces—water, banks,

slopes, hills—which as they materialise take their places

(if only vis-"a-vis each other)’’ (Rundstrom, 1993, p. 162).

Lefebvre (1974) calls this transformation the ‘pulverisa-

tion’ or fragmentation of the landscape body, the

atomising of the body into separate parts that make

sense in the individualism of the capitalist economy.

Through this transformation, spatialisation and frag-

mentation of the body through gene mapping into a

genetic, atomised body, the power of the body is also

changed (Foucault, 1980), from a whole power to a

fragmented power, opening up the body and the genes to

domination and ownership (Harvey, 1989). The patent-

ing and commodification of genetic information by

pharmaceutical and biotechnology companies is the

first step in this process (Castree, 2001; Spencer and

Whatmore, 2001).

‘Fetishising’ the gene

Haraway (1997) employs the term ‘reification’ to

describe gene mapping in order to capture the conver-

sion of an idea or concept into an object, the process of

materialisation. More specifically, reification ‘‘trans-

mutes material, contingent, human and nonhuman

liveliness into maps of life itself and then mistakes the

map and its reified entities for the bumptious, nonliteral

world’’ (1997, p. 135, emphasis added). She takes the

phrase ‘life itself’ from the writing of Franklin (1993),

who describes how ‘life’ and nature—in its broadest

sense—becomes transformed into particular forms of

materiality and ‘instruments’, i.e. these instruments

become ‘life’ (itself). The gene map is a primary example,

Haraway argues, of this, as it is both tool/instrument

and signifier. It is this transfer of life into map and back

again, this transformation of material biology into

genetic signification and then back again into the body

through the application of the representation, that lies at

the heart of Haraway’s concern.

Further, she describes gene mapping as a ‘‘particular

kind of spatialisation’’ (1997, p. 141), which she refers to

as ‘corporealisation’. She envisages this spatialisation of

the body as being the network of interactions between

human and nonhuman actors operating within the

context of ‘technoscience’ and producing ‘natural-

technical’ material objects of the body, such as cells,

molecules and genes. The gene map is the process that

7Harvey (1989) notes the central importance of ‘perspecti-

vism’, the movement of the eye of the mapper from the ground

in amongst the materiality to an elevated and distant position.

E. Hall / Health & Place 9 (2003) 151–161158

Page 9: Reading maps of the genes: interpreting the spatiality of genetic knowledge

makes this happen, makes it possible, because it draws

together and makes real the concepts of the body and

genetics. Out of this interpretation has emerged a

fixed entity of the gene and, in Haraway’s argument,

it is a gene that is ‘fetishised’, i.e. that is imagined as

possessing power and at the same moment accepted

as simply physical. In the heady rush that is fetishism

the rest of the body, both its bodily materiality and its

social embeddedness, is blanked from the field of

conception.

Conclusion: ‘putting the gene in its place’

An interpretation of gene maps and mapping is just

one possible engagement for geography to make with

the ‘new’ genetics, but it is, this paper has argued, a most

crucial one. Gene maps are the central technical and

conceptual ‘tool’ in the ‘exploration’ of genetic material,

transforming this particular biology of the body into a

structured, ordered and spatialised entity and knowl-

edge. And it is this process of spatialisation that makes

the new genetics knowledge possible and in turn makes

possible the manipulations, both medical and commer-

cial, of the body’s matter.

Within this central argument, the paper has made

three other key points. Firstly, the very process of gene

map production must be (re)interpreted as one of claims,

uncertainties, errors and what the paper termed

‘methodological manoeuvres’, all familiar features in

the field of science (Latour, 1987), but often missed in

the glare of statements of ‘accuracy’ and ‘completeness’.

In addition, the social, economic, technical and political

‘assemblages’ within which gene mapping occurs are

shot through with interests, conflicts, contestations and

indecisions that are marginalised, even obscured, in the

claims of achievement (Hinchliffe, 2001). An effective

‘teasing out’ of these missing narratives is clearly a key

challenge.

Secondly, as Lippman (1992) argues, for gene map-

ping to take place requires more than the availability of

equipment and techniques, it requires the understanding

that such knowledge is there to be gathered. A powerful

sense of a pre-existing ‘natural’ body, its genes and

chromosomes organised as within the bounds of a

library, pervades the process of gene mapping. In their

making gene maps reproduce this conception of the

body and frame the subsequent exploration of genetic

material, and connections to health and illness.

Thirdly, gene maps (inevitably) objectify and privilege

the gene within the body’s biology and its role in the

development of physiological characteristics. But more

than this, the power of the (gene) map is such that this

‘claim’ becomes a conceptual and material ‘truth’

(Haraway, 1997). To maintain this truth other parts of

the body, other internal and external processes and

interactions, are excluded. Foucault (1973) argues that

there was a moment in the development of the

anatomical-clinical model of the body and disease, in

which a more complex, interconnected, organic body,

quite different to the resulting model, was glimpsed.

Glimpses of the whole body in the genocentric present

are rare, but must be sought.

What then is an alternative narrative, an alternative

spatialisation of the biological materiality of the body

and the place of the gene within this? Lippman (1992)

argues that a thorough critique of the ‘‘assumptions,

rationales and practices [is needed] to put [gene]

mapping into context with analyses that take other than

a reductionist standpoint’’ (p. 1474). Further, she

contends, ‘‘what if we gave primary importance to

relationships rather than to components, if we saw

connections, not codes?yWould current gene mapping

and sequencing activities still be a major approach to

health?’’ (Lippman, 1992). Importantly, it is from within

genetics and biology that such reimaginings of the body

are emerging (Rothman, 1995). Bickmore (1998) stresses

the importance of the spatial context of the chromosome

and the cell for gene operation and, further, the dynamic

nature of gene organisation and process. Rose (1997)

places the organism, rather than the gene, at the centre

of our experiences of development and health and

illness. He recognises the role of genes ‘‘without

subscribing to genetic determinism’’ and attempts to

reimagine the body as a three-dimensional structure that

is a ‘‘product of the constant dialectic between the

biological and the social’’ (pp. 6–7). Lewontin (2000)

echoes this, arguing that DNA’s role as ‘information

bearer’ is ‘‘subtly transmogrified into DNA as blueprint,

as master molecule’’ (p. 143) by fetishisation of the gene.

This critique is extended by Fox Keller (1994), who

argues that a gene can only function as part of biological

system and, further, that organisms have biological

mechanisms that in fact regulate gene ‘activity’. We are,

perhaps, the products of ‘‘turbulent genomes in turbu-

lent environments’’ (Dover, 2001, p. 64), ‘‘continually

constructing our own futures, albeit in circumstances

not of our own choosing’’ (Rose, 1997, p. 7). From

within the science that produces gene maps we can spot

glimpses of an organic, socially embedded body.

Gene mapping is a technical, political, and commer-

cial process that at the same moment makes the body a

genocentric space and connects that space into medical,

pharmaceutical and cultural discourses (Braun and

Castree, 1998). The reimagining of the body and health

through the gene has serious conceptual and material

consequences (Rose, 1998), as resources and technolo-

gies are injected into diagnosis and treatment of disease

and into our futures (Collins and McKusick, 2001).

Such is the dominance of these discourses in health (and

many other areas) that sites of contestation, wherever

they appear, that must be engaged with.
