INTRODUCTION
For thousands of years, human beings have wondered about the meaning of life.
Where do we come from? What is our purpose of life? For thousands of years, the answer is
provided by many religions, involving the idea of a Godor gods.
God made us, the story goes, and put us here for a special reason. All of these
answers regards humans as exceptional creatures. Human are not just animals. Unlike animal,
only humans have free will and conscience.
Not until modern times, and the arrival of data of a different kind, has humans able to
approach the problem of his origin from a new angle. We live in a time where reason and the
conquest of science claim to provide to all the great questions asked by the human intellect.
In 1858 July 1, Charles Darwin and Alfred Russel Wallace, has introduce to public
about a revolutionary theory concerning the origin of man, at a meeting of the Linnean
Society in London. This new theory in the perspective of science has been attracting massive
responses from the society, either inspiration or fear since then.

BIOGRAPHY OF CHARLES DARWIN
Figure 1. Charles Darwin
Early LifeNaturalist Charles Robert Darwin was born on February 12, 1809, in the tiny
merchant town of Shrewsbury, England. He was the second youngest of six children. Darwin
came from a long line of scientists. His father, Dr R.W. Darwin, was as a medical doctor, and
his grandfather, Dr Erasmus Darwin, was a renowned botanist. Darwins mother, Susanna,
died when he was only 8 years old. Darwin was a child of wealth and privilege who loved to
explore nature.
In October 1825, at age 16, Darwin enrolled at Edinburgh University along with his
brother Erasmus. Two years later, Charles Darwin became a student at Christ's College in
Cambridge. His father hoped he would follow in his footsteps and become a medical doctor,
but the sight of blood made Darwin queasy. His father suggested he study to become a parson
instead, but Darwin was far more inclined to study natural history.

Voyage on the HMS BeagleWhile Darwin was at Christ's College, botany professor John Stevens Henslow
became his mentor. After Darwin graduated Christ's College with a Bachelor of Arts degree
in 1831, Henslow recommended him for a naturalists position aboard the HMS Beagle. The
ship, commanded by Captain Robert FitzRoy, was to take a five-year survey trip around the
world. The voyage would prove the opportunity of a lifetime for the budding young
naturalist.
On December 27, 1831, the HMS Beagle launched its voyage around the world with
Darwin in tow. Over the course of the trip, Darwin collected a variety of natural specimens,
including birds, plants and fossils. Through hands-on research and experimentation, he had
the unique opportunity to closely observe principles of botany, geology and zoology. The
Pacific Islands and Galapagos Archipelago were of particular interest to Darwin, as was
South America.
Upon his return to England in 1836, Darwin began to write up his findings in the
Journal of Researches, published as part of Captain FitzRoys larger narrative and later edited
into the Zoology of the Voyage of the Beagle. The trip had a monumental effect on Darwins
view of natural history. He began to develop a revolutionary theory about the origin of living
beings that was contrary to the popular view of other naturalists at the time.

Theory of EvolutionDarwin's exposure to specimens all over the globe raised important questions. Other
naturalists believed that all species either came into being at the start of the world, or were
created over the course of natural history. In either case, the species were believed to remain
much the same throughout time. Darwin, however, noticed similarities among species all
over the globe, along with variations based on specific locations, leading him to believe that
they had gradually evolved from common ancestors. He came to believe that species survived
through a process called "natural selection," where species that successfully adapted to meet
the changing requirements of their natural habitat thrived, while those that failed to evolve
and reproduce died off.
In 1858, after years of further scientific investigation, Darwin publically introduced
his revolutionary theory of evolution in a letter read at a meeting of the Linnean Society. On
November 24, 1859, he published a detailed explanation of his theory in his best-known
work, On the Origin of Species by Means of Natural Selection.
Death and LegacyFollowing a lifetime of devout research, Charles Darwin died at his family home, Down
House, in London, on April 19, 1882, and was buried at Westminster Abbey. During the next
century, DNA studies revealed evidence of his theory of evolution, although controversy
surrounding its conflict with Creationismthe religious view that all of nature was born of
Godstill abounds today.1

THEORY BEFORE EVOLUTION
Fixity of SpeciesBefore theory of evolution is introduced to the world, humans has been in a single
group which believe that species were fixed, unchanging entities. The idea that species
are fixed and unchanging dates back to Aristotle (384-322 BC), the great Greek
philosopher and scientist.2 He based his belief on the observation of his own eyes
monkeys give birth to monkeys and humans give birth to humans.
Therefore, Aristotle concluded that one species could never give rise to another. This
is known as Theory of Types, application of Plato's Theory of Forms to biology. It states
that species reflect existence of unchanging, ideal form, the "universal" or "type", and
variation represents an imperfect manifestation of underlying type. Hence, variation was
not all that important--just "noise".3
CreationismCreationism is defined as the belief that the universe and living organisms originate
from specific acts of divine creation, as in the biblical account, rather than by natural
processes such as evolution.4 Creationist believe that God had created each species
independently at the beginning of time, and that each species then remained exactly the
same up to present. Many individuals who believe in Judeo-Christian account of creation
in the book of Genesis have banded together to form political pressure group to impose
their belief on public education.5

Before discussing more about origin of man in the context of evolution, I believe it is better
to introduce generally about the main idea behind this revolutionary theory and the
mechanism which governs the process.
EvolutionEvolution is defined as the process by which different kinds of living organism are
believed to have developed from earlier forms during the history of the earth.6 In other
word, according to theory of evolution, humans are descended from non-human
ancestors. Ultimately, every species on Earth is descended from a single common
ancestor, just as the branches of tree all spring from a single tree trunk.

Before Darwin, the theory of evolution and its mechanism has long exist in the
society of either science or theology, but it has been developed by intellectuals using
science over the period. For instances, Jean Baptiste Lamarck, a French biologist
proposed that the variations among organisms originate through a response of the
organism to the needs of the environment, and its ability to respond in a particular
direction which accounts for the adaptability of a trait.7

Darwinsmost original contribution to the theory of evolution is not the theory itself,
it was the theory of natural selection, in which explain the mechanism of how and why
evolution occurs in nature. Natural selection is a very simple idea, yet it can explain the
complex order we see around us in the biological world.
Natural selection is often explained by using the analogy of artificial selection which
is practical. In artificial selection, the breeder will choose the attributes that will
determine the survival or reproductive success of the stock being breed. In other words,
natural selection is basically artificial selection, yet with Nature - almost as a personified
agentreplacing the human breeder.8
Below shows an excerpt from Charles Darwins book The Origin of Species chapter
III as it explained the action of natural selection by beginning with struggle for
existence which we would now call ecology.
As more individuals are produced than can possibly survive, there must in
every case be a struggle for existence, either one individual with another of the same
species, or with the individuals of distinct species, or with the physical conditions of life.
It is the doctrine of Malthus applied with manifold force to the whole animal and
vegetable kingdoms.9
Next, the role of nature as a selector is emphasized by the existence of an ecological
factor that hold the size of population in check. These factor define a struggle for

existence, involving competition, predation and inimical environment.10 This will
eventually lead to differences in the ability of offspring to survive depending on the traits
they have, in which variation that cause higher survival ability in the organism will be
perpetuate to the next generation, whereas variation that cause the opposite is eliminated
as the organism is unable to survive.
The natural selection is easily illustrated by the following diagram.

Finally, after having a basic understanding of the theory of evolution and its mechanism by
natural selection, I will discuss the origin of man based on the theory of evolution.
Primate Evolutionary TreeThere are several arguments about the sequence of early ancestor of man as some
researcher argued that we are considered as the third species of chimpanzee,11while other
argued that we are considered as a new lineage of species which have been evolved from
Old World apes, which split from the rest of primates about 20 million years ago.
Evolutionary tree of primate has two main branches: prosimian and anthropoid.
Prosimians include tarsier, lorises, lemurs, and pottos. These species cannot manipulate
objects as well as other primates can, and they have relatively small brains.
While in anthropoid, there are three living branches: New World monkey, Old World
monkeys, and the hominoid (apes and humans). The split between New World and Old
World monkeys provides an example of biogeography. In the other hand, hominoid then
branched to more group of species which is represented by:Hylobates (gibbons), Pongo
(orang-utans), Gorilla (gorillas), Pan (chimpanzee)and Hominid (humans).12
The diagram below simplify the idea of the evolutionary tree of primate.

HominidPrehistoric Human
The first recognized prehistoric human remains were found in Gibraltar in 1848 and in the
Neander Valley in 1856. Initially their distinctive features were thought to be the result of
disease, but when more complete remains were found in the 1880s scientists realized that
Neanderthals were an extinct type of human being, perhaps even a different human species.
Around 1900 more Neanderthal skeletons were discovered, mainly in France, as were the
remains of another being, the Cro-Magnon -- anatomically modern -- from approximately the
same period.
Between 1891 and 1893, Eugene Dubois found a cranium and a femur in Java which he
thought belonged to a giant chimpanzee, but later decided was a human

ancestor,Pithecanthropus erectus(later calledHomo erectus). There was much resistance to
accepting Neanderthal andPithecanthropusas human ancestors. Some believed anatomically
modern man had to be older than either Neanderthal orPithecanthropus, which were
considered apelike evolutionary dead ends. Others accepted an evolutionary line going
fromPithecanthropus, via Neanderthal and Cro-Magnon, to modern man. In 1925 Raymond
Dart and his co-workers found the skull of a young child in South Africa with both human
and apelike characteristics,Australopithecus africanus. Much older than anything yet found,
it was eventually placed at the beginning of the line of human ancestors, so that the
theoretical sequence wasAustralopithecus, living a few million years ago;Pithecanthropus,
about half a million years old; Neanderthals, living between 100,000 and 30,000 years ago;
and Cro-Magnon, about 40,000 years ago.
Louis Leakey, however, believed that modern man was older than generally postulated. In
1960 he found the remains of a being with a bigger brain thanAustralopithecuswhich also
looked more human, and he called it Homo habilis. In the 1960s opinions were strongly
divided: one group was convinced Neanderthals belonged to the line of direct descent, while
another group pointed to great differences between Neanderthals and anatomically modern
humans. Some consideredAustralopithecusa real human ancestor, others thoughtHomo
habilisfit the pattern better. In time doubts were expressed about whetherHomo habiliswas
one legitimate species or several different ones. While searching for more humanlike
ancestors, Leakey discovered another species in 1959, which was later categorized as a more
robust version of theAustralopithecus-type found by Dart. In 1972 Richard Leakey and his
team at Lake Turkana discovered the almost complete skeleton of a juvenileHomo erectus-
like being about 1.5 million years old, much older than those that had been found in Asia.
This discovery madeHomo erectuscontemporaneous withAustralopithecus, which did not
fit the uniplanar picture. Paleoanthropologists proposed thatAustralopithecusrobustuswas a
8/12/2019 Creation of Mankind
15/24
pg. 15
dead-end specialization ofA. africanus, but this hypothesis began to fall apart with the
discovery of a robust type 2.5 million years old. The simple picture was beginning to blur.
Another important find was Don Johanson's discovery in Ethiopia in 1974
ofAustralopithecus afarensis, better known as Lucy, estimated to be between 3 and 4 million
years old. Mary Leakey also made discoveries of early hominids, all archaic in appearance
and between 3.6 and 3.8 million years old. Just as old are the so-called Laetoli footprints -- a
trail of human-like prints preserved in volcanic ash. More and more hominid bones have also
surfaced in Asia. Between 1985 and 1988 excavations in the Lunggupo Cave in Sechuan,
China, producedHomo erectus-like remains dated by Chinese scientists as old as 1.9 million
years, but some think they compare better withHomo habilis-like beings.
In the 1990s discoveries of new types of hominids continued to make news, such
asArdipithecus ramidusin Ethiopia, estimated to be 4.4 million years old,
andAustralopithecus anamensisin Kenya, 4.2 million years old. Additional finds of erectus-
like hominids were located in Java, Indonesia, and in Dmanisi in Russian Georgia. In 2002
Michel Brunet and his team found a complete cranium in Chad's Djurab
Desert, Sahelanthropus tchadensi, dated at nearly 7 million years old. He considers this the
earliest human forebear, but experts do not agree how these beings are actually related to
humans, and some doubt if they are related at all. Some scientists still believe in uniplanar
evolution, while others see many parallel lines. ThatHomo erectusturns out to be
contemporaneous with the laterAustralopithecusis a hard nut to crack for those who want to
have one species transform into the other.
In the twentieth century many more Neanderthal remains were also found. Those in
Western Europe have extreme brow ridges, a long head, and a heavy robust frame, while in
8/12/2019 Creation of Mankind
16/24
pg. 16
Central Europe and the Near East this form is less extreme. In Western Europe they were
contemporaneous with anatomically modern man for a short time and then seem to have
disappeared quickly, while in the Middle East Neanderthals and modern man coexisted for
about 50,000 years. Some scientists continue to believe Neanderthals evolved into modern
man; others as adamantly say modern man had evolved elsewhere and replaced Neanderthals.
In the 1990s excavations in the Sierra de Atapuerca, Spain, brought to light two different
finds: numerous remains of very early Neanderthal-like beings, dated approximately 300,000
years old; and remains of hominids dated at about 800,000 to 1 million years old, with some
Neanderthal traits but also remarkably modern. Scientists have not decided whether the latter
is a new species or a type similar to archaicHomo sapiens.
There is two theory that currently is being debated as the model for evolution of man: The
Multiregional Model and Out of Africa Model. The Multiregional Model holds that modern
man evolved out ofHomo erectusin different regions of the world more or less
simultaneously. It involves little population migration, and transitional fossils should be
found everywhere. The other theory holds that modern man evolved somewhere in Africa,
and from there spread all over the world, replacing existing archaic hominid populations.
This Out of Africa Model implies that extensive migration took place.
If the Multiregional Model is correct, early examples of modern humans should appear
simultaneously throughout the Old World, which is not yet seen in the fossil record. The Out
of Africa Model also seemed supported in the 1980s by the mitochondrial DNA research of
Allan Wilson, Rebecca Cann, and Mark Stoneking, which was used to show that all living
humans could trace part of their genetic inheritance to a single female -- a Mitochondrial Eve
-- who lived in Africa between 150,000 and 100,000 years ago. These results have been
severely criticized, however, as too ambiguous and as supposing too fast a molecular clock
rate. The researchers assumed it to be 2-4%, while others are of the opinion that 0.7% is more

accurate, which would make the ancestral Eve 800,000 years old. Critics who repeated the
tests have found other trees of descent, claiming that Asia was indicated or that there was no
support for choosing one geographic area over another.13

Paleontological evidence is the main source of information of information about life
forms that are now extinct. Fossilisation is an extremely rare, chance event; scavengers and
bacterial action normally dismember and decompose dead plant and animal structure before
they can be fossilised. 14
Fossils is often referred as an evidence of evolution as it show correlation between slight
pattern change in trait or structure and the period of time. Fossils or organisms that show the
intermediate states between an ancestral form and that of its descendants are referred to as
transitional forms.

Biochemistry and Genetics Information
The biochemical differences between living things of today are limited. This makes it
possible to measure the relatedness of different groups of organisms by the amount of the
14John Murray, Genetics and Evolution, 1999, page 60.
8/12/2019 Creation of Mankind
19/24
pg. 19
differences between specific molecules such as DNA, proteins and enzyme systems. Unlike
the information based on morphological and other phenotypic traits, the genetics information
such as DNA sequence data inform us that human are 1.2% diverged from chimps.15
One of the example of technique to measure the degree of relationship between species is
by DNA hybridisation. In DNA hybridisation biologists make a hybrid DNA molecule made
from one strand of DNA from one species joined to another DNA strand from another
species. The general rule is that the closer two species are the greater the number of hydrogen
bonds formed, so the more strongly the 2 strands are held together. If we heat single species
DNA it will need to be almost heated to boiling before enough energy is provided to break
the bonds. In hybrid DNA less energy is needed to separate the strands because there are
fewer hydrogen bonds. (Around 1 degree lower for every 1% difference in bases)16

According to the law of natural selection, such imperfections as the excessive
development of a single characteristic should not be allowed to develop and perpetuate
themselves to the extent that they harm the animal or vegetal concerned. Nevertheless, it is a
well-known fact that certain conifer plants produce chemical compounds that attract
coleoptera which then devour them. The production of these chemical compounds is
therefore responsible for the death of the plant. This process has been going on for millions of
years: natural selection does not intervene to save pine and fir trees from destruction by
insects.
Similarly, the antelope is able to escape its enemies by its extreme speed, and yet
there are species of this animal whose hooves contain glands that secrete a particular odour
which, as the antelope runs, is left on the ground. All the attacking carnivores has to do is
follow the sent in order to track down its prey. However, theory of evolution by Darwin does
not eliminate this feature to ensure survival of antelopes.17
Origin of Life

As theory of evolution state that all organisms share a common ancestor, there must be a
first living things, which come out from non-living matter accidentally in the surface of the
earth once before, without the intervention of Gods creation. Darwin speculated in a letter to
his friend Joseph Hooker that life on earth might have started in a warm little pond:
It is often said that all the conditions for the first production of a living organism are
now present, which could ever have been present.But if (& oh what a big if) we could
conceive in some warm little pond with all sorts of ammonia & phosphoric salts,light, heat,
electricity &c present, that a protein compound was chemically formed, ready to undergo still
more complex changes, at the present day such matter would be instantly devoured, or
absorbed, which would not have been the case before living creatures were formed.18
In contrast, there is a dilemma that occurs in this speculation of the formation of organic
compound from non-organic matter. In a cell, DNA can only replicate itself with the help of
some specialized proteins (enzymes). However, synthesis of these enzymes can only be
realized by the information coded in the DNA.19This condition results in the scenario being
impossible as stated by Prof Leslie Orgel:
It is extremely improbable that proteins and nucleic acids, both of which are structurally
complex, arose spontaneously in the same place at the same time. Yet it also seems
impossible to have one without the other. And so, at first glance, one might have to conclude
that life could never, in fact, have originated by chemical means.20

In conclusion, the theory of evolution by natural selection is not only at the heart of
modern biology, but is increasingly important in many other fields, from artificial intelligence
and psychology to philosophy, anthropology and even sociology. One hundred and fifty five
years after the publication of The Origin of Species (1859), the consequences of Darwins
dangerous idea are still being worked out.
Although backed with several evidence in the perspectives of science, is still not
widely accepted or understood. As we saw in this modern world, Darwins ideas of evolution
and origin of mankind are still the subject of fierce controversy. The argument between
science and religion is still not over, where various organizations and people worldwide
continue to object to the teaching of the theory of evolution in state school and universities.
In my opinion, the truth within the theory of evolution is still not strongly convincing
with more and more opposing views are gaining evidences and their own explanation of
nature to counter the evidences laid out to support the evolution. In the end, there is still no
clear line indicating whether Darwins theory either natural selection or origin of mankind is
true of false. I believe that in the future, with more research and clarity, together with enough
time, people might able to find the origin of human, to find the truth in the theory and the
beliefs in God.
