Template byBill Arcuri, WCSD
Said that populations have
the potential to grow exponentially
Template byBill Arcuri, WCSD
Who is Malthus?
Template byBill Arcuri, WCSD
Believed in inheritance of
acquired characteristics
Template byBill Arcuri, WCSD
Who is Lamarck?
Template byBill Arcuri, WCSD
Developed nearly identical theory of natural selection around the same time as Darwin
Template byBill Arcuri, WCSD
Who is Wallace?
Template byBill Arcuri, WCSD
Cuvier’s belief that periodic natural disasters wiped out large groups of
organisms that were replaced by organisms
from another region
Template byBill Arcuri, WCSD
What is catastrophism?
Template byBill Arcuri, WCSD
Believed that organisms were fixed and not
evolving and could be placed on a ladder of increasing complexity
Template byBill Arcuri, WCSD
Who is Aristotle?
Template byBill Arcuri, WCSD
Name of Darwin’s famous Publication
Template byBill Arcuri, WCSD
What is The Origin of Species by Means
of Natural Selection?
Template byBill Arcuri, WCSD
Islands where Darwin collected
samples
Template byBill Arcuri, WCSD
What are the Galapagos Islands?
Template byBill Arcuri, WCSD
Must already exist in a population for
natural selection to occur
Template byBill Arcuri, WCSD
What is variation?
Template byBill Arcuri, WCSD
Natural selection occurs at this level
Template byBill Arcuri, WCSD
What is the population level?
Template byBill Arcuri, WCSD
Phrase Darwin used to describe natural
selection
Template byBill Arcuri, WCSD
What is “descent with modification”?
Template byBill Arcuri, WCSD
Species concept that defines a
species based on physical
characteristics
Template byBill Arcuri, WCSD
What is morphological
species concept?
Template byBill Arcuri, WCSD
Type of speciation that occurs when a
population is geographically
separated
Template byBill Arcuri, WCSD
What is allopatric speciation?
Template byBill Arcuri, WCSD
Two species of moths have different
mating dances
Template byBill Arcuri, WCSD
What is behavioral isolation?
Template byBill Arcuri, WCSD
One species of flower blooms in the spring but another blooms in the fall
Template byBill Arcuri, WCSD
What is temporal isolation?
Template byBill Arcuri, WCSD
Hybrids between two species are
unable to mate and produce offspring
Template byBill Arcuri, WCSD
What is reduced hybrid fertility?
Template byBill Arcuri, WCSD
Happens when Hardy Weinberg
conditions are not met
Template byBill Arcuri, WCSD
What is evolution or change in
population gene frequency?
Template byBill Arcuri, WCSD
Represents the proportion of
dominant alleles in a population in the
HWE
Template byBill Arcuri, WCSD
What is “p”?
Template byBill Arcuri, WCSD
Equation for Hardy Weinberg
Equilibrium
Template byBill Arcuri, WCSD
What is p2 +2pq + q2 = 1?
Template byBill Arcuri, WCSD
Frequency of dominant allele in
the population where 16% show the recessive phenotype
Template byBill Arcuri, WCSD
What is 0.6?
q2 = 0.16q = 0.4
p + q = 1p = 1- q = 1- 0.4 = 0.6
Template byBill Arcuri, WCSD
Frequency of heterozygotes in a population where
64% show the dominant phenotype
Template byBill Arcuri, WCSD
What is 0.48 (or 48%)? p2 + 2pq + q2 = 1
p2 + 2pq = 0.64q2 = 1- 0.64 = 0.36q = 0.6, so p = .4
2pq = 2 * 0.6 * 0.4 = .48
Template byBill Arcuri, WCSD
All the genes in a population at a
given time
Template byBill Arcuri, WCSD
What is the gene pool?
Template byBill Arcuri, WCSD
Term for when a small population colonizes a new
habitat separating itself from the parent
population
Template byBill Arcuri, WCSD
What is the founder effect?
Template byBill Arcuri, WCSD
A localized group of interbreeding
individuals
Template byBill Arcuri, WCSD
What is a population?
Template byBill Arcuri, WCSD
Genetic exchange caused by migration
of organism or gametes into or out
of a population
Template byBill Arcuri, WCSD
What is gene flow?
Template byBill Arcuri, WCSD
Change in population gene pool because the population has been
nearly destroyed during an earthquake
Template byBill Arcuri, WCSD
What is the bottleneck effect?
Template byBill Arcuri, WCSD
Type of selection favoring two
extreme phenotypes
Template byBill Arcuri, WCSD
What is diversifying selection?
Template byBill Arcuri, WCSD
Type of selection favoring one
extreme of the phenotypic range
Template byBill Arcuri, WCSD
What is directional selection?
Template byBill Arcuri, WCSD
Type of selection favoring the most
common phenotype and selecting against
the extreme phenotypes
Template byBill Arcuri, WCSD
What is stabilizing selection?
Template byBill Arcuri, WCSD
Selection where two male mountain elk
fight for mating rights
Template byBill Arcuri, WCSD
What is intrasexual selection?
Template byBill Arcuri, WCSD
Female peacocks prefer males with brighter plumage
Template byBill Arcuri, WCSD
