1.
a heritable trait or behavior in an organism that aids in its survival in its present environment
2.
a speciation when one species radiates out to form several other species
3.
a speciation that occurs via a geographic separation
4.
a structure that is similar because of evolution in response to similar selection pressures resulting in convergent evolution, not similar because of descent from a common ancestor
5.
the magnification of genetic drift as a result of natural events or catastrophes
6.
an evolution that results in similar forms on different species
7.
an allopatric speciation that occurs when a few members of a species move to a new geographical area
8.
an evolution that results in different forms in two species with a common ancestor
9.
a magnification of genetic drift in a small population that migrates away from a large parent population carrying with it an unrepresentative set of alleles
10.
the flow of alleles in and out of a population due to the migration of individuals or gametes
11.
all of the alleles carried by all of the individuals in the population
12.
the effect of chance on a population's gene pool
13.
a structure that is similar because of descent from a common ancestor
14.
a phrase that describes the mechanism of evolution proposed by Lamarck in which traits acquired by individuals through use or disuse could be passed on to their offspring thus leading to evolutionary change in the population
15.
a broader scale of evolutionary changes seen over paleontological time
16.
the changes in a population's genetic structure
17.
the movement of individuals of a population to a new location; in population genetics it refers to the movement of individuals and their alleles from one population to another, potentially changing allele frequencies in both the old and the new population
18.
the overarching evolutionary paradigm that took shape by the 1940s and is generally accepted today
19.
the greater relative survival and reproduction of individuals in a population that have favorable heritable traits, leading to evolutionary change
20.
the study of how selective forces change the allele frequencies in a population over time
21.
formation of a new species
22.
a speciation that occurs in the same geographic space
23.
the variety of alleles in a population
24.
a physical structure present in an organism but that has no apparent function and appears to be from a functional structure in a distant ancestor
25.
an allopatric speciation that occurs when something in the environment separates organisms of the same species into separate groups
