2.
Method of evolution according to Darwin
3.
the change in frequency of an existing gene variant in the population due to random chance
4.
a sharp reduction in the population's gene pool due to an environmental or human-caused change
5.
the reduction in genomic variability that occurs when a small group of individuals becomes separated from a larger population
6.
all of the genes in a population
7.
where the median is selected for
8.
where one extreme is selected for
9.
any movement of individuals, and/or the genetic material they carry, from one population to another
10.
where both exterems are selected for
11.
creation of a new species
12.
species cannot breed because they are in different places
13.
species cannot breed because they don't like each other
14.
species with different ancestors becoming more alike because of environment
15.
species that share a common ancestor becoming less alike because of environment
16.
same structure although the function may be different
17.
structures do the same thing, but are not the same, don't share a common ancestor
18.
structures that no longer serve a purpose
19.
remains or impressions of an organism
