Process by which two species evolve in response to changes in each other:

A change in the allele frequency of a population as a result of chance events rather than natural selection.

A change in allele frequencies as a result of the migration of a small subgroup of a population.

Movement of alleles into or out of a population due to the migration of individuals to or from the population.

Separation of species or populations so that they cannot interbreed and produce fertile offspring:

Process by which unrelated organisms independently evolve similarities when adapting to similar environments:

Describes this pattern of long, stable periods in the fossil record interrupted by brief periods of more rapid change:

Evolution from a common ancestor of many species adapted to diverse environments:

Condition in which a population's allele frequencies for a given trait do not change from generation to generation:

An inherited characteristic that increases an organism's chance of survival

By looking at the genes of some animals we can determine which living species are most closely related to each other. This also reveals which species most recently diverged from their common ancestor.

Based on the partial gene segments shown, which pair of animals are genetically most closely related and therefore most recently diverged from their common ancestor?

In the table shown, the DNA found in five primate species was compared to the DNA found in humans. The number of sequence differences was recorded. Based on the data in this table, what inference could you make about these species compared to humans?
