b) It will promote the survival of chimpanzees with beneficial traits
c) It will increase the number of alleles for specific traits.
d) It will reduce genetic diversity.

Which of these best illustrates natural selection?

c) A community whose members work together utilizes all existing resources and migratory routes.
d) The largest organisms in a species receive the only breeding opportunities.

c) found new places on the island to live.

a) genetic drift.
b) mutation rate.
c) natural selection
d) genetic variation

A single species of squirrel evolved over time into two species, each on opposite sides of the Grand Canyon. This change was most likely due to

b) low genetic diversity in the initial population
c) the isolation of the two groups
