Question 5 (2 points)

When a population is challenged by changing environmental conditions:

Question 5 options:

A)

it may go extinct if the alleles necessary for success do not already exist in that population.

B)

mutations increase so that the needed allele can be found faster by natural selection.

Question 6 (5 points)

Dr. Coyne describes an experiment in which dark mice have a higher survival rate than light mice on dark soil when owls are present. We would expect that the mouse population would get darker over time. Explain this phenomenon with reference to the relevant (and violated) Hardy Weinberg assumptions.

Macroevolution:

Question 9 options:

A)

is the process by which new species originate from existing species.

unlike microevolution never involves mutations.

C)

is simply a change in the gene pool of a single species.

D)

operates on species over 3 kg only.
