Question #10
For a population to evolve through natural selection:
A.
individuals must be migrating in and out of the population.
B.
it must have a small population size.
C.
the mutation rate must be low.
D.
its members must possess inheritable variation.
E.

Question #11
Select from the choices below the statement that best describes the effect of the migration of individuals into a population.
A.
Migration of individuals into a population generally decreases the genetic variability within a population.
B.
Migration of individuals into a population generally causes no change in the genetic variability within a population because it is a case of artificial selection.
C.
Migration of individuals into a population generally causes that population to diverge to the extent that it becomes a new species.
D.
Migration of individuals into a population generally increases the genetic variability within a population.
E.
Only choices a) and c) are correct.

that are adaptive.
C.
that are acquired in an individual's lifetime.
D.
that reduce mortality.
E.
that are heritable.

The fact that fish, penguins, and dolphins all have the same basic shape is BEST explained by which of the following?
A.
Fish, penguins, and dolphins all faced the same physical constraints during their evolution and converged upon the same body plan.
B.
The similarities are probably due to random chance.
C.
The basic shapes of fish, penguins, and dolphins are vestigial structures.
D.
Divergent evolution and adaptive radiation into new niches often result in convergent evolution.
E.
Parallel evolution is common among aquatic mammals.
Question #16

subject to disruptive selection.
C.
subject to directional selection.

B.
Resistance alleles in the bacterial populations in the human body are in Hardy-Weinberg equilibrium.
C.
It takes decades or longer for organisms to evolve by natural selection.
D.
Humans have provided the selection pressure that results in more harmful strains of bacteria.
