79. Natural selection acts on the diversity in and among species by
a. Ensuring that only organisms that are fittest and best adapted to their environment survive and
reproduce.
b. Ensuring that only organisms that show no variation from other members of their population
survive and reproduce.

80. A paleontologist is comparing the fossilized remains of 2 primates. Both animals had a prehensile tail
(a tail that can grip like a hand). What can be concluded from this evidence?
a. They are not related.
b. They lived on the ground.
c. They evolved from a common ancestor.
d. They had bipedal locomotion.
81. Which could be considered biomolecular evidence of an evolutionary relationship?

b. presence of embryonic gill slits
c. similar anatomical structures
d. presence of identical proteins
82. A particular allele in mice is lethal in homozygotes. Heterozygotes, however, develop normally. Why does
this allele remain in the population?
a. Homozygous mice pass the allele to their offspring.
b. The recessive allele is masked in heterozygotes.
c. Natural selection selects for the homozygous individual for normal alleles.
d. Natural selection selects against the heterozygous individual.
