Genome maps provide the DNA sequences of chromosomes. Some scientists have compared the genome maps of a hedgehog and a sloth. What do these genome maps allow the scientists to determine?

• The color patterns of the offspring of each species

• How much the size ranges of the two species differ

• The methods of protein synthesis that each species uses

• How closely related the two species are to each other.

What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones?

• The ancestors of whales may have been land mammals

• Whales could walk if they wanted to

• Whales are preparing to evolve into land animals

• Someday whales will be able to walk and will have legs

Scientists discover that cells from two species of organisms are made up of similar proteins, suggesting a close evolutionary relationship. If the scientists do further biochemical analyses, which additional finding would support this conclusion?

• The fossils of both organisms are found relatively close to each other in the fossil record.

• The anatomical structure of both organisms is similar.

• The DNA nucleotide sequence of both organisms is similar.

• Both populations of organisms have undergone natural selection over time.
