Question

Which of the following statements provides the best scientific evidence that chimpanzees and rhesus monkeys come from a common ancestor?
A. They live in similar habitats.
B. They exhibit similar behaviors.
C. They have similar nutritional needs.
D. They have similar genetic sequences.

Answer 1

Only the last one provides an actual evidence of having a common ancestor. The rest can be  a result of living in a similar environments that  makes life easier. For example, many species live next to water, as water provides more fertile ground for plants, and they might have similar behaviors (searching for water) but they might not be closely related.

so the correct answer is D.
