Question

a population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. after a long period of time, the chimpanzees came back into contact but were incapable of breeding. which of the following best describes the process that occurred?

○ adaptation

○ speciation

○ convergent selection

○ stabilizing selection

Explanation:

1. Analyze "adaptation": Adaptation is about organisms adjusting to their environment, not about becoming reproductively isolated, so this is incorrect.
2. Analyze "speciation": Speciation is the process where one species splits into two or more distinct species. Here, the chimpanzee population was separated, evolved separately, and then couldn't breed (reproductive isolation), which fits speciation.
3. Analyze "convergent selection": Convergent selection is when different species evolve similar traits, not relevant here.
4. Analyze "stabilizing selection": Stabilizing selection is a type of natural selection that favors average traits, not about speciation or reproductive isolation.

Answer:

B. speciation
