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:

• Adaptation: Refers to a trait that helps an organism survive in its environment. The key here is the inability to breed, not just adaptation to an environment.
• Speciation: Occurs when a population splits into two or more reproductively isolated groups. In this case, the chimpanzee population was separated (geographic isolation), and over time, they became unable to breed (reproductive isolation), which is a hallmark of speciation.
• Convergent selection (convergent evolution): Is when different species evolve similar traits. This is not relevant as we are talking about a single population that split.
• Stabilizing selection: A type of natural selection that favors average traits. It does not explain the reproductive isolation seen here.

Answer:

speciation
