Question

Quizplus · Accepted Answer

When group selection and individual selection are opposed, individual selection typically prevails because it acts directly on an individual's traits, while group selection acts on the group as a whole. Additionally, for group selection to be effective, groups must be small and isolated, which is often not the case in real populations. Therefore, individual selection is generally considered the primary mechanism of evolution.
