Evidence of Evolution: Homologous Structures

WebJun 8, 2024 · Homologous structures indicate common ancestry with those organisms that have a functional version of the structure. Vestigial traits can still be considered adaptations because an adaptation is often defined as a trait that has been favored by natural selection. Adaptations, therefore, need not be adaptive, as long as they were at some point. WebWhich best describes how comparing homologous structures provides evidence of evolution? answer choices The genes for the body plan and forelimb layout were present in a common ancestral species vertebrates share, thus passed onto all vertebrates.
