Evidence of Evolution

Front

How would you describe this evolution? Options: Homologous structure, Analogous structure, Structural adaption, Functional adaption

Back

Analogous structure

Front

Structures with the same parts have different functions; suggests that organisms share a common ancestry

homologous structures

Front

If an organism has a vestigial structure, that structure likely once had a function in a(n)
