Evidence for Evolution

Structures with the same parts that have different functions are called

• vestigial structures

• homologous structures

• analogous structures

• fossils

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

• close relative
• early ancestor
• unrelated organism
• embryological stage
