How do analogous structures provide evidence for the theory of evolution?

• They provide evidence of common ancestry.

• They provide evidence that different species have evolved to adapt to different environmental pressures.

• They provide evidence that species evolve because they are remnants from ancestral forms.

Which of the following accurately describe vestigial structures and how they provide evidence for evolution?

• They do not have a necessary function in more recently evolved organisms, but they did in more ancestral organisms. They show change over time.

• They did not have a necessary function in more ancestral organisms, but it does in more recently evolved organisms. They show change over time.

• They have an important function in both more recently evolved and more ancestral organisms.
