Structures in organisms that share the same basic form due to a common ancestor.
What are vestigial structures?
Structures in organisms that have no apparent function and are residual parts from a past common ancestor.
What is the significance of convergent evolution?
It shows the convergence of form in organisms that share similar environments.
