Play an AI-generated podcast conversation about this lesson

What is homology and how is it defined?

Homology is the property of being descended from a common ancestor. It can apply to structures, DNA sequences, or behaviors that can be traced back to a shared ancestor.

Give an example of a homologous structure in mammals.

The forelimbs of all mammals, such as bat wings, whale flippers, primate arms, and front legs of quadrupeds, are homologous.

What are some important pieces of evidence for determining if a structure is homologous?

Relative position within an organism and developmental similarities are important pieces of evidence for determining if a structure is homologous.
