1. Evidence for Evolving Species

2. * Homologous Structures – Similar body structures that connect different species to a common ancestor.

3. Similarities in Early Development – During early development all vertebrates have tails and rows of tiny slits in their throats.

4. Fossil Record – Using fossils, law of superposition, and fossil dates we can see how life has changed over time.

5. Vestigial Structures – Parts of organisms anatomy that serve no function today, but could do something in the past.
Examples:
Whale legs and pelvic bones.
Tail bones in humans
