How does fossil evidence support evolution?
Fossils show connections between ancient and modern species.
Define biogeography

What is a homologous structure?
Same structure, different use
Whats is an analogous structure?
Same use, different structure
What are vestigial structures?

What is meant by convergent evolution?
Unrelated species develop similar traits
What is meant by divergent evolution?
Related species develop different traits.
What type of structure is often an example of convergent evolution?
analogous
What type of structure is often an example of divergent evolution?
homologous
How does embryology support evolution?
Similarities in embryos show shared ancestors
How does DNA sequence analysis support evolution?
Similar DNA shows close relationships between species
