Molecular biologyDNA nucleotide sequenceRNA nucleotide sequenceAmino acid

2. If give the molecular sequences of several species, identify the most closely related species.

Essential Vocabulary

Species

3. Use homologous structures to explain how different organisms share a common ancestor.

Essential Vocabulary

Homologous structuresCommon ancestor

4. Explain how vestigial structures provide evidence of evolutionary history.

Essential Vocabulary

Vestigial structures

5. Explain how analogous structures arise from similar selective pressure an distantly related species.
