1 Beyond the Fossil Record Evidence of EvolutionBeyond the Fossil Record
2 How Does Anatomy and Structure Show Evidence of Ancestry? Comparing the anatomy of different types of organisms often reveals basic similarities in body structures, even though their functions may be very different.
3 Common AncestorA Species from which two or more species have diverged.
10 Vestigial StructuresVestigial structures are anatomical structures of organisms in a species, which have lost much or all of their original function.Structures that are considered to be evidence for an organisms evolutionary past.
19 How are Biological Molecules a Record of Evolution? Species that share common ancestry more closely, have more amino acid sequence in common.Species that have diverged from a distant common ancestor have more differences in amino acid sequences.
