12. Fossils that show features of both ancestors (species that came before them)

1. Similarities in embryos are evidence of common ancestry.
2. descendants (species that came after them)
4. Physical characteristics, like your hair or eye color, determined by your genes (DNA).
5. Any difference between the individuals in a species or groups of organisms of any species.
7. Body parts have similar jobs but are constructed of different body structures (do not have a common ancestor)
9. Traits inherited from ancestors that no longer serve their original function
11. An ancestral group of organisms that is shared by multiple lineages.
