When comparing chick and pig embryos, the similar eyes, pharyngeal pouches, and postanal tails are evidence of
A) analogy.
B) convergent evolution.
C) common ancestry.
D) biogeography.
E) artificial selection. The presence of similar structures among embryos of various species is evidence that all species inherited such traits from a common ancestor that also possessed these traits.

The presence of similar structures among embryos of various species is evidence of common ancestry, as it suggests that these traits were inherited from a common ancestor that also possessed these traits. This is different from analogy, which refers to the presence of similar structures in different species that are not inherited from a common ancestor, but instead evolved independently through convergent evolution. Biogeography and artificial selection are not relevant to the observation of similar structures among embryos of different species.
