Question

Which piece of evidence indicates fish, turtles, and humans may share a common evolutionary ancestor?

A. Their mature forms are all completely different.
B. Their genes are all activated in the same patterns.
C. Their embryos develop with similar features and stages.
D. They all have the same genetic information.

Answer 1

Answer: Their embryos develop with similar features and stages.

Explanation: Took the quiz and it was right. :)

Answer 2

C. Their embryos develop with similar features and stages.

This concept is known as embryological homology, which refers to the similarities in the early stages of development of different species. During embryonic development, many organisms share common features, such as the presence of a tail, pharyngeal pouches, and limb buds, which suggest a common ancestry.
