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

C. Their embryos develop with similar features and stages indicates fish, turtles, and humans may share a common evolutionary ancestor.

The fact that fish, turtles, and humans share similar features and stages of embryonic development is evidence that they may have a common evolutionary ancestor. This suggests that these species share a common genetic blueprint that has been passed down from their shared ancestor. The similarities in embryonic development also support the idea that these species are related and have evolved over time through a process of common descent.
