Both mammal and fish embryos contain gill slits. Similarly, whales, some snakes, and land animal embryos all exhibit hind limbs. How do the similarities in these developing organisms show relationships not evident in the fully formed anatomy?

These features show that these features were once used by the creature, but thanks to evolution the species changed. However, a part is still there, as the bone has not fully evolved out.

Explanation:

Hope this helps!

Full-grown mammals lose gill cracks and fully formed whales and snakes lose their hind limbs. They represent evidence of Common Birth and Diversity.

What do all embryos have in common?

Embryology is a branch of comparative anatomy that studies the development of vertebrates before birth or hatching.

As adults, embryos exhibit similarities that may support common ancestors.

For example, all vertebrates have cracks and tails.

Comparison of embryological development of different species also reveals similarities showing unseen relationships in fully structured anatomy.

Thus, Full-grown mammals lose gill cracks, and fully formed whales and snakes lose their hind limbs. They represent evidence of Common Birth and Diversity.
