Question

Responses

they are all mammals.
they are all mammals.

they all have similar bones in their limbs.
they all have similar bones in their limbs.

they all have hair.
they all have hair.

they all have internal skeletons.

Answer 1

The best response that provides evidence for the most recent common ancestor among humans, whales, and horses is:

they all have similar bones in their limbs.

This similarity suggests a common evolutionary origin, as homologous structures (similar bones in limb anatomy) indicate a shared ancestry among the species. While being mammals, having hair, and having internal skeletons are also true for these animals, the similarity in bone structure is a stronger indicator of a more recent common ancestor.
