PLEASE HELPPP!! I NEED THIS ASAP! WILL GIVE BRAINLIEST IF IT IS CORRECT! The diagram shows a fossil of an ancient whale skull and a skull of a present-day whale. The ancient whale is extinct and is believed to be an ancestor of the present-day whale.

(I can't insert the picture, but its an animated picture of a Pakicetus and a Gray Whale!)

What do these skulls most likely show that supports Darwin’s theory of evolution?

All populations can adapt and survive.
Only some organisms have a common ancestor.
Populations change slowly over time.
Populations rapidly become extinct.
