Question

The earliest mammals were very small and shrew-like. True or False

Answer 1

{I got this from online hope it helps}The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived. So yeah it’s true
