Why is a newborn kangaroo tinier than your thumb, and how does it finish growing in a pouch?
A newborn kangaroo is smaller than a jellybean: pink, blind and no bigger than the tip of your thumb. It is born so early that it looks nothing like a kangaroo yet. Then, instead of staying tucked inside its mother, it finishes growing in a pocket of skin on her belly. Why is a kangaroo born so tiny and unfinished?
