Why do some mammals like kangaroos carry their babies in a pouch on their bellies?
Kangaroo toddlers are born early, before they have finished developing. When the baby is born, it climbs into its mother’s pouch where it stays for numerous weeks until it is sturdy adequate to pass about on its own. The baby may stay in the pouch for more than a year, mountaineering out to play more and more often. Apart from kangaroos, koalas, possum and wombats also raise their babies in a pouch. All the mammals that do this are acknowledged as marsupials.
