A Kangaroo Is Born…Twice

The narrator laureate of the science world, David Attenborough, describes the birth of a baby grey kangaroo.
Our friends at BBC Earth describe the video:

In this video a kangaroo is born, crawls up to its mother’s pouch where a camera captures it’s development from tiny, naked, grub-like newborn into a fully grown Joey.


It’s amazing how the baby worm-like kangaroo is born automatically knowing how to get up into the mother’s pouch. Incredible.

    It’s amazing how instinct can be witnessed firsthand with something like that!

    I am teaching evolution and the taxonomy of mammals to my Honors Biology class. We just discussed how different mammals develop differently.
