00:00If you asked anyone, what kind of animal is a koala, the expected answer would be a small
00:05lazy bear. Even the common English name, koala bear, reinforces this idea. But scientifically,
00:11this classification is completely wrong. Koalas belong to the marsupial family,
00:17the same family as kangaroos and wallabies, not the placental mammals that true bears belong to.
00:22The core difference. A female koala gives birth to an extremely tiny embryo,
00:27about the size of a jelly bean, which completes its full development inside a special pouch on her
00:33belly, exactly like a kangaroo. Evolutionarily speaking, the last common ancestor between
00:39koalas and bears dates back more than 160 million years.
