Continental drift is a significant factor in why monotremes and most (not all) marsupials are found in Australia. This has resulted in isolation.

Why do monkeys not hibernate?

Kangaroos do not need to hibernate. There is only a very limited number of Australian marsupials which hibernate, and they are only animals which live in alpine regions. Kangaroos are found all over Australia except for the Australian Alps. Everywhere else, the climate is temperate enough for kangaroos to survive and find food without any need for hibernation.


Does the Cheyenne mountain zoo in Colorado have platypuses?

No. In 2013, there are no platypuses in zoos anywhere outside of Australia. Platypuses are native Australian animals, and therefore protected by law. Only a limited number of facilities in Australia keep them for either display or research purposes, and there are very strict government controls on the housing and keeping of these monotremes.

Why are there so many species of marsupial mammals in Australia?

The main theory for this seems to be that, when the continents shifted and separated thousands of years ago, the Australian continent was left without any large predators. Unlike other continents, which most likely had marsupials and monotremes as well, the Australian continent provided a safe haven for the many unique species to grow and proliferate without being wiped out by larger species.

What three characteristics make mammals different from any other animal?

There are several characteristics that are indicative of mammals, but only two are definitive. It is easier to understand things if you know that there are three types of mammal. Almost all mammals are eutherian, or true mammals. A much smaller group are the marsupials; all but one species of these is found only in Australia and its islands. The remaining group, the monotremes, is limited to that same area.The relevant characteristics are : -Three tiny bones in the ear are absolutely definitive; all mammals have them and no other animals do. The bones are hammer, anvil and stirrup.Mammals feed their neonates by milk supplied through the female's skin; this also is definitive. Eutheria have nipples on which the newborns suck. Marsupials and monotremes have a skin patch which the young lick.Mammals are hairy. All mammals have hair, although some have only traces. Hair is not definitive - many insects have it. (Look at a honey-bee through a magnifying glass!)Almost all mammals give birth to live young, but the three species of monotremes lay eggs. When the egg hatches it is still fed on mother's milk.
