All animals have ancestors.
Further information:
The platypus has only ever been a platypus. Contrary to popular opinion, it has not been an otter, a duck or a beaver. Fossils of possible platypus ancestors indicate that, if it did indeed have other ancestors, they shared the same characteristics it has today. The main difference is that earlier forms of the platypus had teeth.
Platypuses are monotremes. The exact origin of platypuses, or monotremes in general, is not well known. The platypus has only ever been a platypus. It has not been an otter, a duck or a beaver. Fossils of possible platypus ancestors indicate that, if it did indeed have other ancestors, they shared the same characteristics it has today.
Platypuses did not evolve. The platypus has always been a platypus. It is not derived from the beaver, otter, duck or any other animal. There is no actual evidence of evolution in the platypus's line. Fossils of possible platypus ancestors indicate that, if it did indeed have other ancestors, they shared the same characteristics the modern platypus has today.
Platypuses are believed to have been virtually unchanged over time. Fossils of possible platypus ancestors indicate that, if it did indeed have other ancestors, they shared the same characteristics it has today.
When a baby platypus is hatched, it does have tiny, rudimentary teeth which fall out within a few weeks. These teeth are believed to be a throwback to the platypus's ancestors, as fossilised platypus teeth have been found. Adult platypuses do not have teeth. Teeth are not necessary for platypuses, as they "chew" their food by grinding it between horny plates on their upper and lower jaws.
No. America does not have platypuses. Platypuses are endemic to eastern Australia.

No. Platypuses are endemic to eastern Australia, meaning they are not found anywhere else. No English zoos have platypuses either. As of 2013, there are no zoos outside of Australia that have platypuses.
Platypuses do not need to be in a zoo. They thrive in their native habitat, and they are not endangered. Zoos are not good places for platypuses as it is still rare for platypuses to breed in captivity.
Platypuses were not invented. They were discovered by someone.
Platypuses are found only in Australia.
