Many are of the opinion that the platypus has been cross-bred from the duck, the otter and the beaver. Apart from the obvious, i.e. this is biologically impossible, the platypus does not exhibit the characteristics of any of these animals. Platypuses have remained virtually unchanged for as long as they have been in existence. 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. Science is of the opinion that monotremes (like the platypus) which lay eggs and marsupials and placental mammals (which have live birth) diverged from a common ancestor about a 100 million years ago.
