That do???The platypus has a tail and fur similar to a beaver, a bill and webbed feet like a duck, it produces venom like an insect, lays eggs like a chicken, but nurses its young with milk! A total hodgepodge of different species. What exactly is this strange thing called a platypus and where did it come from? Another planet, maybe? Is it a sophisticated hoax put together by practical jokers

The two extant species of Beaver (North American and Eurasian) also have different numbers of chromosomes.Tero wrote:It's the chromosomes. We do not have the same number as chimpanzees. Horses and mules do not either. Look it up in wiipedia. The offspring are nfertile due to this mismatch.
Not so sure about the Big Cats, who are still "sort" of cross-fertile in certain situations. Speciation can sometimes take a while to complee.

Apart from the problem of recombining genetic material that doesn't match, you would have the problem that the mother's immune system would be triggered by the strange fetus.
In any case, the concept of the selfish gene means that experiments like this would lead to so many failures, that the genes that enabled this kind of thing would disappear from the gene pool super-quick. Each gene "strives" to reproduce itself, to the best of it's ability, and duck-fucking crocodile genes would simply lose out to crocodile-fucking crocodile genes.
