I once read a claim that the Chinese government had funded "research" whose aim was to prove that Han Chinese are a different species to other humans. It was a physical book, not online. What might it have been? And incidentally, is the claim true?

Can fish interbreed like dogs? My SO and I have been talking about dogs lately so the mixed-breed thing has been a regular topic of conversation. Last night we were at a Thai restaurant with a large fish tank and some gigantic fish. Too big for the tank, in my opinion.

Even if they wouldn't do it on their own (mating rituals, etc.), could they do it with a scientists help?
