"by definition, two species could not interbreed.
Except that's not true either. Mules. Horse zebra crosses. Lion tiger crosses. All sorts of hybrids out there, and that's before you get to *insert least favourite politician/celeb*."
Get with the discussion. He said: BY DEFINITION. And that is what we are talking about in this discussion.... that old DEFINITION of species that we all learned in college biology not 14 years ago
appears to be no longer correct if we accept that Neanderthals, Denisovians and Sapiens are all different species... as was previously posited by scientists. EITHER we are not separate species OR the definition of species is incorrect.
