Not really. There is an endless list of species that routinely produce perfectly viable hybrids in the wild and are still considered to be good species, starting with wolves, coyotes and jackals and working our way up to various whale species
The only standard for species classification is that there be minimal genetic interchange, and there isn’t even any staredard for what qualifies as mininal. There is certainly no reason why lynx cat hybrids couldn’t occur regularly in the wild and still leave two perfectly good species or genera.
Fylis sylvestris/lybica is found throughout Asia, Africa and in some of the more remote parts of Europe. The species overlaps considerably with the European lynx so there’s is no geographical impediment to hybridisation.
Yep. The most likley outcome of a lynx and cat encounter is that the lynx eats the cat. That’s a pretty significant behavioural impediment to crossbreeding. It would probably only be by using individuals raise dint he company of the othe species that you could hope for a peaceful encounter.
That hasn’t been the defining rule for over a hundred years, I don’t know why it still turns upo in high school textbooks. People have been aware of fertile wild hybrids at leats since Darwin’s day. A species is an approximately genetically isolated population, nothing to do with ability to hybridise.
There aren’t any rules being violated. Recent taxonomy is based on on genetic similarity, and provided two species are gentically distinct they qualify regardless of how physically close they may be or whether they cna hybridise.
The truth is nobody knows whether humans and chimps are interfertile. I’d be very suprised if we were not interfertile to some degree. The reason given for lumping humans and chimps is because of the degree of genetic similarity.
