RE:"Were the three homos like three different bears.....grizzlies, polar and black bears or was their relationship more distant?"

Similar but perhaps more closely related. One definition of a species is the ability to breed and create viable-reproductable offspring. If Neandertal genes exist today it would suggest at least Cro-Magnon and Neandertal were close enough to be capable of that.


What would happen if a grizzly cross bred with a polar bear? Is that not possible? I guess now. That would create the equivalent of a mutt. Never realized how distinct some species are. I suppose Orcas can't mate with other types of whales. Its interesting how dogs can cross breed so easily.
