No one argued that races were different species nor of a different genus.

race is the result of adaptation to different habitat over a long period of time coupled with some interbreeding at the margins that escaped into a habitat of it’s own. race is an evolutionary result

bert: "No one argued that races were different species nor of a different genus."

Of course, but some do argue "there's no such thing as race".
I am merely saying that human "race" is equivalent to animal "breed" and plant "variety".
They do indeed signify differences in appearance, though very little difference in terms of underlying DNA.
