we have killed off other homo's or evolved from other homo's, for example erectus, Homo neanderthalensis, and Homo floresiensis just to name a few. Also a species is ultimately defined as having the ability to only fornicate with orginisms of the same species.....so my question is can't there be a very old tribe of people that have only mated with each other for thousands of years and can't reproduce with other homo sapiens...making them another human species? i said this in my evolution class and everyone including the teacher mocked me
