Quote:Given this array of human diversity in the Late Pleistocene, we might well be forgiven for thinking that Ernst Mayr's contention that "in spite of much geographical variation, never more than one species of man existed on Earth at any one time" had finally been put to bed.
Could any/all of the diverse groups interbreed?(as apparently did homo neanderthalis and homo sapiens sapiens) If so,they were the same species,if we don't know,we can't make any assertions.
