well, there WERE different species of “homo”.
Note that different “species” generally don’t produce offspring that are fertile - like horses mating with donkeys to produce mules.
All “humans” today are homo sapiens - the same species. That is why a person from Ireland can mate with someone from Papua New Guinea or a person from the KhoiSan can mate with someone from the Yaroba tribe and the offspring are fertile.
we’re all the same species no matter the color of one’s skin — in fact the dark black skinned Australian aborigines are closer related to the Irish than they are to black skinned West Africans
