In reply to a few posts , I believe the species were created seperately but may have looked and been geneticaly different.
Maybe if I used the hypothetical situation of the Australian aborigne continuing to be isolated for many years rather than mixing with the general population of the planet and maybe eventually becoming unable to bare children with someone from the outside world...now lets say for argument that the nummber of aborigines was equal to the population of the other land masses, who would be the "new" /or "sub-species" and who would keep the sapien label, how would it be decided? or would we develope two new labels? , personaly if this happened in reality I do not think we would classify each other as something else, therefore our way of classifying earlier humans would change wouldnt it? Due to the judging by genetic differences or and non breeding between the populations, the yardstick of the hypothetical present day would be the genetic difference between Aborigine and non-aborigine
