   This in turn may reinforce the idea that the successful spread of modern humans from Africa after about 60,000 years ago played at least a role, if not the most significant role, in the physical extinction of other forms of humans outside of Africa, however, at least some of those other forms of human did not go completely extinct, since their DNA lives on in us today through ancient interbreeding between the archaic and early modern populations. This leaves open the fascinating possibility that even floresiensis might have contributed some of its DNA to living groups in the region, if there was at least a short overlap between floresiensis and sapiens about 50,000 years ago.
