The research adds to a growing body of evidence suggesting that sexual rendezvous between different archaic human species may not have been unusual. Source 7p.
This is not a surprise to me. I figured as we became closer and closer to our current species that other human species would still interbreed to help the strongest traits be carried on. I can see this happening in the future too as we continue to evolve and shape who we will be in the future as we continue to interbreed together.
