Did Homo sapi­ens and Ne­an­derthals in­ter­breed?

BBC Earth (Asia) - - Science -

Yes, and more than once! DNA anal­y­sis sug­gests that the ear­li­est en­counter be­tween the two species was 100,000 years ago, just as the ear­li­est wave of was mi­grat­ing out of Africa. They met Ne­an­derthals moving east­wards from Eu­rope to Asia and swapped genes. Later in­ter­breed­ing pe­ri­ods hap­pened 55,000 and 40,000 years ago, and each time we ac­quired some Ne­an­derthal genes. Un­less you are of sub-Sa­ha­ran de­scent, your genome con­tains 1-4 per cent Ne­an­derthal DNA. LV
