>>11102379>Neanderthals and early humans had been different tribes of the same species.HOW CAN U BE SO WRONG BRUH
male neandertal + human woman was infertile since there are no Y neanderthal chromosomes around. Infertile offspring = not same species.
male human + female 'thal was probably at the least reduced fitness since 'thal dna in europeans and middle easterners is in inconsequential regions of the genome
same for denisovan DNA in Asians
