species mated with our own species tens of thousands of years ago in Africa.</span> <span data-start-time='12979' data-end-time='29750'>Researchers say the study provides evidence that present-day West Africans can link about 2 to 19 percent of their genetic ancestry to an extinct human species.</span> <span data-start-time='29750' data-end-time='36188'>The study describes the species as a &ldquo;ghost population.&rdquo;</span> <span data-start-time='36188' data-end-time='48667'>Scientists involved in the research estimated that mating between the two species happened about 43,000 years ago.</span> <span data-start-time='48667' data-end-time='60708'>Homo sapiens, the species of human that exists today, first appeared more than 300,000 years ago in Africa.</span> <span

with two early human species, the Neanderthals and the Denisovans.</span> <span data-start-time='77229' data-end-time='89063'>The species have been extinct for thousands of years, but modern human populations outside Africa still carry DNA from both.</span> </p></div><div class='control-buttons-sticky' style='display:none;'><div class='control-buttons'><button title='Back' class='back'
