However, in African populations no crossbreeding had been consistently demonstrated. Now, they have identified the introgression of an extinct line of humans in the DNA of present-day African populations. "This totally unknown archaic population mixed with the ancestors of Africans and their genes have been conserved in their genome until the present," explains David Comas, full professor of Biological Anthropology at the Department of Experimental and Health Sciences (DCEXS) at UPF.<br />...<br /><a href="https://www.youtube.com/watch?v=B3YHfXPlbU0" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=B3YHfXPlbU0</a>
