Question 10 Which data most strongly supports the "Out-of-Africa" hypothesis? A Fossils found in Africa are generally smaller than those found on other continents. DNA sequences from extant African hominins are more diverse than extant hominins from other continents. The synapomorphy of hominins (bipedalism) indicates that ancient humans walked out of Africa. DNA sequences from extinct hominins are more diverse than extant hominins.
