The two studies also show that Africans have the most diverse DNA, and the fewest potentially harmful genetic mutations. .. One of the studies shows European-Americans have more small mutations, while the others show Native Americans, Polynesians and others who populated Australia and Oceania have more big genetic changes.&rdquo;
