The DNA of some modern-day Africans show signs that our distant ancestors may have mated with an unknown, humanlike species.Courtesy of Sarah Tishkoff In a new study, scientists have found hints that some previously unknown ancestors of modern humans appear to have split off into a separate species more than a million years ago.

The new findings have appeared in a scientific journal. Visit the new Science News for Kids website and read the full story: DNA hints at ancient cousins
