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. Later, some modern humans appear to have mated with this sister species. Traces of that that sister species persist today in the DNA of some African people. The new findings have appeared in a scientific journal.
