Mothers outnumbered fathers throughout much of human history, a new DNA analysis of people around the world shows. "[Historically] more of the women were reproducing than the men," study researcher Mark Stoneking, a professor of biological anthropology at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, told Live Science in an email.
