History and her-story
DNA studies reveal that throughout history, women have moved around far more than men. This is probably because they moved to their husbands' villages when they married. Scientists can work out the movements of our female ancestors by looking at stretches of our mitochondrial DNA, which is passed on only by our mothers. Similarly, they can work out the movements of our male ancestors by looking at Y-chromosome DNA, which is passed from fathers to sons.
