Precis:
Studies in Africa showed that women leave their family home, while men stayed at home. The researchers found that based on found teeth. These teeth were our ancestors who lived about 2-3 million years ago. Larger teeth were men, women were less. It is not known at what women move in other regions. May be they were abducted or went there in any particular order. Men hunted in certain territories. The researchers acknowledge that the material is found in small quantities and exact analysis is impossible at this stage of discovery. Further work will be carried out.
