Document Summary

M and n left africa 60 kya and spread out to the rest of the world around 50 kya. The source of variation in finger number can come from either genetic or environmental variation. With genetic variation they could have inherited a gene from their parents that causes a different finger number. Then with environmental variation the person could have lost a finger from hunting, an accident while using a hammer, or from frostbite for staying out in the snow too long. Culture is also a source of environmental variation and the person could have lost a finger due to some cultural activity. For example, the xhosa people in south africa would amputates a finger from a sick child because they believed it would help the child get better.
