A recent study of West African pygmies has revealed a little more knowledge about the somewhat unknown details of the small-statured people of Africa. It has been a mystery why the pygmy people are so much shorter(averaging 4'11") than their close relatives in the area. The research outlined in this articles reveals that the several genes that decide how tall a person is can be radically different across the world. Initially thought to be a way of adapting to the unforgiving climate and surrounding terrain, the article gives evidence to suggest it is simply the way their genes work.
