....To return to the four African sub-races that are members of the Black Negro race, this group contains the tallest and the shortest of all humans. The shortest are the Pygmies of the African Forests. Adult males of some tribes average about 4-3/4 feet in height. There are many biological reasons for small size; one is a poorly-understood substance called Insulin-like growth factor 1 (IGF-1). In Pygmies the genetic control of IGF-1 is different from that of other groups. Pygmies were kept as pets by some ancient Egyptian Pharaohs ? they were prized for their size and rhythmic dancing ability.
