Penn Geneticists Identify Genes Linked to Western African Pygmies’ Small Stature

PHILADELPHIA — If Pygmies are known for one trait, it is their short stature: Pygmy men stand just 4’11” on average.  But the reason why these groups are so short and neighboring groups are not remains unclear.  Scientists have proposed various theories based on natural selection, including that Pygmies’ reduced size lowered nutritional requirements, helped them better handle hot climates, or allowed them to reach sexual maturity at an earlier age.
