There are several groups of pygmies that can be found in Central Africa, South-East Asia and Australia. There are several theories of where these people originated from including that they were the first to migrate out of Africa, but the genetic evidence does not support the theory. Another theory suggests that pygmies are the result of human adaptation to living in the rainforest with minimal sunlight, low calcium levels and reduced levels of growth hormone and growth hormone receptor.
