The Pygmy people are an indigenous people of central Africa. They are known for their short stature, with an average height of 150 centimeters (4 feet 11 inches) for men and 145 centimeters (4 feet 9 inches) for women.

There are a number of factors that contribute to the short stature of Pygmies. One factor is genetics. Pygmies have a higher frequency of a gene that codes for a shorter stature than other African populations. This gene is thought to have been selected for in the Pygmy population because it provides an advantage in the rainforest environment.

Another factor that contributes to the short stature of Pygmies is their diet. Pygmies typically eat a diet that is low in calories and nutrients. This diet can stunt growth and lead to a shorter stature.

Finally, the Pygmies' lifestyle also contributes to their short stature. They are nomadic people who live in small, egalitarian communities. This lifestyle does not favor the accumulation of wealth or resources, which can lead to a shorter stature.

The short stature of Pygmies is a complex trait that is influenced by a number of factors. Genetics, diet, and lifestyle all play a role in determining the average height of Pygmy people.
