Small mutations form modern humans

A small genetic mutation 30,000 years ago spread rapidly in central China, and can help residents of this country resist the terrible heat and humidity.

According to a Cell report, a mutation in a gene called EDAR has retrofitted humans with additional sweat glands, a genetic modification that has proved successful and spread rapidly throughout the region.

The beneficiaries of this mutation can survive and from there, the offspring give birth to more females because of the many sweat glands that allow their bodies to easily cool in hot and humid weather.

Researchers at Harvard University (USA) said that the mutation is considered to be evolutionary success because it makes people more attractive to the opposite sex, because it allows them to grow hair / The coat is thicker or has a fuller chest, according to the Los Angeles Times.

Similar mutations in the gene that control bone density, skin color and immune system function are mostly key factors for people to adapt to different environmental conditions when Adam and Eve's children spread. radiating seed all over the globe.

Powerful computers have allowed researchers to track important genetic changes that have been linked to evolutionary changes.
