Genetic evidence of human invasion of the world

Data on anthropology and genes have shown that human migration from Africa took place from about 45,000 to 60,000 years ago.

When a small group of modern people migrated from the continent to continental Asia and America, their genetic diversity actually changed, according to Stanford University (USA) reports. Proceedings of the National Academy of Sciences.

However, genetic projects have yet to fully leverage the abundance of existing archaeological and anthropological data, and the university's new research is believed to provide the foundation for a deeper understanding of ancient people, as well as the genetic and medical advances.

'People are expressing very well about gene decoding, but they do not always understand the demographic history' , in order to expand the study, according to co-author Brenna Henn.

Information on anthropology can assist gene analysts to trace the genetic change over time.

For example, geneticists have identified that milk sugar resistance and gluten sensitivity began to emerge when humans expanded their population in Europe some 10,000 years ago.

Anthropology can help explain this. At that time, people went towards agriculture, including milk and wheat production, and those types of genes appeared.

This is an example of how human migration has stimulated a new form of natural selection.
