Summary: Until recently, very little was known about the genetic relationship between modern humans of the Upper Paleolithic age (the period of time between 50,000 and 10,000 years ago, also called the Late Stone age) and today's populations. But with direct DNA sequencing, researchers are discovering unexpected genetic connections between individuals on opposing sides of Eurasia. These suggest a complex history that may represent an early population structure that eventually led to Europeans and Asians.
This is a schematic of populations in Eurasia and the Americas from 45,000 to 7,500 years ago. A summary of major events in each of the time periods is on the left.
"Genetic studies of ancient individuals have become more frequent in recent years because of technology," says Fu. "As a result, we can now see the presence of multiple distinct subpopulations in Europe and in Asia, and these in turn contribute different amounts of ancestry to more recent subpopulations."
"Right now is a great time to study human evolutionary genetics because the development of sequencing technology and computing resources minimizes destruction of samples and maximizes data generation and storage," Fu says. "With large present-day genomic datasets and increased international collaboration to handle the many newly sequenced ancient datasets, there is huge potential to understand the biology of human prehistory in a way that has never been accessible before."
