The Worlds First Farmers' Genetic Origins have been clarified in a study ...

In the Near East, the first agriculturalists in the Neolithic period appeared to be from genetic origins.

According to a new study published in the journalCell, the first farmers were mostly a swarm of Ice Age hunters and gatherers from the Near East and beyond, according to researchers. The researchers from the Johannes Gutenberg University Mainz and the University of Freiburg were involved in the research. The method they developed might help investigate other human evolution patterns with an unmatched resolution.

The first signs of agriculture and a sedentary lifestyle have been discovered in the Fertile Crescent, a region in the Near East, where people settled down and domesticated animals and plants about 11,000 years ago. However, this new research has revealed that agriculture and sedentism have yet to be resolved as a result of the fact that genetic analyses of prehistoric skeletons have proved that the Neolithic origins cannot be attributed to a single region. Unexpected and complex population dynamics have enacted in

The first farmers from the 14,000-year old process have rekindled.

Despite previous observations, the first Neolithic people were substantially different from other human groups from that time. Little was known about their origins, according to Nina Marchi, one of the authors of the study: "We now discover that the first farmers of Anatolia and Europe were influenced by a population admixed between hunter and hunters from Europe and the Near East." The mixing process began around 14,000 years ago, followed by a period of extreme genetic differentiation.

A new approach to model population history from prehistoric skeletons

This study was made possible by combining two methods: the production of high-quality ancient genomes from prehistoric skeletons, coupled with demographic modeling on the resulting data. According to Laurent Excoffier, the research team has used the term "demogenomic modeling" to help evaluate the differing demographic patterns in the last 30 thousand years. "We needed to accurately identify the histories of the individuals studied," said the author.

To resolve such ancient puzzles, it is critical to interdisciplinarity.

"It took over ten years to gather and analyze skeletons suitable for such a study," says the second senior author of Joachim Burger, who works with Burger at Johannes Gutenberg University. This was only possible by collaborating with numerous archaeologists and anthropologists, who helped us to spawn our theories historically." "Europe"''s first farmers have migrated from hunter-gatherer populations that ranged from the Near East to the Balkans. This was not foreseeable archaeologically.

Towards a General Model of Human Population Evolution

Genetic data from fossils (skeletons) are badly damaged and must be processed accordingly using bioinformatics, according to Daniel Wegmann of the University of Fribourg and the group leader at SIB: "With these approaches, we have not only identified the origins of the world''s first Neolithic populations, but also identified a general model of human evolution in Southwest Asia and Europe."

"Evidence of physical and temporal constraints remain, and this does not mean the end of human evolution research," says Laurent Excoffier. The team''s research plan is already established; they intend to supplement their demographic model with genomes from the earlier phases of the Neolithic and Bronze Ages to give an increasingly detailed picture of human evolution.
