World's First Farmers Genetic Identities Revealed

  • DNA Analysis shows Real Identity of Early Agricultural Man

A novel DNA analysis has shown the real identity of early agricultural man. The Eurasian farmers were the first ones to start planting crops and domesticating animals on a consistent basis.

The very first genomic sequencing of ancient human fossils from the Near East shows that they have similarities that tend to aggregate around clusters. There were several genetic forms and demographic pressures that shaped these early farmers.

The study showed that there was a trio of farming communities in the region about 10,000 years ago. Two of these groups were settled in Iran and the Levant. Another group was established in Anatolia which is modern day Turkey.

The findings were published in the journal Nature on July 25.

The study proves that agriculture became common in the region due to all the populations adopting novel technologies. These helped in the sowing of crops and the raising of livestock.

It was not because a single population replaced another extant population. The earliest examples of farming took place in the Levant region. This includes Israel, Jordan and parts of Iran. These composed two of the edges of the by-now famous Fertile Crescent.

The similarities between the farmers and the earlier hunter gatherers were also gauged by the researchers. The analysis reveals something that will go on to change the models usually subscribed to by the scientists.

In Western Eurasia, the old inhabitants descended from four major groups. These included: hunter gatherers from Western Europe, hunter gatherers from Eastern Europe and the Russian Steppes, Iranian farmers and the farming community of Levant.

This reminds us moderns of the hard fact that the present day population of Europe came from a number of heterogeneous genetic lineages of people. These were as different from one another racially as Europeans are from Asians today.

The inter-mixture of various strains and subtypes shows that the very question of race is an invalid one. So much miscegenation has occurred throughout history that hardly any stock bears any so-called purity.

DNA analysis comes to the rescue of the idea that it truly is one world with everyone carrying genetic materials in their DNA from other outgroups. Going into the genetic history of various populations gives us a whole lot of information regarding their origins and breeding patterns.

The techniques used have been honed to a razor blade and so today the results are pouring in. They may surprise many of the scientists. Farming as a practice that changed the face of the world will continue to provide us with new ideas as the cornucopia of facts is delved into by the experts.
