Ancient DNA analysis brings into life of 11,000-year-to-year contradictions of sheep and humans to life

The sheep have been combined with human livelihood for over 11,000 years. Along with meat, their domination nurtured humans with their protein-rich milk and dressed with warm, water-resistant clothes made from their wool.

Now, an international and interdisciplinary team of researchers under the leadership of Trinity College Dublin’s geneticists and the LMU Munich and the Bavarian State Collections (SNSB) of Natural History (SNSB) have analyzed the archaeological cultural trajectors, an archaic cultural trajectory, has analyzed the archaeologically recovered 118 genomes, Which are archaeological fixing the archaeological cultural trajectory. 12 spread across the millennium and from Mongolia to Ireland.

There are conclusions Published In the journal Science,

The samples are the first to have a genome in the wide area, which seems to be ancestral for the latter population in the wide area, which seems to have a origin in the western moulon in the western part of the northern fertilizer, the samples. Let’s confirm. ,

8,000 years ago, in the early European sheep population, the team found evidence that the farmers were deliberately selecting their herds – especially for gene coding for coat color. With a similar signal in goats, it is the first evidence of human molding of biology of the second animal and shows that early flocks like today’s farmers were beautiful and unusual in their animals.

In particular, the main gene team was found near the proof of selection, known as “kit”, which is connected to the color of white coat in a range of livestock.

Furthermore, by that time, domestic sheep from Europe first separated from genomes and each other in Iran and Central Asia. However, it was not separation because people translated sheep to the west from the eastern population.

First, parallel to human cultural effects spreading from the early cities of Mesopotamia, we see sheep genome moving westwards within the fertile semi -semi -chandelier about 7,000 years ago.

Second, the emergence of the Eurasian steps and the rustic people in their west spread about 5,000 years ago, which was deeply replaced by the ancestral European human population and their culture. This process changed the make-up of the human population, for example, changed the lineage of British people to about 90%, and today introduced the Indo-European language ancestor of the tongue spoken in the continent.

From the dataset used in this study, it seems now that this mass migration was fuel by exploitation of herds and perhaps with milk and probably cheese, because it is around the same time when sheep ancestors are around the same time It was also replaced. As a result, from the bronze era, the flocks had about half a dynasty from a source in the Eurasian stapy.

Dr. Kevin Daily, Advertisement Estra Assistant Professor at UCD School of Agriculture and Food Science and an assistant assistant professor at the School of Genetics and Microbiology of Trinity is the first authors on research.

He said, “One of our most striking discoveries was a major prehistoric sheep migration from the Eurasian steps in Europe during the bronze era. What does it know about human migration during the same period, suggests that when people leave when people leave. If they went, they brought their flocks with them.

Dan Bradley, leader of Research and Professor of Population Genetics at Trinity’s School of Genetics and Microbiology, said, “This research shows how relations between humans and sheep have evolved on millennia. As an important textile resource, sheep played an important role in human cultural and economic development. “

Georis Peters, Co-relation Author, Pelionatomy’s professor, domestication research and the history of Veterinary Medicine in LMU Munich and the Director of the State Collection for Pelionatomy Munich (SNSB-SPM), said, “Formatically formal and in our study,” said, “Formatically formal and in our study Evidences of geographical origin of domestic sheep, reconciling genomic, clearly show that further transdiciplinary research is required to clarify the spread of many lands in Eurasia and Africa today.
