An international team of researchers provided evidence that dairying arrived in Mongolia as early as 1300 BC via cultural transmission instead of population replacement or migration.


The study published on Monday in the journal Proceedings of the National Academy of Sciences revealed the origins of pastoralism in East Asian steppe Denny McLain Jersey , starting more than 2,000 years before Ghengis Khan, who founded the first Mongolian Empire in early 13th century.


The researchers led by the Max Planck Institute for the Science of Human History found that cattle, sheep and goats that were milked then were not native to the region Lance Parrish Jersey , but likely introduced by Western Steppe herders. However, ancient DNA evidence from Bronze Age Mongolians indicated minimal genetic contributions from those western herders.


The findings suggested that livestock and dairying technologies were transferred by cultural processes rather than a major population migration.


Researchers analyzed human remains from six sites in northern Mongolia associated with the Deer Stone-Khirigsuur Complex, the earliest culture associated archaeologically with pastoralism in Mongolia.


They conducted genome-wide analyses on 22 Bronze Age individuals, whose remains were radiocarbon dated to 1300 to 900 BC.


The results showed that these Bronze Age Mongolians were genetically distinct from Western steppe herders of the same time period.


The researchers also analyzed the dental calculus of nine individuals. Milk proteins were found in the calculus of seven individuals Sparky Anderson Jersey , confirming that dairy products were consumed as early as 1300 BC.


Both whey and curd proteins were recovered, and could be identified as coming from sheep, goats and cattle, according to the study.


Specifically Miguel Cabrera Jersey , they found that none of the individuals was genetically capable of digesting the milk sugar lactose.


By comparison, most Mongolians today are also not lactase-persistent, despite consuming a large proportion of their diet as dairy products.


"The 3,000-year legacy of dairy pastoralism in Mongolia poses challenging questions to grand narratives of human adaptation and natural selection Christin Stewart Jersey ," said the paper's senior author Christina Warinner from the Max Planck Institute for the Science of Human History.


"As a non-lactase persistent dairying society with a rich prehistory, Mongolia can serve as a model for understanding how other adaptations, such as cultural practices or microbiome alterations, may be involved in enabling and maintaining dairy-based cuisines around the world Nick Castellanos Jersey ," said Warinner.

The capital increase closed in March has enabled Likuid Nanotek, a manufacturer of inorganic membranes? for filtration systems, complete one of the milestones set out in its Strategic Plan 2009-2013: the unification of all areas into new facilities. The transfer will take place during the first quarter of 2011. For its part, the new production and the area of Research + Development + innovation will be operational within three to six months from that date.?


This raises a very important step for the company from Guipuzcoa (Spain) Kirk Gibson Jersey , which will be increased in this way its production capacity to develop new types of membranes and membrane bioreactor that allow new applications within the field of industrial water purification, which is specialized and has achieved be competitive thanks to the reliability, robustness and cost the life cycle of their products.
Furthermore, new developments will enable the firm to enter new markets such as food or biopharma Al Kaline Jersey , sectors that already receives inquiries and requests.




All these developments require a significant effort in R + D + i, base of the business project and to which the company operates 60% of turnover. Thus, working on interesting lines in cooperation with the CEIT, including the development of a robust filtering system and low energy membrane bioreactor wastewater treatment Alan Trammell Jersey , with an energy saving of more than 50%.
