A genetic study of cattle has claimed that all modern domesticated bovines are descended from a single herd of wild ox, which lived 10,500 years ago.
A team of geneticists from the National Museum of Natural History in France, the University of Mainz in Germany, and UCL in the UK excavated the bones of domestic cattle on archaeological sites in Iran, and then compared those to modern cows. They looked at how differences in DNA sequences could have arisen under different population history scenarios, modelled in computer simulations.
The team found that the differences that show up between the two populations could only have arisen if a relatively small number of animals — approximately 80 — had been domesticated from a now-extinct species of wild ox, known as aurochs, which roamed across Europe and Asia. Those cattle were then bred into the 1.4 billion cattle estimated by the UN to exist in mid-2011. Read more.
Around 8,000 years ago, prehistoric hunters killed an aurochs and their grilling techniques were frozen in time.
Stone Age barbecue consumers first went for the bone marrow and then for the ribs, suggest the leftovers of an outdoor 7,700-year-old meaty feast described in the July issue of the Journal of Archaeological Science.
The remains, found in the valley of the River Tjonger, Netherlands, provide direct evidence for a prehistoric hunting, butchering, cooking and feasting event. The meal occurred more than 1,000 years before the first farmers with domestic cattle arrived in the region.
Although basic BBQ technology hasn’t changed much over the millennia, this prehistoric meal centered around the flesh of an aurochs, a wild Eurasian ox that was larger than today’s cows. It sported distinctive curved horns. Read more.
