Interesting new theory: a comet killed off the wooly mammoth – and impelled the rise of civilization!
Experts at the University of Edinburgh analysed mysterious symbols carved onto stone pillars at Gobekli Tepe in southern Turkey, to find out if they could be linked to constellations.
The markings suggest that a swarm of comet fragments hit Earth at the exact same time that a mini-ice age struck, changing the entire course of human history.
Scientists have speculated for decades that a comet could be behind the sudden fall in temperature during a period known as the Younger Dryas. But recently the theory appeared to have been debunked by new dating of meteor craters in North America where the comet is thought to have struck.
However, when engineers studied animal carvings made on a pillar – known as the vulture stone – at Gobekli Tepe they discovered that the creatures were actually astronomical symbols which represented constellations and the comet.
Using a computer programme to show where the constellations would have appeared above Turkey thousands of years ago, they were able to pinpoint the comet strike to 10,950 BC, the exact time the Younger Dryas begins according to ice core data from Greenland.
The Younger Dryas is viewed as a crucial period for humanity, as it roughly coincides with the emergence of agriculture and the first Neolithic civilisations.
Before the strike, vast areas of wild wheat and barley had allowed nomadic hunters in the Middle East to establish permanent base camps. But the difficult climate conditions following the impact forced communities to come together and work out new ways of maintaining the crops, through watering and selective breeding. Thus farming began, allowing the rise of the first towns.

On this snow-day-that-wasn’t, a reminder from the New England Historical Society (courtesy my friend Bill Campbell), of the Great Snow of 1717 in New England:
Remembering the Great Snow of 1717 in New England
Had enough snow yet? Given the staggering Great Snow of 1717, it’s somewhat surprising that this question isn’t the official New England motto. That year, historians report that New England had probably the roughest winter it ever recorded.
So much snow fell that year, capped off by a series of storms that started in late February, that the Puritans in Boston held no church services for two successive weeks, reported Cotton Mather. The events were so unusual that he and other contemporary diarists made note of how exceptionally harsh it was throughout New Hampshire, Massachusetts and Connecticut.
Though the dates varied, the storms are most commonly cited as having occurred between February 27 and March 9, though others include storms of February 18 to the 24th as being part of the Great Snow of 1717.
Regardless of dates, for generations after it became common in New England to refer to events as having occurred either before or after the great snow. Writers including Henry David Thoreau made reference to its historical significance in their work.
Throughout the region snow totals from the back-to-back storms were recorded of four, five and six feet, with drifts as high as 25 feet. Entire houses were covered over, identifiable only by a thin curl of smoke coming out of a hole in the snow. In Hampton, N.H., search parties went out after the storms hunting for widows and elderly people at risk of freezing to death. It wasn’t uncommon for them to lose their bearings and not be able to find the houses. Sometimes they were found burning their furniture because they couldn’t get to the woodshed.
