That’s an interesting image to be at the top of a post about the dawn of civilisation. It would be assumed that it would be more apt for a post about the end of civilisation, but no. The idea that all life on Earth came from outer space via an asteroid has recently gained credence, with scientists expressive the belief that said asteroid could have come from Mars and brought primitive life from there, and I for one find the arguments in favour highly compelling. However, I came across an article earlier today on ‘The Times’ website that suggests a meteor may also have had something to do with man’s (and woman’s) move to sedentary living and life within urban centres (I won’t call them ‘cities’, as I don’t want to get onto that debate…).
The idea is that a meteor struck in Quebec, Canada, around 12,900 years ago, and caused the onset of the colder, drier period known as the Younger Dryas. Previously, it was thought that this change in climate came about due to the rupturing of an ice dam that let a vast quantity of fresh water into the Atlantic and subsequently stopped currents carrying warm tropical waters towards Europe. Small droplets of molten rock known as spherules have been discovered in Pennsylvania and New Jersey that match chemical fingerprints of rocks in Quebec, and which suggest that they were formed under the high pressures and heat of a meteor impact in Canada. No crater has been found yet, but it suggests that the shift to agriculture as a more reliable source of food and thus eventually sedentary living that came about due to the change in climate may have been a fluke brought about by events that begun many millions of miles away from Earth. Also, this is one of the more rare occasions where two of my loves- namely archaeology and space- can come together in the same article! I am very intrigued to see whether this is definitively proved (or at least proved as much as is possible).
