Archaeologists have discovered a 4,500 year old settlement, on the Ausable River, near the shore of Lake Huron in Canada. The find rewrites the history of the Canadian province of Ontario, proving that people were living a sedentary lifestyle at that time, even though they lacked agriculture and pottery. Among the discoveries is a 4,500 year old house – the oldest ever found in the province. “It’s semi-subterranean – it’s dug partially down into the ground,” said Professor Chris Ellis of the University of Western Ontario. He led the team that made the find. “It’s as old as the pyramids really.” The team released a picture of the house, which can be seen at the top of this article. After the house was abandoned it was hit by flood waters. Garbage was piled on top of it – something that helped the archaeologists reconstruct what the structure looked like. “Because we have the garbage lining the bottom of it we get an idea of the shape of it,” said Professor Ellis. “Also we have the stains left by the posts (that) supported the roof.” Those posts “are fairly large – you’ve got 18-20 centimetre across logs being used to do this.” [...]
