02/03/2015: Stone age Britons were eating wheat 2000 years before they farmed it

Scientists have learned a lot about our distant ancestors from DNA that's thousands of years old. Like the fact that we've inherited some Neanderthal DNA, so apparently our ancestors mated with them. Now there's new research from DNA that moves on from paleo-mating to paleo-eating, The Salt reports.

About 10,000 years ago, hunter-gatherers in the Near East figured out how to grow cereal crops like wheat. The farming culture spread, and wherever it went, people traded in their spears for plows.

That's the conventional view. Apparently, it was more complicated than that.

Evidence comes from archaeologists who've been digging into Bouldnor Cliff, a submerged prehistoric site off the coast of the Isle of Wight, in the south of Great Britain. They found tools, burned nutshells and animal remains and worked wood.

"We sort of got the lunch spot of this boat-building workshop 8000 years ago," says Robin Allaby, a molecular archaeologist at the University of Warwick in England.

He says even though the locals could build boats, they were still hunter-gatherers. Agriculture didn't take off in Britain for another 2000 years.

And yet he found DNA from cultivated wheat along with the lunchtime paraphernalia. He didn't find any wheat pollen at all, so it wasn't grown there. In fact, there's never been evidence that wheat was cultivated in Britain earlier than about 6000 years ago.

Which meant the Brits must have been getting wheat from someone else, grown somewhere else.

Writing in the journal Science, Allaby says that apparently Stone Age Britons weren't isolated on their little island. It seems they were getting their wheat from Europe, where agriculture had already established itself.

"They were perfectly happy with using the products of agriculture," he says,

"But they didn't actually start farming themselves. They were interacting with the farmers some ways away, contributing to this process [of creating a Neolithic agricultural society], which is not the conventional view."

He suspects that farmers from what is now France established a regular wheat trade across the English Channel, which was narrower and shallower at the time. Which meant that the Stone Age Brits could have their cake and eat it, too.
