This is Scientific American's 60-second Science. I'm Adam Hinterthuer. Got a minute?

 

A team of archeologists working in Jordan has made a discovery that represents a new chapter in the story of our ancestors' move from foraging1 to farming. The researchers unearthed2 an ancient granary. The round, mud hut dates back more than 11,000 years. A raised floor was key for keeping grain dry and out of reach of hungry rats. But what makes the find so special is that the granary was built a thousand years before people ate domesticated3 crops. The report appears in the Proceedings4 of the National Academy of Sciences.

The researchers found caches of wild barley5 and oats inside the structure. Such evidence of a dedicated6 food-storage edifice7 has never been recorded from the pre-pottery Neolithic8 age. The investigators9 say this selective cultivation10 and management of wild plants shows behaviors that led to agriculture. What’s more, the granaries were built in-between houses and buildings used for food processing, which led to the establishment of more permanent settlements. By stockpiling a food surplus, our predecessors11 produced a new societal structure and curbed12 their wandering ways. Which then led to today’s foraging for junk food in supermarket aisles13.
