England. Local populations abandon cereal cultivation. The people who built Stonehenge in 3000 BC were not an agricultural society. They had been farmers before, but had abandoned cereal cultivation and returned, from around 3300 BC, to hazelnut harvesting and livestock farming as their main sources of sustenance. They consciously valued cereal cultivation and consciously decided to prefer another lifestyle. Stonehenge, moreover, indicates some kind of coordination across large areas of the British Isles, without finding evidence of specific kings or queens.
