the pendulum has swung back to my favoured theory, beer.

It seems quite obvious to me, self evident perhaps, that a man living the unburdened life of a hunter gatherer with endless grilled meats would not give that up for a loaf of bread.A research team led by Li Liu, a professor of Chinese archaeology at Stanford, has found evidence of the earliest brewmasters to date, a finding that might stir an old debate: What came first, beer or bread?
In a cave in what is now Israel, the team found beer-brewing innovations that they believe predate the early appearance of cultivated cereals in the Near East by several millennia. Their findings, published in the Journal of Archaeological Science: Reports, support a hypothesis proposed by archaeologists more than 60 years ago: Beer may have been a motivating factor for the original domestication of cereals in some areas.
