Beer lets humans settle down

Occasionally, I am taking up a topic that directed a google search to my site. Anyway, I have doubts if this is really a big scientific question as highlighted in an interview and a new book of a Munich professor. With the Neolithic Age farming was raising – and usually thought as a response to famine. Reichholf believes that humans put down roots by drinking beer. Is that a good joke right to Octoberfest this year? Cheers.
