Beer Lubricated the Rise of Civilization, Study Suggests 

May beer have helped lead to the rise of civilization? It's a possibility, some archaeologists say.

Their argument is that Stone Age farmers were domesticating cereals not so much to fill their stomachs but to lighten their heads, by turning the grains into beer. That has been their take for more than 50 years, and now one archaeologist says the evidence is getting stronger.

Signs that people went to great lengths to obtain grains despite the hard work needed to make them edible, plus the knowledge that feasts were important community-building gatherings, support the idea that cereal grains were being turned into beer, said archaeologist Brian Hayden at Simon Fraser University in Canada.

"Beer is sacred stuff in most traditional societies," said Hayden, who is planning to submit research on the origins of beer to the journal Current Anthropology.

The advent of agriculture began in the Neolithic Period of the Stone Age about 11,500 years ago. Once-nomadic groups of people had settled down and were coming into contact with each other more often, spurring the establishment of more complex social customs that set the foundation of more-intricate communities.

"It's not that drinking and brewing by itself helped start cultivation, it's this context of feasts that links beer and the emergence of complex societies," Hayden said.

About 1,500 years before the modern world discovered the antibiotic tetracycline, North Africans were fermenting and consuming it, probably for most of their lives, according to a chemical analysis of the bones of people who lived along the Nile.

The ancient human remains were recovered near the Sudanese-Egyptian border, where species of tetracycline-producing bacteria inhabit the soil. This region, in Northeastern Africa, was once known as Nubia. Much of it is was flooded when the Nile River was dammed.

The practice of brewing beer was widespread in the region, including in Ancient Egypt to the north, and the researchers think the Nubians fermented Streptomyces or related species with their grain to brew a thick, sour beer spiked with tetracycline. And everyone, from about 2 years old and up, consumed it.
