Pleistocene Alcohol

November 28, 2020

Our evolutionary ancestors accidentally got drunk when they binged on fermented fruit. This still happens to modern day species of monkeys and apes dependent upon fruit for a major part of their diet. In warm tropical regions the sugar in overripe fruits naturally ferments into alcohol when airborne yeast attaches to mold growing on the fruit. Modern humans discovered the fermentation process during the Pleistocene, though evidence is scant. The oldest known evidence of humans deliberately manufacturing alcohol comes from Raqefet Cave near Haifa, Israel, and it dates to 13,000 years BP. Archaeologists actually call the site a brewery. They found traces of barley and wheat beer in stone containers. Bread is likely just a byproduct of beer-making. The euphoria from alcohol consumption is addicting and far more motivating than satisfying hunger with bread when they had plenty of fish and venison to eat and could cook grains into cereal. Archaeologists also discovered evidence of early wine-making in northern China that dates to 9,000 years ago. This wine was made with honey, rice, and grape and/or hawthorn fruit. The latter is a small apple-like fruit that grows on scrubby bushes.

Natural yeast present in the atmosphere converts sugar to alcohol and also makes bread rise.

Humans probably discovered, forgot, then rediscovered how to make alcohol dozens of times during the Pleistocene.  Humans have independently discovered the fermentation process at multiple sites around the world just in the past 6,000 years.  However, Pleistocene humans mostly used skins or wooden containers.  Evidence from such organic materials has long since decayed into dust, and the hypothesis that humans commonly manufactured alcohol for tens of thousands of years is impossible to prove.

I think alcohol is the most wonderful all-purpose medicine ever discovered by man.  For myself I prescribe alcohol to treat depression, anxiety attacks, obsessive compulsive disorder, Parkinson’s tremors, insomnia, back-ache, stomach-ache, tooth-ache, and erectile disfunction.  If I ever went to a doctor, he would prescribe 9 different drugs to treat each of these different problems.  Imagine how much that would cost.  I’d be spending half my life waiting in the pharmacy.  Oh yeah, and I also use alcohol to get high.  It’s what helps me get through the daily drudgery of my pathetic existence.
