Eating Carbs


Enhanced dribble
100,000 years ago

Your saliva contains an enzyme called amylase, made by the AMY1 gene, which digests starch. Modern humans whose ancestors were farmers have more copies of AMY1 than people whose ancestors stayed as hunter-gatherers. This digestive boost may have helped start farming, settled villages and modern societies.

  1. OR, conversely, access to readily-available food without the exertion of daily hunting, and the introduction of more veggies into the diet, might have stimulated amylase production. I would say it’s a chicken/egg scenario, but fish were laying eggs eons before the first chicken ever clucked, so that conundrum has long since been laid (pun intended) to rest.
