British scientists from Oxford University have hypothesized that man owes his origin and rise above the wild world to the ability of our distant ancestors to tolerate alcohol. We are talking about a period about 10 million years ago, when among the ancient predecessors of monkeys, there was a division into monkeys and primates proper. One of the genetic features of the latter was the ability to assimilate ethanol, which, oddly enough, became the key to the development of civilization.
The activity and survival of animals directly depends on their diet. The panda is a great example - these clumsy and downright vulnerable animals did not fall prey to evolution just because they did not compete with anyone for food. They are almost the only ones who have adapted to eating bamboo, so tough and low in calories that no one perceives it as food. But the yield of bamboo is colossal, and therefore pandas have been provided with food for millennia.
Monkeys are often omnivorous, but among fruits they prefer immature, tough and fibrous ones. In contrast, primates managed to survive by feeding on overripe and fermented, fermented fruits containing ethanol. In such food there is much more easily digestible sugar, it is much more beneficial as a source of energy, but ethanol is poison for biological organisms. Primates have adapted to tolerate regular intake of this substance calmly and transferred this skill to humans.
Light alcoholic, simple cereal beer, coarse wine and all kinds of infusions based on sugar sources, such as honey or fruit, are the basis of the diet of all ancient civilizations. Because ethanol kills germs, and light alcohol has helped solve the problem of clean water shortages for thousands of years. Plus it is a convenient source of energy - alcohol is inherently very high in calories. This was the natural state of affairs until the invention of distillation just a few centuries ago, after which alcohol became really strong and the relationship between people with it took a completely different form.
