The above is a basic relationship between alcohol and human biology. From the biological level, people are analyzed as an animal to understand why human beings have a special addiction and dependence on alcohol and tobacco.
At the genetic level. Both humans and primates closest to humans had alcohol dehydrogenase 4(ADH4 enzyme) 6.5438+million years ago, which means that alcohol could be decomposed in our bodies 6.5438+million years ago. How did you evolve this ability? The answer is alcohol. Ripe fruit or honey contains a lot of energy and calories. After sufficient sugar is naturally fermented, alcohol with special smell is formed, which volatilizes and diffuses into the natural air.
Our ancestors used the smell of alcohol to find these fermented foods containing a lot of sugar, so for our ancestors, the smell of alcohol formed by natural fermentation meant food, and food meant survival. Therefore, some scholars believe that this love and dependence on alcohol engraved in genes cannot be simply explained by smell or taste.
In the long run, due to genetic and biological reasons, people like wine more and more, and they can't extricate themselves, so human society has a wine restriction order. But the reason why people are human beings and can build an orderly society is because people have the attributes of self-reflection and self-control. Therefore, people like to drink, but at the same time they will control getting drunk, which is also the biggest difference between us and animals.
Finally, from an unscientific point of view, drinking can cultivate people's sentiment to a certain extent, make people feel oblique wind and drizzle and lofty sentiments, get happiness, and release pressure and pain; To put it more Buddhist, after getting drunk, you can see all beings, the world and yourself.
