 Chimpanzees， they are much like us, genetically¹ and atomically, and as it turns out, cocktail² logically. Because we finally have solid evidence that chimps³ drink alcohol.Social researcher who observed while chimpanzees throw back fermented⁴ tree tap, the finding were showed up in the world society journal open science. Some biologist that the reason that we humans like adult beverages⁵ is because our primary ancestors were partial to super ripe fruits, which are hying calories and often ethyl. But there is one problem with this so called drunken monkey hypothesis, apes had not been seen dawning alcohol in the wild that is until now. The researchers were study chimps in B west Africa.In this region, people tap palm tree and allow to collect the sap fermented in small plastic containers， which they cover with leaves to prevent contamination. It turns out, for chimps who hanker hootch, the leaves are like the s banana daiquiri. The apes take the leaves, crumbles⁶ them up, dip them in the sap and then soak them dry. The drinkers were mostly male, shockingly, accounting⁷ for 34 of the 51 dozes⁸ of boozing observed. And they consume a couple leaders of the fermented bru each time they b up to the bar. I mean, tree. Whether chimps are simply taking advantage of an easily acquired calorie-rich liquid,or they especially enjoyed the sap's sweet flavor,or intoxicating⁹ effects is not known. But the questions call for another round, of research.
