9. Our ability to drink Alcohol and not die
For all true reasoning, humans should not be able to drink alcoholic products. Yet this is exactly what we’ve done for thousands of years. The original reasoning for this was that water was often too contaminated to drink, yet juices from fruits and whatnot were actually very good. Some of these drinks had naturally alcoholic content while others added it later. It resulted in alcoholic content being a mainstay.
Even Christian churches had services where red wine was served to represent Jesus’ blood. How were we able to survive this alcohol exposure? Simple, we adapted. One of the most interesting ways evolution is proven to humans is via the enzymes we developed known as Dehydrogenase (ADH) and Aldehyde Dehydrogenase (ALDH). They break apart alcohol, allowing it to filter out into our urine, and then we completely remove it once we use the restroom.
