Why are so many people in the world unable to digest lactose?
In: Biology
We are the only animal that will drink milk from other animals willingly post maturity.
Biologically it makes no sense, Because milk is ONLY from female animal’s mammary gland, and specifically female animals that are pregnant. Its not a stable widespread food source. Pre civilization, once you wean off milk, the most common food you’ll run into is meat, fish, vegetable, and fruits, there was no point in keeping the ability to process milk.
