Lactose Intolerance and its Link to Human Evolution

Lactose intolerance is a digestive disorder characterized by the body's inability to fully digest lactose, a sugar found in milk and dairy products. Most people on earth are lactose intolerant. However, certain populations of people aren't. They have a trait called lactase persistence which allows them to digest dairy without pain and discomfort. Evolution can help explain why we have this variation.

Glad you think so!

Informative, unbiased, and not out for attention. Well done. Though my german grandma grew up on a dairy farm, I can't drink dairy milk without horrible stomach pain. 😅 My daughter seems not to mind, though she doesn't drink straight (cows) milk anyway.

Human variation is inevitable, even within familial lineages!
