An Evolutionary Whodunit: How Did Humans Develop Lactose Tolerance?

Got milk? Ancient European farmers who made cheese thousands of years ago certainly had it. But at that time, they lacked a genetic mutation that would have allowed them to digest raw milk's dominant sugar, lactose, after childhood.

It's interesting to put dairy in this perspective. TY Carrie.

I am lactose intolerant and as a lifelong guzzler of skimmed milk and lover of all dairy products, I'm glad I finally found out in my late 20's. I can chew a "lactase" tab which helps very much!

I didn't know what lactose was, but not a problem with dairy and I absolutely love, found a way to love skimmed milk (no fat). Just now finished a small bowl of cereal and going to bed. night everyone. *smiles*

Interesting article. I had often noted that Northern Europeans and descendants seemed to have less lactose intolerance than other ethnic groups.

Because early death by starvation prevents passing on genetic traits tolerating digestion of wider food sources.
If "ancient astronauts" were so advanced, why didn't they teach stupid hunans not to defecate in their drinking water?
