...[cow milk] ingestion may have provided greater chances of survival during food shortages or when supplies of drinking water were contaminated.

It's interesting that cows could drink contaminated water and convert it to pure milk that humans could drink. Why didn't the cows get sick on the same contaminated water that would have sickened humans?

According to this study, the area where lactose tolerance is highest is among northwestern Europe: Ireland, Scotland, and Scandinavia.

They did get sick, they just didn't whine about how Trump doesn't wear a mask.

Another example of white privilege?

[SunkenCiv]

Another example of much greater tolerance among people of European descent.

Four stomachs to process what they ingest might have something to do with it. Plus, some bacteria affect humans but not animals and vice versa.

Your question indicates fallacious reasoning.

There are several possibilities:

1. Some of the cows undoubtedly did get sick from the contaminated water. But a caring father would nevertheless prefer giving his recently-weaned, still somewhat sickly infant child cow's milk rather than contaminated water.

2. A robust, healthy cow is more resistant to contaminated water than an aged grandfather. Etc.

My guess is that persistence lactose tolerance greatly reduced mortality in the latter stages of childhood.

A lot of animals have much stronger immunity to pathogens in water that would make humans sick. My dog can drink from streams/rivers when we go hiking and not get sick. I can’t.
