I was thinking about lactose tolerance the other day and managed to scrounge up an article that I had remembered reading. This article relates the findings that lactose tolerance is something that evolved in humans rather recently.
The findings supports the idea that milk drinkers became widespread in Europe only after dairy farming had become established there—not the other way around.
This has been a contentious issue for some time now, about how/when lactose tolerance came about. The new findings support that lactose tolerance came about after dairy farming was established, and this presents a tough problem for evolution. Why would humans undertake dairy farming if they couldn’t actually eat/drink dairy products? This question alone is enough to dispel the evolutionary hypothesis. If, however, we were designed to drink milk, then it is only natural that we would search for other milk sources that we could utilize.
