In fact, the gene that allows Europeans to digest milk is different from the gene that allows certain Africans to digest milk, and evolved separately. Among other things, that's clear proof that the human species continues to evolve. Which also means that those who claim we should live on a "paleo" diet are wrong for many reasons. First off, which part of the world do they want to base their diet on? And from what specific point in the past? The same way those who claim we're better off never eating meat don't understand that we evolved as omnivores, meaning we eat more or less everything, including meat. And those who say we shouldn't cook food because our distant ancestors didn't have fire, don't get it that cooked food was what made us fully human.
So, again, you are wrong to state that no one can digest milk after the age of three or so. You can't, and you can certainly get along just fine without it. Don't go around claiming that everyone is just like you in this department.
