...* selection mechanism for the struggle of existence or survival. Well, is there enough time for selection? Think lactose intolerance. That trait didn't emerge until agriculture, around 10-13k years ago, where having the lactose tolerant gene conferred a survival advantage. Roughly 98%% of Swedes but only 2%% of Thais are lactose tolerant today. And that's only a few thousand years. Think about ...

Considering that we are highly adaptable species 50 generations of kids can be enough for change. Lactose intolerance has no selective significance, unless we re-adopt pastoralism as a economic way of life. Short term molecular ...
