⁨Comment⁩ on ⁨Has the time since the invention of agriculture been long enough for any evolutionary changes to occur, and if so, what are some of those changes?⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:
“Evolution” is a broad term, and human evolution definitely includes cultural evolution — the evolution of Richard Dawkins called “memes.” A meme (in that sense) is anything that is taught to others or learned from others: how to make a musical instrument from a read, how to play some particular tune, how to dance a particular dance, and so on. Obviously, there are MANY things one can learn/teach in a community, so natural selection enters the picture, with some ideas/skills becoming prevalent while others wither away. Evolution of cultural knowledge is so rapid that it can be observed: evolution in clothing style, music, language, ways of organizing, and so on.

But I think you are talking about the evolution of our physical bodies. Lactose tolerance seems to be a recent evolutionary change, still not well distributed among humans.
