- 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? 10 months 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.
