Edit: I meant specifically humans.
This is a very interesting thread! Thanks for asking the question, OP.
Allegedly, overbites are a result of humanity using utensils to eat.
Prominence of lactose tolerance maybe? Most animals are lactose intolerant and countries that produced a lot of dairy, the people became tolerant of it.
Do you mean a change because of agriculture, or just since Agriculture? This would mean within the past 10000 years was there any significant genetic differences. I don’t think we have a good way to know if any new Genes existed after the invention of agriculture, because we haven’t got full genomes yet from humans that long 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.
