I’m new to Lemmy and very new to this community, but not quite so new to a whole-food plant-based diet, which I continue to find interesting as I try new plants and combinations in my cooking. So I plan to keep an eye on this community and post here things I tried and learned, and look to read about what others are doing. Here are a couple of things I’ve recently made: Tahini-cucumber-dill dressing and Desi chickpea hummus.
“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.
I like to include grain and a legume in each meal, and I’ve found one easy way to do that by making my own tempeh. I use 1.5 cups grain and 1.5 cups legume and, after measuring, cook them separately then combine and ferment with tempeh starter culture (as described in this post). My most recent batch was soybeans and 3 grains. I use the tempeh in stir-fries, stews, chilis, curries, and soups.
