Charles Darwin, like most 19th century scientists, believed agriculture was an accident, saying, "...a wild and unusually good variety of native plant might attract the attention of some wise old savage." Off topic, but you will note in the coming weeks that the definition of savage tends to be, not me. Maybe the best theory is that there wasn't really an agricultural revolution at all, but that agriculture came out of an evolutionary desire to eat more. Like, early hunter-gatherers knew that seeds germinate when planted, and when you find something that makes food, you want to do more of it. Unless it's this food. Then you want to do less of it. I kind of want to spit it out.
