NerfHerder, I bet you’re going to find this topic really interesting as you get into it.
Related to the starvation issue, there was an author interviewed on NPR about a week ago, talking about the long relationship between humans and dogs, how we domesticated wolves, etc. Discussing some particular point, the interviewer (one of the well known NPR voices) made a comment to the effect, “I’m picturing our ancestors, living as hunter-gatherers, and I imagine them always living on the edge of subsistence and starvation.”
To his credit, the author corrected him and explained that from what we know such people actually had a fairly steady food supply most of the time.
But what struck me was the reminder that the interviewer’s assumption is really the standard line most people today seem to have grown up with. Is it still in middle school history books or something? I know I kind of half assumed the same thing until, at some point, I thought to myself, “So pre-agricultural humans were living just as other species within ecosystems. They were basically omnivores, eating what was available, much like, say, bears or racoons. So if bears and racoons aren’t routinely struggling with starvation, why would humans have been?”
Call me easy to please, but for me that was quite a little insight! ;D
On the origins of agriculture, there are quite a few theories. Here’s one list:

I don’t find any of those theories fully convincing, and some seem clearly wrong. But it’s fascinating to think about.
