I learned this from my brother when I was harvesting Job's Tears in the garden. A bunch of foxtail seeds kept landing in the bowl, and looked just about big enough to be a grain - I commented that it seemed likely that some of our grains must have evolved that way, getting selected because they got harder to distinguish from the main plant. He was like "yeah... that's basically the story of Rye" lol. It was something I'd never thought about, but actually trying to harvest a grain made it really clear.
