Actually Brussels Sprouts, broccoli, kale, kohlrabi, bok choy, and cauliflower are all descendants of the wild mustard plant. And wild mustard is something that the Neanderthals probably ate.
(And yes I am a plant geek)
Isn’t cabbage in that wild mustard group? Not to mention cultivated mustard.
How unfortunate that the Neanderthals didn’t eat the wild mustard into extinction.
Look at all the icky veggies we moderns wouldn’t have to deal with.
