I already knew about this phylogenetic tree (although I have always heard the common ancestor be called the "wild mustard", not wild cabbage), but the article was quite interesting.
I only wish that as a PSA, they had included the reminder to people over 30 years old who hate Brussels sprouts, that the delicious ones you can eat today are not the ones they hated in their youth, and if you haven't had sprouts in years you might want to give them a second try (salted, oiled and baked, not boiled or steamed of course!)
Great point about brussel sprouts and it's truly fascinating on a number of levels. I think we're all tempted to believe the story that our palate just changes as we get older. But that's not what happened with brussel sprouts! They became cultivated differently to change their taste and so the modern ones we have are not the bitter ones we had as a kid.
I think there's a similar story for, say, canned peas which used to be nasty and made me think I didn't like peas. Granted I still don't consider myself someone who likes peas from a can, but fresh peas in a salad, or flash frozen peas in a bag that stores in the freezer, I'm open to those.
That's not to say that our tastes don't change, but brussel sprouts are kind of a fascinating mirage where it seems like the change might have been growing up into adulthood when really it was a chang in cultivation. These are just off the top of my head, but over the past couple of decades, there's been a quiet revolution in mass produced veggies on a number of levels that in each of their individual instances trace back to fascinating stories of science.
I think the sprouts trauma is the result of picking the wrong cooking method.
I was so surprised when I tried baked sprouts for the first time (use a really host cast iron skilet for even better results) that I started to believe that every vegetable can be delicious as long as you bake it!
