Kale, cauliflower, cabbage, and Brussels sprouts are all the same species of plant.

Kale cauliflower cabbage and Brussels sprouts are all the same species of plant Vox


How is this possible? About 2500 years agoB. olearacea was solely a wild plant that grew along the coast of Britain, France, and countries in the Mediterranean. That wild form — which still exists and is known as wild mustard.

In Ancient Greece and Rome, people began growing the plant in their gardens. To maximize the amount of food they got from it, they preferentially planted seeds from plants that grew more leaves, and after many generations, this sort of artificial selection produced a leafy version of wild mustard that looked more like modern-day kale or collard greens.

Later (sometime after the year 1600), farmers selected for variants of the plant that produced enlarged leaf buds in particular. After many generations, this led to plants with huge heads of tightly rolled leaves — plants that we would call cabbage.

Elsewhere, farmers selected for enlarged flowering structures (creating broccoli and cauliflower), enlarged stems (kohlrabi), many small heads (brussels sprouts). This still goes on: in 1993, a Japanese seed company bred broccolini, a hybrid between broccoli and kai-lan, yet another form of this plant species, known as Chinese broccoli.

"Artificial Selection" = human-induced, as opposed to "Natural Selection"

We bred these plants this way.

Broccolini is only a 20 year old invention?!

So, is GMO bad or good?  Or, is some GMO bad but some good?  Do we need a way to better identify good GMO from bad GMO?  I'm trying to understand and clarify....

It's very confusing. In general GMO is not bad, but there are some bad GMO.
