Always has been.
How? Like... literally how?
I grow kale and it looks nothing like the plant in the OP. It looks like a regular bunch of kale.
Or is this like "all 6 vegetables come from one main vegetable", kind of like how all citrus fruits comes from citron.
Just like dog breeds look very distinct, but cranked up to eleven with horrible deformities. Imagine if we continued to breed chihuahuas to have bigger heads and smaller bodies until they are 90% head. Or breed a breed of hound to be smaller with increasingly bigger ears until it's 90% ears. They would still be dogs of the same species because they can procreate together.
Artificial selection!
If you think that’s amazing - look up what bananas looked like before human cultivation. Basically any fruit or vegetable you eat is the product of centuries of humans carefully selecting what seeds to save and plant.
This is what happened
No, it's cooler than that! All these vegetables are cultivars of the same species (Brassica oleracea). Citrus trees are different species with common origins.

Its exactly like that.
