yeah-----it happened
No it hasn't.
"The Russian cytologist Karpchenko (1927, 1928) crossed the radish, Raphanus sativus, with the cabbage, Brassica oleracea."5The scientist crossed a radish with a cabbage. He crossed two vegetables. This is given as an example of observed speciation of one species evolving into another species. No wonder the author disassociates himself with this "evidence."
This has nothing to do with evolution.
Crossing different types of vegetables is common and is done with fruit, dogs, beetles, worms, bacteria, and cats. Remember the Encyclopedia Britannica definition of "speciation" is "the formation of new and distinct species in the course of evolution." There is no new species when a vegetable produces a vegetable. There is no speciation. This is just another example of evolutionary smoke and mirrors to deceive the simple."
Observed Instances of Speciation
such an experiment CAN result in speciation if the NEW VEGGIE can reproduce itself---------and finds a niche-----and
GOES BALLISTIC------
Don't be silly.
