Guess what....wait for it........
Still fruit flies. Sorry but you probably should not have mentioned them, (the other poster above)
It would have been quite astonishing if an experiment on E. coli would have yielded fruit flies after a few years.
But joking aside, no one reasonably expects having a box of bacteria who do their thing for a few years change into something radically different such as a multicellular organism. No ecvolutionary theory suggests that a bunch of fruit flies would turn into something completely different in the course of a few years. That's a very silly straw man. Take a sizable population, divide them up and give them selection pressure and a few tens of millions of years, then we're talking.
It’s not analogous to a few years when a new generation spawns in just one week. After 40k generations of forced mutations there is no macro evolution, no new body plans,organs, novel features just mutants. Nothing like that had been observed, there are limitations to micro evolution that stops short of macro
