We can prove you wrong quite easily, actually.
But don't let the facts get in the way of your smugness, since you seem so pleased with it.
But, wouldn't you think, since we've been playing with fruit flies for about three hundred years...
Okay, I'll bite -- exactly who do you hallucinate has been "playing with fruit flies for about three hundred years?
in Beijing, Detroit, Florence, Terra Fuego...and generations could well be in the hundreds of thousands.
Fruit flies don't have a life cycle *that* fast, m'dear... One day in the egg, seven days as a larva, six days pupating. Minimum generation time is thus about two weeks. And although people first dabbled in fruit fly experiments in the early 1900's, Drosophila didn't really take off as a test subject until after the discovery of DNA in the 1950's.
Nor was "creating a new species" the goal of these experiments, but even if it had been, that means that there have only been around 1000 fruit fly generations, total, under experimental conditions. That's a considerable amount, but hardly enough to allow the evolution of fruit flies into, say, non-flies, as you so ridiculously demand to be shown.
Do you likewise foolishly insist that geologists show you a brand new mountain range developed from flat land via plate tectonics in the past 100 years?
Wouldn't you think we'd at least get a New Fly, if the theory has anything to it at all?
Oh, you mean like this?
Hint: Ordinarily, fruit flies have only *two* wings...
It'd sure bolster your religion and its dogma--
And "it'd sure bolster" your credibility if you learned why science is not a "religion" and does not rely upon "dogma", it relies upon evidence and experimental results.
which may be why so many scientists claim to have Given Life when they clearly have not.
What *are* you babbling about here?
