What you are also ignoring and probably don't remember or know because you do not understand the theory of evolution, is that there needs to be evolutionary pressure for a species to adapt. There may have been hundreds of thousands of generations and plenty of mutations, but there has no been evolutionary pressure in your example for the fruit fly to change in any significant way so the mutations do not propagate throughout the population.
Yet the Peppered moth is an example of rapid change taking place because of a strong environmental pressure.
Another example, African elephants are being born without tusks due to poaching, researchers say
You are also deliberately ignoring the point I made before, that the fossil records show evolutionary change happening over a much longer time span. So of course persistent large scale changes have not been made in the short time span that you are referring to. The evidence in the fossil records shows though that evolution does happen over longer time scales. It is also inconsistent with your hypothesis.
Again it's a strawman argument from you because scientists aren't claiming that such large changes happen in such short time scales.

Right dipshit, let me put it another way. What evolutionary pressure is on the fruit fly populations contained in a lab to 'morph into something else'? What would it 'morph' into?
If you understood the theory of evolution (you don't) then you'd know that natural selection drives evolution. There needs to be a sustained pressure for a new evolutionary strategy to be adopted. A species won't 'morph' into a new species just out of random chance, we're talking a myriad of beneficial mutations to be provide an increase in evolutionary, which means a greater number of neutral and harmful mutations happening as well which don't propagate throughout the population.
This is why there are some species that are so well adapted to their environment that they have hardly changed in millions of years. For example:

Quote:Of all the reptiles alive today, crocodiles and alligators may be the least changed from their prehistoric forebears of the late Cretaceous period, over 65 million years ago

I am simply point int out we have studied inner species changes given hard environmental pushes under perfect evolutionary conditions to try and force an species change and at best we just make another type of 24 hour fruit fly.
Utter bollocks. The fruit fly in lab conditions are in a stable environment where they are fed and bred for experiments precisely because they are so well studied, so scientists don't want them to change.
But when scientists have ran an experiment to see how fast evolution can happen then it is entirely consistent with the theory of evolution. I am specifically thinking of the siberian foxes in Russia
https://en.wikipedia.org/wiki/Domesticated_red_fox
Quote:The Russian domesticated red fox is a domesticated form of the red fox (Vulpes vulpes). They are the result of an experiment which was designed to demonstrate the power of selective breeding to transform species, as described by Charles Darwin in On the Origin of Species.[1] The experiment was purposely designed to replicate the process that had produced dogs from wolves, by recording the changes in foxes, when in each generation only the most tame foxes were allowed to breed. In short order, the descendant foxes became tamer and more dog-like.[2][3]
The program was started in 1959 in the Soviet Union by zoologist Dmitry Belyayev[2] and it has been in continuous operation since.
And just because you are denying that you are making assumptions about the time scale it takes for evolution to happen doesn't mean to say that you're not. The fossil record shows us that evolutionary change at the type of scale you are talking about (i.e. 'morphing') happens over geological time spans.
