Though this entire discussion about particular evidence on this or that matter completely misses the point I attempted to make, nevertheless here are some references which I apologize for not having provided in full initially.
It’s very easy to find any number of articles online that discuss these experiments. They are well known and documented. I’m not sure what exactly your argument is now.
Here are some articles I found that deal with the experiments. Since I haven’t read them all, I council you to read Dobzhansky’s own writing on the matter in
Heredity and the Nature of Men (1964), and
Genetics and the Origin of Species (1951). It is also described exhaustively in
Lords of the Fly by Robert Kohler. I believe Ernst Mayr also discusses the experiments in Systematics and the Origin of Species from the Viewpoint of a Zoologist, but I don’t recall, and I have grown weary with you so as to look it up again. Since I didn’t discover the experiment in online peer reviews, I will leave you to your resources to either 1) do an Internet search yourself, as articles on the experiments proliferate, or 2) stumble into a library. I am surprised, after all, that you haven’t heard of these experiments, as they are well known. Each of the works mentioned are written by very convinced and well accredited Darwinists, which I hardly mind at all. The likes of you is an entirely different story.
Here’s a link to a review of Dobzhansky’s work.

Here are a few articles I came across by dint of chance, though I haven’t read through, on these experiments from different perspectives. I reiterate, I did not learn of the experiments via online reviews, but in Dobzhansky and Kohler. You want the scoop, go to the library.

What exactly do I fail to understand about alleles? What’s so hard to understand about a fly inheriting a recessive allele from one part of each of its heterozygote parents and being bred with another fly also having a double recessive combination? Drosophila is diploid, meaning it takes two sets of alleles, represented by your high school Punnett square. How hard is that to understand? When the dominant gene is bred out by controlled breeding, and the offspring are interbred (HAVING ONLY DOUBLE RECESSIVE), the offspring will again have eyes within a few generations.

Heredity and the Nature of Men.

Possibly, though I don’t remember:
Ernst Mayr,
Systematics and the Origin of Species from the Viewpoint of a Zoologist, Harvard University Press: 1999.
You snooze at my point about the problems related with the epistemology and philosophy of science because you haven’t studied or reflected sufficiently to understand.
Here is a place to start your homework:
Hilary Putnam,
Collapse of the Fact/Value Dichotomy
Ken Wilber,
Eye to Eye
Thomas Kuhn,
The Structure of Scientific Revolutions
Even Karl Popper in
Unended Quest, perhaps the greatest philosopher of science in the last decade, admitted that Darwinism is not ideally falsifiable, though it has great explanatory power. I agree, but when its explanatory power doesn’t reach far enough, it must give space for further investigation. You do not appreciate the subtlety of my points at all.
I’m done. You haven’t listened to a word I’ve said but have been running on auto pilot stymieing everything which crosses your path. You are too immature and too unaware of the times and the literature. Further posts will not be responded to.
Take care, and perhaps in the future,
