This amounted to a laboratory disproof which was so unambiguous that several major scientists publically repudiated Darwinism at the time, including the famous case of Richard Goldschmidt who offered up his "hopeful monster" theory as an alternative. He subsequently claimed to be being subjected by colleagues to something similar to George Orwell's ten-minute hate sessions from "1984".
That's one angle on it, there are a dozen or so others.
Similar point more forcefully argued by Michael Behe in his new Book "The Edge of Evolution."
Part of the problem people have is that "Evolution" is a term thrown around without context or definition. Even six-day creationists believe in certain kinds of evolution (and fairly rapid evolution).*
The rub comes with Darwinian Evolution, which has excluded the possibility of any "outside" mover (intelligent designer) from the outset. If you make yourself deaf, you cannot hear.
*for example, the races of man must have developed from a single pair over 6,000 years
Goldschmidt’s theory was a theory of evolution differing from previously accepted ideas. It was not at all a theory of non-evolution. That argument was settled long ago, and there is no scientific evidence that it was settled wrongly. Nothing in the research on fruit flies in any way refutes evolution (incidentally, geneticists like a certain species of fruit fly because it has only four pairs of chromosomes).
You call THAT an absolute contradictory proof?!?
You clearly do not understand the scientific method.
If evolution has been conclusively disproven, then how do you explain human remains found that are millions of years old and are different than humans in their current form?
