The misconception is so thick in here you could cut it with a monkey.
Evolution is a fact. Evolution can be aptly defined as
the change in allele frequency over time, and that behavior is an indisputable scientific fact. Allele frequency does change with time, both in man-made and natural systems. We've sequenced the DNA or organisms (hundreds of thousands of times, by now, for some species like drosophila), and watched the allele frequencies change with time. There is no room for any debate on the issue.
