It's not surprising at the level of questionability of that website.
I took the time to scroll down and found a link about the fruit fly experiments. Lo and behold I found exactly what I suspected. The site claims that the fruit fly experiments failed to produce a new species or something other then a fruit fly over millions of generations. This is a classic example of outright fraud. Fruit fly experiments are designed to track specific type of genes, or damage to specific genes as a way of understanding genetics, not as a means of producing new species. They even cite what the experiment is designed to do as its own failures!
So yes, the website is correct in that the experiments failed to produce new species, but that was never their purpose in the first place.
Don't put much weight in that website.
