If evolution had ever stumbled upon some kind of magical genetic mutation that resulted in individuals directly caring about their IGF (and improved or at least didn’t damage their general reasoning abilities and other positive traits) it would have surely reached fixation rather quickly.
CRISPR gene drives reach fixation even faster, even if they seriously harm IGF.
Indeed, when you add an intelligent designer with the ability to precisely and globally edit genes, you’ve stepped outside the design space available to natural selection, and you can end up with some pretty weird results! I think you could also use gene drives to get an IGF-boosting gene to fixation much faster than would occur naturally.
I don’t think gene drives are the kind of thing that would ever occur via iterative mutation, but you can certainly have genetic material with very high short-term IGF that eventually kills its host organism or causes extinction of its host species.
