Given that every evolutionary outcome is about which genes survived long enough to produce viable offspring that have some of those same genes

A) at all

B) more than others

C) happened to pass on

this makes more sense, since its about sex

every other use of the same skill is happenstance

for example with C), in humans, cancer occurs mostly after sexual reproductive periods, so there is no way for that to have been weeded out of the population. Demonstrating that many non beneficial traits pass on alongside beneficial ones and its all happenstance.
