It’s not gaining a function; it’s magnifying one that’s already there.

Then, the terminology is wrong.

The term then should be "enhancing of function' or 'enhancing a function'.

Gain of function sounds like adding a function, and gain a function sounds like adding a function too.

If a function is already there in a species, then, it's not changing the function, but enhancing the function, sort of like my analogy of a person enhancing something that's already there, like building up your muscles or body building.

Science can be precise, but then, when the terminology is not precise, it can be confusing, especially for the layman.

BTW, I was a physics major in college, so I know exactly what science is, and science has to be precise, otherwise, it's junk science.

I think ‘gain’ is used more in the sense it is used in electronics, not in the sense of ‘acquiring.’
