That's simply not how genetic evolution works, though it is how
Lamarkian evolution works, which was a fairly dominant theory before
genetics as a science came to the fore.
The simple fact is that (aside from a few extreme situations) the
environment does not shape the existing genes of a living creature. If
there were a situation where passing on your genes to the next
generation depended on your ability to produce epiglottal consonants, I
could agree, but I find it quite hard to construct a plausible scenario
where that would be the case.
