a theory

ok so my theory bout idk the future or humans but includes cockroaches
ok so im just guessing that before raid was invented flying cockroaches weren't a thing. but once raid was invented thats when people used it to kill the cockroaches. some dies and possibly some survived. and the ones that survived mutated into having wings, making them fly. thats from chemicals (bad one to be exact) so what if the polluted sky has bad chemicals and later on in the future we grow wings, like cockroaches. we clearly won't have nice fairy wings but we'll have ugly cockroach wings.
just a theory that I thought ik its stupid but just think about it
