Cockroach evolution is being caused partially from the bait used in poisons used to control infestations:
https://www.nytimes.com/2022/05/27/s...sugar-sex.htmlBack in 1993, scientists working at North Carolina State University discovered a trait in the German cockroach, a species that inhabits every continent except Antarctica. Specifically, these new cockroaches seemed to have no affection for a form of sugar called glucose, which was strange because — as anyone who has ever battled against a cockroach infestation knows — cockroaches normally cannot get enough of the sweet stuff.
So, where did these new, health-conscious cockroaches come from?
It seems we created them by accident, after decades of trying to kill their ancestors with sweet powders and liquids laced with poison. The cockroaches that craved sweets ate the poison and died, while cockroaches less keen on glucose avoided the death traps and survived long enough to breed, thus passing that trait down to the next cockroach generation.
