Mosquitoes, Malaria, and Evolution

Because mosquitoes are showing resistance to insecticide, scientists claim evolution in action. No. This is selection, speciation, and variation, not evidence of molecules-to-man evolution.

The goo-to-you Darwinists are once again misusing the word "evolution". They claim that because humans are changing the environment of mosquitoes with insecticides, the wretched critters are evolving resistance and becoming super suckers. This is selection, speciation, and variation, not evidence of molecules-to-man evolution.

Is there new genetic information? In a way, yes, since hybridization (interbreeding) leads to adaptive introgression, where genetic information is transferred. Nothing to see here, folks, except observational science misusing that word (I don't think it means what they think it means). For that matter, it is suspected that malaria itself is a devolved relative of algae.
The war on malaria has made great strides by draping insecticide-treated netting over beds in endemic areas. Deaths worldwide have decreased by 47% since the year 2000, largely due to this innovative approach to keeping mosquito vectors away from people at risk. But a new study published in Proceedings of the National Academy of Sciences shows this seemingly innocuous measure may have triggered the development of a new “super” insecticide-resistant mosquito that will not long be deterred by the nets.

“It’s ‘super’ with respect to its ability to survive exposure to the insecticides on treated bed nets, “ explains medical entomologist Gregory Lanzaro of UC Davis. He says his team’s work “provides convincing evidence indicating that a man-made change in the environment—the introduction of insecticides—has altered the evolutionary relationship between two species, in this case a breakdown in the reproductive isolation that separates them.”
