Evolutionists attempt to portray insects’ growing immunity to DDT as evidence for evolution. In reality, DDT immunity develops in much the same way as bacterial immunity to antibiotics. (See Antibiotic Resistance.) There is no question of a subsequently acquired immunity to DDT, since some insects already possess it.
Following the invention of DDT, those insects that were exposed to the pesticide—and had no immunity to it—died out. However, those individuals with such immunity were initially very low in number, but survived and gradually multiplied in number. As a result, the same insect species came to consist of individuals that all possessed genetic immunity.
Naturally, as most of the population of insects came to be made up of immune individuals, DDT began to have little effect on that species. This process is popularly referred to as “insects becoming immune to DDT.”
