Pesticide Resistant Insects

Let’s pretend that we started out with 1,000 cockroaches and sprayed them with an insecticide which kills 998 of them. Did the 2 survivors instantaneously evolve an immune system? Of course not! They already had the gene in their DNA gene pool which allowed them to survive the poison. The dead ones did not. They simply survived and since their offspring will likely inherit this immune gene, the new population will be immune to this particular pesticide. Whether the example is bugs becoming resistant to pesticides or rats becoming resistant to poisons, this is simply survival, not evolution. This is also proof of an Intelligent Designer. Bacteria becoming resistant to antibiotics is often used as proof for Neo-Darwinian evolution. That is beneficial mutations, aided by natural selection, taking over a gene pool. This is also pure deception. A rare mutation could cause over-production of a penicillin-destroying enzyme. While beneficial to the bacteria inside a body receiving penicillin, this is a non-beneficial mutation overall as the bacteria wastes its resources producing unneeded anti-penicillin enzymes. Thus, it is less likely to survive and is removed by natural selection.
