Genetic Mutation……Now imagine that within a longhair Hh population a genetic mutation disabled the expression of the longhair H gene, and that mutation was reproduced over and over again within the population. The formerly longhair population would become shorthair, not because of the rearrangement of genes through sexual reproduction but because of genetic mutation. ……Another important example of microevolution through genetic mutation is when a population of insects becomes resistant to a certain pesticide, or when bacteria become resistant to antibiotics. What happens in these instances is that through mutation the insects or bacteria lose the ability to produce the enzyme which interacts with the poison. The pesticide or antibiotic therefore has no effect. But the insects or bacteria don't gain any new genetic information, they lose it. It is not therefore an example of macroevolution as it is often misinterpreted as, but microevolution. As biophysicist Dr. Lee Spetner explains, "All of the mutations that have been examined on a molecular level show that the organism has lost information and not gained it."
