text: Mutations, random changes in the genetic code, do produce “new genes” not present at creation, but the so-called “new genes” are still found at the same locus, still pair the same way in meiosis, and are still turned on and oﬀ by the same regulators, so they are really only genes of the same kind as the original, and represent only variation within kind (usually harmful variation in the case of mutations).
