There is another kind of variation that does not involve the genome at all, and is therefore not heritable. Yet it can produce what looks like evolution. Indeed, the results look so much like evolution that for all we know some of the best examples of evolution may be due to this nonheritable kind of variation. [It] has been observed, is well known, and is well documented.
