... a common mistake believed by biologists who disregard the possibility of associative and selective mating. This has not disregarded at all. But it is irrelevant, and it can be shown to be irrelevant both experimentally and mathematically. There's been decades of work on imprinting and other selective mating mechanisms (including temporally dispersed hatching among others). It really doesn't matter. The examples you cited are all of the type referred to as artificial selection (as opposed to natural selection). This places a huge coefficient of selection on certain phenotypes in the population. The thrust of the work is that under conditions of natural selection gene therapy will have no affect on the course of human evolution. Look at it this way: Assume that the mutation rate for any given gene is roughly .00001. Now assume that there are around 200 million live births per year. On that basis alone we would expect 2,000 such mutations to spontaneously occur each year. Whether those mutations increase in frequency depend on the size of the population and the coefficients of selection. If the adaptive value of those mutations is not significantly different than the allotype that gave rise to them you will see drift factors become paramount, and here the smaller the population the more important drift becomes.
