>>In order to make a precise change in a gene, Is that “precise” or random gas coming out of the vociferous end of your digestive tract?

Natural Selection occurs ala random mutation.

Human genetic engineering is deliberately, precisely, targeted selection.

So, your “selection is selection” assertion is FALSE.

What I take from this is that you have never studied molecular biology (the study of the function and chemical form of DNA).

Alteration of DNA occurs through many natural processes, not just random mutation. Go back and read my post #28, where I describe two of the many natural processes that change DNA. There are many more processes, but it is impossible to describe them in any detail in a forum post like this.

Natural selection does not occur at the level of DNA. Selection ("natural" and "artificial") occurs at a population level. All selection means is that the population was subjected to some force that challenged its survival, and that members of the population that were better able to survive passed more of their genes to the next generation than other members of the population. Humans have applied selective pressures to every species that we have domesticated. In the Gobi desert in distant Mongolia, I saw domestic camels compared to wild camels--and they are different. That is a result of selective pressures that humans have applied to camels. We apply selective pressures to ourselves, as well. When you decide that you want to marry a sensible conservative girl who spends little time on makeup and fashion but knows how to sew and cook and can change a tire in a pinch (but would rather ask you to change it) and you avoid the pretty, primped up liberal girl who can barely recognize a kitchen, you are exerting selective pressure on humans.

As I said, selection *is* selection, regardless of the source or type of selective pressure.

And that’s what we did with wheat. We pressured it into becoming the more efficient, modern “dward wheat” common to, well, damn near anything that’s processed. Unfortunately, this selective pressuring seems to have had unintended consequences for at least some people’s health.

Only in your ambiguous dictionary.
