That's because other people are thinking about it so you don't have to. I drive a car every day, but the last thing on my mind is how they refine gasoline from crude oil. Doesn't mean somebody's not worrying about it somewhere along the line.
LOL...only your trouble is the other people thinking about it are coming to these conclusions:
Quote of the day:
The essence of the theory of evolution is the hypothesis that historical diversity is the consequence of natural selection acting on variations. Regardless of the verity it holds for explaining biohistory, it offers no help to the experimenterwho is concerned, for example, with the goal of finding or synthesizing a new antibiotic, or how it can disable a disease-producing organism, what dosages are required and which individuals will not tolerate it. Studying biohistory is, at best, an entertaining distraction from the goals of a working biologist.
