I think Raindog has a good question. Can a student grow up to work in the hard sciences without knowing evolutionary theory?
Well. Let’s think about that. Evolutionary theory is a scientific theory, the best explanation we have at this time to explain certain facts. These facts are essentially necessary for many hard science jobs, from physics (and thus engineering) to chemistry, to astronomy, to archeology, to history to ecology to agriculture to… well, frankly, most things. It’s not just about “things change over time.” It’s about “well, this oxidizes at this rate, and this has this much residue left, so it must be that old.” Or “If light approaches at speed X, and we can determine through Y and Z that object Q is that far away… how old is object Q?” "If we introduce insecticide to this environment, how many of Y and Z will die? Will their removal from the ecosystem cause an overpopulation of V?
It is perfectly possible to go through life as a counter clerk, assembly line worker, or artist, without a working knowlege of evolutionary theory. But no one can be certain, at the point in life where a child should be educated about such things, if they will find themselves in such a position for the rest of their life.
Still, even as an assembly line worker, the education gained by learning about evolutionary theory is useful. Because it teaches you to think about things. Animals changing into other animals is a simple concept that people can understand. And if someone learns, “Okay, when the fish moved into the caves of Carlsbad, the eyes were no longer an evolutionary advantage, so they were no longer selected for, and therefore, when they no longer worked, it no longer mattered…” they have learned to think about cause and effect. This means that when someone asks them where a bottleneck exists on the line, they will be able to think, “Well, if Steve got his doors to me a bit faster, I’d have them ready to pop on the chassis.” This has led, for example, to a seperate door assembly line on the plant that makes Ford Explorers. (True example.) Or, “You know, back in the 70s, the notch on each piston that told us which way to align them was necessary. Today, thanks to precision manufacturing, we don’t need to align them manually, anymore, because they’ll only fit one way. This means that we can remove the notch, increasing the strength of the rod, decreasing the loss of energy, giving us another three horsepower at zero pollution increase.” (True example… Ford Taurus - 1986)
It’s not about evolution. It’s about knowing how to think logically and clearly about the objective world around you. Evolutionary theory is the result of some of that, and as the best possible solution to the world around us, it has to be taught in schools, or people are going to be left without significant mental tools in their toolbox.
After all, “Because it’s always been done that way.” is no way to make a better country out of America, now is it?
