Darwinian Fairy Tales

Darwinian Fairy Tales

Textbook examples of evolution often evaporate when researchers actually study them (instead of just assuming they are true).

For example, the peacock’s tail did not evolve to please hen birds; hens don’t notice them much. The allegedly yummy Viceroy butterfly did not evolve to look like the bad-tasting Monarch (both insects taste bad). The eyespots on butterflies’ wings did not evolve to scare birds by resembling the eyes of their predators. Birds avoid brightly patterned insects, period. They don't care whether the patterns resemble eyes. Similarly, the famous “peppered moth” of textbook fame has devolved into a peppered myth, featuring book-length charges and countercharges.

And remember that row of vertebrate embryos in your textbook years ago? It was dubbed in the journal Science one of the "most famous fakes" in biology—because the embryos don’t really look very similar. And Darwin’s majestic Tree of Life? It's now a tangleweed, or maybe several of them.

We seldom see evolution happening. Michael Behe’s Edge of Evolution (2007) notes that for decades scientists have observed many thousands of generations of bacteria in the lab. And how did they evolve?

Well, they didn’t. Worse, when evolution is occasionally observed (and widely trumpeted), it often heads the wrong way. For example, bacteria evolve antibiotic resistance by junking intricate machinery, not by creating it. Cave fish lose their eyes. But we don’t need a theory for how intricate machinery gets wrecked. We need a theory for how it originates and how it develops quite suddenly. Evolution, as we understand it today, apparently isn’t that theory.

We aren’t going to improve science education by teaching Darwinian fairy tales.
