MORE ON THE EVOLUTION OF INSECT FLIGHT

Last Spring, I wrote a post about (among other things) how insect wings probably evolved from gills, and might have seen an intermediate use in sculling across the water's surface. This morning, there's a nice post on the same issue over at Pharyngula, that goes into far greater detail in the morphology and genetics involved, and, predictably, uses the notion to illuminate what a red herring the Creationist concept of "irreducible complexity" is.
