Flagellum Motor:Is this Scientific?

No AFJ, NS is certainly not directional. It seems to go toward mor complexity, but it is in fact a simple artifact. Were you to look at the distribution of complexity (measured one way or another) vs number of organisms (or even species or OTU) you would see a distribution extremely ...
