Here we go again, this time evos want to remain willfully ignorant of the fact that functional sequence complexity and complex specified information (biology) are the same exact things. They get confused because the metrics for each are different. It's as if they think that two different phrases cannot be talking about the same thing and that because there are two slightly different metrics then they must be different things.
Dembski/ Meyer CSI (biology) is supposed to be a mathematical measure of functional information of the functional sequence complexity observed in protein family biosequences as well as their RNA and DNA antecedents
Durston et al posit their own mathematical measure of functional information, in units of Fits, of the functional sequence complexity observed in protein family biosequences has been designed and evaluated.
They are both measuring the same thing. If you have CSI (biology) it is because you have functional sequence complexity. And if you are measuring the FSC then you are measuring the CSI.
Neither Joe Felsenstein nor Patrick May can grasp that simple explanation. The stupid runs deep...
