Wrong, not so much for the consideration, but in the event that you should make such a claim. For it appears that the agency has been clearly determined as "darwinian forces" and the method was mentioned as a "mathematical framework" If I read it again, I should find some more verbiage to that effect.
I just realized that you probably mean the procedure of genetic selection itself. Nothing needs to be said about that if they merely want to point out that a certain percentage (25) subject to the procedure are adaptive and functional in that they take off in "rapid evolutioin" or "accumulate in the population" (pace Nebullis) Whether that index yields the only natural fitness value we will leave ot Max Weber to sort out.
