Further to Basener stands his ground at Skeptical Zone: Fisher’s Darwinian theorem is clearly false, here is Part 2: Defending the validity and significance of the new theorem “Fundamental Theorem of Natural Selection With Mutations, Part II: Our Mutation-Selection Model by Basener and Sanford:
In short, we agree with JF and ML that our paper does not show that deleterious mutations necessarily result in declining fitness. However, we have clearly falsified the converse claim, which is that genetic variance plus selection necessarily result in increasing fitness.
If Joe F and Michael L write a response, we politely request that they provide quotes from our paper that support their claims that we argue that fisher’s FTNS “is the basis for all subsequent theory in population genetics.” (Full sentence: “This is presented as correcting R.A. Fisher’s 1930 “Fundamental Theorem of Natural Selection”, which they argue is the basis for all subsequent theory in population genetics.”) We also invite them to clarify if our paper claims that “deleterious mutations are unstoppable” as seems to be implied in the title of their article, and provide quotes from the paper if they believe we support that premise.
