... why should we think that the Haldane Limit poses any kind of problem for human-chimp ancestry? In order for there to be a problem, .... we would need to know that humans and/or chimps have more than 1,667 beneficial substitutions than their common ancestor had. Although we know the nucleotide similarity between chimpanzees and humans, we don't know how many of those nucleotides represent mutations which are beneficial/neutral/deleterious (especially since a single mutation can alter many nucleotides at once). We haven't done an exhaustive investigation of the function of all our alleles yet.
Walter ReMine approaches the problem this way: Start with the things evolutionists claim. They claim that since the time humans diverged from chimps, the following novel adaptations originated or greatly improved: upright posture, hand dexterity, voice box, speech, language, the distribution of hair, the tripling of brain size, and appreciation of music, to name a few. Again, start with the things evolutionists claim. Those things would have to be explained within the Haldane Limit (~1,667 beneficial substitutions, plus some number of neutral substitutions which do nothing to help adaptation).
So what can a beneficial substitution do? Again, ReMine says, start with the things evolutionists claim. Look especially for their experimental demonstrations of what beneficial substitutions can do. Well, the classic example of natural selection in action (given abundantly in evolutionary textbooks) is sickle-cell anemia. Perhaps a better example is the Galapagos finches, which evolutionists claim evolved different beak sizes depending on the available food sources. So how many beneficial substitutions were required to achieve the improved beak size? A hundred? Ten? We can err to the favor of evolutionists by assuming the smallest possible number: One. It takes at least one beneficial substitution to improve the beak size. That's the kind of power in one beneficial substitution.
Can all the novel human adaptations be explained within the Haldane Limit (~1,667 beneficial substitutions)? Evolutionary geneticists have scarcely begun to discuss this problem, must less solve it. There is virtually nothing on this issue published in the evolutionary genetics literature.
Haldane's Dilemma was never solved. It is a scandal.

Kryptid again posted a reference to a non-peer-reviewed internet web-page by an author who is not an evolutionary geneticist. It's disgraceful because it is the best that evolutionists have. (I already responded to it here.)
Let me emphasize again, evolutionists claimed for decades that Haldane's Dilemma was "solved". Therefore, the peer-reviewed literature ought display a solution that a majority of evolutionary geneticists back with their names and reputations, and that solution ought be firmly integrated into evolutionary theorizing. But no such solution exists. Instead, we have evolutionary geneticists hiding behind a non-peer-reviewed internet web-page written by a non-expert. It is a disgusting display of how science ought not be done. It is a scandal. Evolutionary geneticists should step-up and publish on Haldane's Dilemma.

Kryptid, you are falsely inserting young-earth issues into ReMine's book. You should start another thread for your speculations about young-earth.
[Note: The classic result, (neutral substitution rate = neutral mutation rate), is only valid for large genomes, such as mammals. But not for a virus, where Kimura's infinite-sites model is violated.]
