Things such as Haldane's dilemma are relevant to the thread. I would ask for participants of the thread to have benefitial mutations as a given. There is a thread of that already.
​
Unless selection is very intense the number of deaths needed to secure the substitution by natural selection, of one gene for another at a locus, is independent of the intensity of selection. It is often about 30 times the number of organisms in a generation. It is suggested that in horoletic evolution, the mean time taken for each gene substitution is about 300 generations. This accords with the observed slowness of evolution.

Creationists like ReMine say that it refutes evolution.
This paper is very old and even Haldane admitted that there might be errors in his calculations.
​
If Haldane was wrong then what model was able to correct it?

Fixation is related to alleles, not features.

Ok I fixed my mistake.
​
Another thing to note, is that it may only apply to mammaks since they reproduce slowly.
