Very interesting article that.
However, evolution is able to test and spread many genes at the same time, thus achieving higher efficiency than the article suggests. Sort of like spread spectrum radio.
I am quite certain its speed is lower than some statistical methods, but not by that much.
I guess at something like a constant factor slower, for doubling gene concentration, as compared to 1 std deviation certainty for the goodness of the gene by Gaussian statistics.
Random binary natural testing of a gene is less accurate than statistics, but it avoids putting counters in the cells for each gene, thus shrinking the cellular machinery necessary for this sort of inference, thus increasing the statistical power per base pair. And I know there are more complicated methods in use for some genes, such as anti bodies, methylation, etc.
And then there is sexual selection, where the organisms use their brains to choose partners. This is even closer to evolution assisted by Bayesian super intelligence.
So I guess that evolutions is not so slow after all.
We can see that intelligent design beats random mutations by quite a stretch - by looking at the acceleration of change due to cultural evolution and technology.
Of course cultural evolution is still a kind of evolution - but intelligent mutations, multi-partner recombination and all the other differences do seem to add up to something pretty substantial.
