Sorry, don't understand. At best, morality is godshatter from genetic evolution. But that doesn't mean genetic evolution has produce recent (within 10k years) morally relevant changes.
There are some pretty reasonable arguments against this. Honestly I would be rather surprised if the genotypic distribution of say the tendency towards empathy or different kinds of altruism or tribalism or religiosity weren't significantly different among Sumerian farmers of 4000 BC compared to the Mongolian horsemen of 1400 AD or the petty bourgeois of England in 1850 AD.
It it is hard to argue that the distribution of such traits would not influence the fitness landscape of memeplexes claiming to systematize and correct such intuitions into a framework of "ethics".
I have found this most wonderful (if fairly lengthy) article, and thought you would enjoy having it brought to your attention.
It is so good, I think we should include it among the references in the "Politics is the Mind Killer" wiki page. But, before that, I submit it to you, and ask you: is there anything in this article that would warrant its exclusion from this site? I mean, besides the fact that it is about politics, and written by a notorious Social-democrat (And is that in itself grounds for exclusion?).
