…what sort of selection pressures for, say, behavioral traits and iq existed under the manoralism system in medieval europe versus the earlier tribal system? (obviously these are pretty broad categories that changed in nature quite a bit over time and between places, but still….) i’m thinking along the lines of “The 10,000 Year Explosion” in which (duh!) human evolution is ongoing and, like in the case of ashkenazi jews in europe, what happened during the medieval period was obviously important.
so, what happened to the germanic peoples during the middle ages evolutionarily speaking? anything? nothing? a lot?
in a tribal system, you’d think that within any given clan or tribe, most or all of the members would be kinda-sorta taken care of since everyone is family. you’d think that a lot of the members, therefore, would be able to leave at least some descendants behind. obviously, the chief of a clan might be able to leave behind the mostest descendants of all, but might it be that in a tribal system, more of the members might be reproductively successful than maybe…
…in the manoralism system, where the extended family system is gone and we’re left with pretty much just nuclear families operating in a corporate sort of world. in the manor system, there were different classes of peasants/laborers from free tenants to slaves (again, depending on when and where you’re talking about). but, clearly, those more able to succeed under the manor system prolly left behind more descendants than some others (’cause they were more fit to that environment, no?). so, those able to work their way up to and maintain the status of peasant or free tenant presumably were the most successful reproductively (after the lords, of course).
given that these peasants had to work their own land as well as do a lot of work on the manor — and given that many of them settled and opened up new territories in eastern europe (in which to farm the new grains with the new techniques) — what traits might have served the successful ones well?
obviously, you couldn’t be too dumb. maybe even practical, 3-d rotation intelligence would be good to have for engineering drainage systems and the like. i’d say that personality traits like hard-working and industriousness would also be selected for. i guess that might sorta be conscientiousness in a way, but not exactly. law abiding? conformity? i.e. not rocking the manoralism boat too much?
i also think in this new, non-tribal corporate world, whatever “genes for reciprocal altruism” might exist would prolly be selected for at greater rates than in a tribal society ’cause in the latter, kin selection altruism should be enough to keep things ticking along amicably. but not in a society where people are not so closely related.
anything else? any of this sound completely far out?
