this is obviously an over-simplification, but i wanted to outline some of the effects that inbreeding and outbreeding have on social behaviors. so, it’s way, waaaay over-simplified. it’s just me thinking out loud.

these are just a few of my favorite things i thought of off the top of my head. there’ve been many others discussed around here lately — like harmonious jim suggested that exogamy lead to humanism. i think that’s prolly pretty right. we wouldn’t have gotten here without strong exogamy anyway.

also, there ought to be more gradations here, but i didn’t bother right now — like somewhere in between “no inbreeding” (nuclear families) and “maternal-side inbreeding” (clans) there ought to be extended families — not completely outbred, but not as inbred as clan-based societies. (maternal-side inbreeding = mbd & mzd marriage; paternal-side inbreeding = fbd & fzd marriage.)

anyway — here is a rough guide to some of the apparent effects of inbreeding and outbreeding on social behaviors. do, please, suggest some more! (and/or take issue with these!):
