[Verginius Rufus]

Taboos against incest seem to be universal--it seems that all human societies know that too-close interbreeding is harmful. What this study suggests is that the pattern of the sons staying in the family abode while the daughters married out to another household was already found among these ancient hominids.

At a much more recent period, the Proto-Indo-European speakers seem to have had patriarchal families where the sons stayed put and the daughters married away--that is deduced from various words for family relationships in the later Indo-European languages.

Of course the marriage customs among the Paranthropi robusti would have differed in detail from later hominid species--they didn't throw rice since they didn't have rice.
