Hypothesis
There will be a co-evolution between Pama-Nyungan grandparent systems and community marriage organization.
Note
Community marriage organization did not have a significant impact on grandparental systems (pMCMC = 0.928). There was no indication of a correlation between linguistic exogamy and any specific aspect of grandparental systems in all 75 languages.
