Eusociality is relevant. Developed & extended by AO Wilson, world leading social insect expert, and staunch opponent of 'selfish gene' reductionism. By the strict definition, humans have been eusocial, and language occured in that context - in tribal units.
Confucianism focuses on family way ahead of individuality, making 'filial piety' a primary social value for order & harmony in society. In modern thought this seems repressive, but succession crisees have been a majorly destabilising & destructive force through most of human history, is a big focus of the Maharabata, & many other cultural narratives, & is still hugely problematic in Subsaharan Africa where only a few peaceful transitions of power have been made (& Trump is trying to undermine the democratic tradition's solution, like Caesar undermined Rome's that the US is based on). I would say Confucianism has a countervailing picture of the origin of society, to social contract theory.
I remember reading about a comparison of locus of control/accountability between West & East (as including India) - I wonder how much that is about the role of extended families and the domination of politics by successful ones, vs post-industrial family atomisation as people moved for work. I think I don't have the terminology right, because I haven't been able to track it down.
Burke's 'social contract for the ages', or between generations, sounds like other contract theories, but links past & present groups to duties to the future, which may be relevant.
