The Catholic church prohibits cousin marriage and imposes restrictions on marrying goddaughters and divorce. This alters family structures and prevents the formation of powerful kinship bonds that could challenge the authority of the church. In societies where cousin marriage is prevalent, kin selection and inclusive fitness lead to stronger cooperation and the formation of interconnected family webs, fostering tribal relationships that could undermine centralized authority.
What makes humanity unique?
Dr. Michael Muthukrishna is fascinated by why our species behaves the way it does. In his book, A Theory of Everyone, Michael seeks to answer some of the deepest questions humans have about ourselves and how our cultures came to be. Why do humans create culture? What do all our societies have in common? And how can this knowledge help us build a better future?
This...is A Bit of Optimism.
In our conversation, Michael references a paper published in Science titled "The Church, intensive kinship, and global psychological variation." You can read it here.
