The paper examines group fission in geladas, finding that females join new groups with kin and allies, and that fission reduces infanticide risk.

The paper quantifies variation in primate social structures across 11 species, identifying distinct patterns in kin and rank biases and male-centered subgrouping.

This study identifies genomic and karyotypic changes in geladas that may contribute to high-altitude adaptation and speciation.
