S2 Social rank, age peers, and social partners among groupmates of individual female savannah baboons involved in fissions of permanent social groups. ‘Pre-‘ and ‘Post-‘ values are those observed before and after the fissions. ‘Exp’ values are the post-fission values expected after random fission. ‘ID’ identifies each female. ‘Genotyped’ indicates whether she was genotyped. ‘Startgroup’ is her pre-fission social group, and ‘Endgroup’ is the group she joined after her original social group divided. ‘NA’ indicates that data were not available.
