Genital mutilation/cutting is associated with the presence of co-wives living separately.


This is tested for each form of GM/C, and is included in all of the models, showing that co-wives living separately is associated with every form of GM/C. Correlated evolution models show that all types of GM/C are more likely to evolve in societies in which co-wives reside separately.
