Grooming is a very important part of chimpanzee culture and serves to form alliances and strengthen bonds. The other night, there was a minor fight and Jamie got a couple of wounds on her foot and on her head. Missy is usually our most diligent groomer and often follows folks around trying to groom their injuries, which is exactly what she did for Jamie today. I suppose she could just be a clean-freak, or she could be strengthening her allies for the next conflict– it’s pretty smart either way.
