🚨New paper alert! 🐵 We compared yawning in geladas vs hamadryas baboons and guess what? Differences in the sociobiology of the two species seem to be reflected in the expression of the behaviour OA here: onlinelibrary.wiley.com/doi/10.1002/...

L’empathie n’est pas le propre de l’humain : ces singes utilisent des signaux vocaux pour se réconforter

Une très récente étude démontre que des singes géladas d’Éthiopie savent faire preuve d’empathie en réconfortant leurs congénères par des signaux vocaux.

🚨New paper! We found that in rhesus macaques spontaneous triadic affiliation after conflicts is common, increases with the victim-bystander bond and victim distress signals. This challenges traditional despotic-tolerant dichotomies🐒 free to read here:
