CAN YOU TELL IF TWO CHIMPANZEES ARE RELATED JUST BY LOOKING AT THEIR PHOTOS?

In our experiment, hosted by Gorilla.sc, you will see a photo of a chimpanzee and four possible matches. Can you tell who is related to who? Mothers, fathers, brothers, sisters – they’re all there! Humans can recognise biological relatives through facial features; we want to explore how kin-based facial recognition evolved in humans and other primates.

DATA COLLECTION NOW FINISHED – THANK YOU!
