Ronan Donovan Instagram – Here is Moon and Mususu again, wild chimpanzees, having a little group feeding experience in a fig tree. This behavior is referenced in my previous post as ‘wadging’ and it’s basically the process of turning fruits into pulp; sucking the juice out and then discarding the dry remains of the fruit in a ‘wadge’. Moon is the 3 year old son to Mususu and he’s taking advantage of his mother’s strong chewing muscles. All apes, except humans, have a tall ridge on the top of their skull called a sagittal crest. This ridge of bone provides an attachment point for tendons which allow powerful jaw muscles greater leverage in chewing fibrous plant matter. Wild chimps can spend upwards of 8 hours chewing a day – something humans avoid by cooking our food and therefore we lost out sagittal crest over the evolutionary timescale. ⁣ ⁣ Learn more about chimps in the current issue of @natgeo magazine, through my posts here and by following the conservation NGO @bulindichimps ⁣⁣ .⁣⁣ .⁣⁣⁣⁣ .⁣⁣⁣⁣ .⁣⁣⁣⁣ .⁣⁣⁣⁣ #chimpanzee #chimp #chimpanzees #chimps #ape #wildlife #conservation #animals #africa #uganda #bulindi #bulindichimps #wildlifephotography #nature #natgeo⁣⁣⁣ Uganda
