How orangutan engineers build safe and comfortable treetop beds

Chimpanzee behavior suggests tree-to-ground transition occurred before emergence of ancient humans The first study into rarely documented ground-nest building by wild chimpanzees offers new clues about the ancient transition of early hominins from sleeping in trees to sleeping on the ground. While most apes build nests in trees, this study, published in the American Journal of Physical Anthropology, focused on a group of wild West African chimpanzees that often shows ground-nesting behavior. An international team of primatologists from the University of Cambridge and Kyoto University, led by Dr Kathelijne Koops, studied the chimpanzee (Pan troglodytes verus) population in the Nimba Mountains in Guinea, West Africa. All species of great ape build nests to sleep in each night. Construction of these shelters takes minutes as the apes bend, break and interweave branches into a circular frame, followed by tucking in smaller branches to form a sturdy but comfortable sleeping platform. "We believe that, like modern
