If hominins are indeed adapted to using complex topography as their primary habitat rather than as a refuge, we would not expect them to share many adaptations with either savannah baboons or the gelada.
Primate factsheets: gelada baboon (Theropithecus gelada) taxonomy, morphology and ecology.
Washington, April 9 ( ANI ): The vocal lip-smacks that gelada
monkeys use in friendly encounters have surprising similarities to human speech, a study has revealed.
Bill will also open the Black Country tourist attraction's Baboons on the Bank exhibit, a oneacre hillside grazing area for Gelada baboons.
Zoo head of media and communications Jill Hitchman said: "Bill will be officially opening our Baboons on the Bank enclosure which was constructed in-house by our development team and provides a natural hillside home for the five-strong Gelada group.
In studying wild geladas in the Simien Mountains National Park in Ethiopia, researchers identified the leader and follower males, noted the numbers of females in all units; tracked individuals involved in unit takeovers; and noted all new births.
Even though geladas primarily form single-male groups, researchers showed a benefit to forming multi-male groups.

De lá até os dias de hoje, outras evidências são obtidas através da observação das variações da cobertura de neve das montanhas e de áreas geladas

For the study, Thore Bergman, an assistant professor of psychology and ecology and evolutionary biology at the University of Michigan, looked at individual recognition in male geladas
, close relatives of baboons) that live in fluid, multilevel groups that can number more than 1,200 individuals - 10 times larger than baboon groups.
drift] is more pronounced in cycling than in running despite the greater thermal load, dehydration and increased heart rate of the subjects in the latter type of exercise (Nassis and Geladas
, 2002) suggesting that the active muscle mass plays a role.
Senior Curator Derek Grove, who headed the project, said: "We required a larger area for the Gelada
baboons when we had the opportunity to set up a new breeding group.
