Because of political instability in the region, and the general timidity of bonobos, there has been relatively little field work done observing the species in its natural habitat.Īccording to studies published in 2017 by researchers at The George Washington University, the ancestors of the genus Pan split from the human line about 8 million years ago moreover, bonobos split from the common chimpanzee line about 2 million years ago. The bonobo inhabits primary and secondary forest, including seasonally inundated swamp forest. The species is predominantly frugivorous, compared to the often highly omnivorous diets and hunting of small monkeys, duiker and other antelope exhibited by common chimpanzees. The bonobo is found in a 500,000 km 2 (190,000 sq mi) area within the Congo Basin of the Democratic Republic of the Congo (DRC), Central Africa. Some individuals have sparser, thin hair over parts of their bodies. īonobos are distinguished from common chimpanzees by relatively long limbs, pinker lips, a darker face, a tail-tuft through adulthood, and parted, longer hair on its head. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina-composed entirely by the genus Pan-are collectively termed panins. While bonobos are, today, recognized as a distinct species in their own right, they were initially thought to be a subspecies of Pan troglodytes, due to the physical similarities between the two species.
kadabba’s upright walking comes from an single toe bone that dates to 5.2 million years old and was found 10 miles away from the other Ar. kadabba routinely bipedal? So far, the evidence for Ar. We don’t know everything about early humans-but we keep learning more! Paleoanthropologists are constantly in the field, excavating new areas with groundbreaking technology, and continually filling in some of the gaps about our understanding of human evolution.īelow are some of the still unanswered questions about Ardipithecus kadabba that may be answered with future discoveries: Based on these teeth, paleoanthropologists Yohannes Haile-Selassie, Gen Suwa, and Tim White allocated the fossils in 2004 to a new species they named Ardipithecus kadabba (‘kadabba’ means ‘oldest ancestor’ in the Afar language). The dental wear patterns confirmed the early human fossils were unique and not a subspecies of A. In 2002, six teeth were discovered in the Middle Awash at the site Asa Koma. Faunal (fossil animal) evidence from the site indicated that the early humans there lived in a mixture of woodlands and grasslands, and had plenty of access to water via lakes and springs. One of the specimens, a toe bone, is dated to 5.2 million years old this fossil has features of bipedal walking. The fossils-which also included hand and foot bones, partial arm bones, and a clavicle (collarbone)-were dated to 5.6–5.8 million years old. But 11 specimens from at least 5 individuals later, Haile-Selassie was convinced he had found a new early human ancestor. When he found a piece of lower jaw lying on the ground in the Middle Awash region of Ethiopia 1997, paleoanthropologist Yohannes Haile-Selassie didn’t realize that he had uncovered a new species.
