How is the Ardipithecus lineage related the Australopithecus lineage?. kadabba somehow related to Orrorin tugenensis and Sahelanthropus tchadensis, two earlier human species? 
DId bipedalism independently develop in the Ardipithecus lineage? Or is Ar. kadabba walked upright, what was its gait like? 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. If competing against each other, a gorilla can kill a chimpanzee with its better teeth and strength. Gorillas are gentle while chimps can even kill their community members and humans too. However, chimpanzees are considered to be more aggressive than a gorilla. 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. They are far stronger and huge and also have bigger and better teeth than chimpanzees. One of the specimens, a toe bone, is dated to 5.2 million years old this fossil has features of bipedal walking. They are much smaller than the Central chimpanzee (P. 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. Western chimpanzees are intermediaries in size between other subspecies of chimpanzee. 
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.

The apes would be engaging in way more copulation, de Waal said, which brings up another problem: None of the primates in the movie have visible genitals.Smithsonian National Museum of Natural History The Smithsonian Institution's Human Origins Program Main Menu In real life, there would be a lot of monkey business going on. In the movie, the apes sit around looking stoic, weighing the costs and benefits of war. The teeth are large and square-like in the front with two sharper. There is a reason "Dawn of the Planet of the Apes" is rated PG-13. Discover what a chimpanzee looks like, and review additional facts about chimpanzees. "I would say 10 men could not hold down a chimp if it did not want to be held down." "Their arm strength is incredible, they have feet that act like arms and they have teeth," de Waal said. Their bodies, however, are probably their most potent weapon. Instead of huge weapons meant for taking down humans, they are more like sharpened sticks meant for stabbing bush babies - tiny, adorable primates that chimpanzees love to eat.Ĭhimps also regularly throw things like rocks and feces, de Waal said. A spear? It's actually something that chimps use - well, on a smaller scale. Chimpanzees in a captive group, living in seminaturalistic surroundings, clean and extract their own and each other’s teeth. In the movie, the primates are armed with everything from menacing spears to automatic rifles.
