Chororapithecus
''Chororapithecus'' is an extinct great ape from the Afar region of Ethiopia roughly 8 million years ago during the Late Miocene, comprising one species, ''C. abyssinicus''. It is known from 9 isolated teeth discovered in a 2005–2007 survey of the Chorora Formation. The teeth are indistinguishable from those of gorillas in terms of absolute size and relative proportions, and it has been proposed to be an early member of Gorillini. However, this is controversial given the paucity of remains, and notable anatomical differences between ''Chororapithecus'' and gorilla teeth. The Kenyan ape ''Nakalipithecus'' has been proposed to be an ancestor of ''Chororapithecus'' or at least closely related. If correct, they would be the only identified fossil members of any modern non-human great ape lineage, and would push the gorilla–human last common ancestor from 8 million years ago (identified by molecular analysis) to 10 million years ago. The teeth are adapted for processing tough plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Ape
The Hominidae (), whose members are known as the great apes or hominids (), are a taxonomic family of primates that includes eight extant species in four genera: '' Pongo'' (the Bornean, Sumatran and Tapanuli orangutan); ''Gorilla'' (the eastern and western gorilla); '' Pan'' (the chimpanzee and the bonobo); and ''Homo'', of which only modern humans remain. Several revisions in classifying the great apes have caused the use of the term ''"hominid"'' to vary over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans, apes, and their ancestors were considered to be "hominids". The earlier restrictive meaning has now been largely assumed by the term ''" hominin"'', which comprises all members of the human clade after the split from the chimpanzees (''Pan''). The current meaning of "hominid" includes all the great apes including humans. Usage still varies, however, and some scientists an ...

Homininae
Homininae (), also called "African hominids" or "African apes", is a subfamily of Hominidae. It includes two tribes, with their extant as well as extinct species: 1) the tribe Hominini (with the genus ''Homo'' including modern humans and numerous extinct species; the subtribe Hominina, comprising at least two extinct genera; and the subtribe Panina, represented only by the genus ''Pan'', which includes chimpanzees and bonobos)―and 2) the tribe Gorillini (gorillas). Alternatively, the genus '' Pan'' is sometimes considered to belong to its own third tribe, Panini. Homininae comprises all hominids that arose after orangutans (subfamily Ponginae) split from the line of great apes. The Homininae cladogram has three main branches, which lead to gorillas (through the tribe Gorillini), and to humans and chimpanzees via the tribe Hominini and subtribes Hominina and Panina (see the evolutionary tree below). There are two living species of Panina (chimpanzees and bonobos) and two livin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nakalipithecus
''Nakalipithecus nakayamai'' is an extinct species of great ape from Nakali, Kenya, from about 9.9–9.8 million years ago during the Late Miocene. It is known from a right jawbone with 3 molars and from 11 isolated teeth, and the specimen is presumed female as the teeth are similar in size to those of female gorillas and orangutans. Compared to other great apes, the canines are short, the enamel is thin, and the molars are flatter. ''Nakalipithecus'' seems to have inhabited a sclerophyllous woodland environment. Taxonomy ''Nakalipithecus'' was first described from a right jawbone, the holotype KNM-NA46400, and eleven isolated teeth excavated in 2005 by a team of Japanese and Kenyan researchers in mud flow deposits in the Nakali area of northern Kenya's former Rift Valley Province, hence the genus name ''Nakalipithecus'' ("Nakali ape"). The species name is in honour of the late Japanese geologist Katsuhiro Nakayama who worked on the expedition. The specimen dates to about 9.9 ...

Gen Suwa
Gen Suwa (born 1954) is a Japanese paleoanthropologist. He is known for his contributions to the understanding of the evolution of early hominids, including the discovery of a tooth from a hominid that was more than one million years older than the oldest previously known hominid. The discovery changed scientific opinion regarding the ancestral splits between humans, chimps and gorillas. A professor at The University Museum of the University of Tokyo, Suwa is a foreign associate of the National Academy of Sciences and a recipient of the Asahi Prize. Biography Suwa completed an undergraduate degree in biology from the University of Tokyo, and he earned a master's degree in biological anthropology from the same institution in 1980. He earned a Ph.D. in anthropology at the University of California, Berkeley. He began to study hominid fossils in Ethiopia during his doctoral studies. He worked with Berkeley anthropology professor Tim D. White and has continued to collaborate with him a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kenyapithecus
''Kenyapithecus wickeri'' is a fossil ape discovered by Louis Leakey in 1961 at a site called Fort Ternan in Kenya. The upper jaw and teeth were dated to 14 million years ago. One theory states that ''Kenyapithecus'' may be the common ancestor of all the great apes. More recent investigations suggest ''Kenyapithecus'' is more primitive than that and is only slightly more modern than ''Proconsul'', which is considered to be an ape. Evidence suggests that ''Kenyapithecus wickeri'' was one of the species that started a radiation of apes out of Africa. Morphology Impressed by ''Kenyapithecus''s modern-looking teeth, Leakey declared ''Kenyapithecus'' to be "a very early ancestor of man himself." ''Kenyapithecus'' possessed craniodental adaptations for hard object feeding including thicker molar enamel, and a large mandible, large premolars and upper incisors that are similar to those seen in living pitheciine monkeys. ''Kenyapithecus'' also possessed macaque-like limbs ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ardipithecus
''Ardipithecus'' is a genus of an extinct hominine that lived during the Late Miocene and Early Pliocene epochs in the Afar Depression, Ethiopia. Originally described as one of the earliest ancestors of humans after they diverged from the chimpanzees, the relation of this genus to human ancestors and whether it is a hominin is now a matter of debate. Two fossil species are described in the literature: '' A. ramidus'', which lived about 4.4 million years ago during the early Pliocene, and '' A. kadabba'', dated to approximately 5.6 million years ago (late Miocene). Initial behavioral analysis indicated that ''Ardipithecus'' could be very similar to chimpanzees, however more recent analysis based on canine size and lack of canine sexual dimorphism indicates that ''Ardipithecus'' was characterised by reduced aggression, and that they more closely resemble bonobos. Some analyses describe ''Australopithecus'' as being sister to ''Ardipithecus ramidus'' specifically. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimpanzee
The chimpanzee (''Pan troglodytes''), also known as simply the chimp, is a species of great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing for males and for females and standing . The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives in ...

Bonobo
The bonobo (; ''Pan paniscus''), also historically called the pygmy chimpanzee and less often the dwarf chimpanzee or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus '' Pan,'' the other being the common chimpanzee (''Pan troglodytes''). While bonobos are now recognized as a distinct species in their own right, they were initially thought to be a subspecies of chimpanzee (''Pan troglodytes)'' due to the physical similarities between the two species. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina (composed entirely by the genus '' Pan'') are collectively termed ''panins''. The bonobo is distinguished by relatively long legs, pink lips, dark face, tail-tuft through adulthood, and parted long hair on its head. The bonobo is found in a area of the Congo Basin in the Democratic Republic of the Congo, Central Africa. The species is frugivorous and inhabits primary and secondary forests, including seasonally inundated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortonian
The Tortonian is in the geologic time scale an age or stage of the late Miocene that spans the time between 11.608 ± 0.005 Ma and 7.246 ± 0.005 Ma (million years ago). It follows the Serravallian and is followed by the Messinian. The Tortonian roughly overlaps with the regional Pannonian Stage of the Paratethys timescale of Central Europe. It also overlaps the upper Astaracian, Vallesian and lower Turolian European land mammal ages, the upper Clarendonian and lower Hemphillian North American land mammal ages and the upper Chasicoan and lower Huayquerian South American land mammal ages. Definition The Tortonian was introduced by Swiss stratigrapher Karl Mayer-Eymar in 1858.

Australopithecus
''Australopithecus'' (, ; ) is a genus of early hominins that existed in Africa during the Late Pliocene and Early Pleistocene. The genus ''Homo'' (which includes modern humans) emerged within ''Australopithecus'', as sister to e.g. ''Australopithecus sediba''. Also the genera '' Paranthropus'' and ''Kenyanthropus'' emerged within ''Australopithecus''. ''Australopithecus'' is a member of the subtribe Australopithecina, which sometimes also includes ''Ardipithecus'', though the term "australopithecine" is sometimes used to refer only to members of ''Australopithecus''. Species include '' A. garhi'', '' A. africanus'', '' A. sediba'', '' A. afarensis, A. anamensis, A. bahrelghazali'' and '' A. deyiremeda''. Debate exists as to whether some ''Australopithecus'' species should be reclassified into new genera, or if ''Paranthropus'' and ''Kenyanthropus'' are synonymous with ''Australopithecus'', in part because of the taxonomic inconsistency. The earliest known member of the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
