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 plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hominid
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 (''Homo sapiens'') remain. Numerous revisions in classifying the great apes have caused the use of the term ''hominid'' to change over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans and other apes 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 scientis ...

Homininae
Homininae (the hominines) is a subfamily of the family Hominidae (hominids). (The Homininae——encompass humans, and are also called "African hominids" or "African apes".) This subfamily includes two tribes, Hominini and Gorillini, both having extant (or living) species as well as extinct species. Tribe Hominini includes: the extant genus ''Homo'', which comprises only one extant species—the modern humans (''Homo'' sapiens), and numerous extinct human species; and the extant genus '' Pan'', which includes two extant species, chimpanzees and bonobos. Tribe Gorillini (gorillas) contains one extant genus, Gorilla, with two extant species, with variants, and one known extinct genus. Alternatively, the genus ''Pan'' is considered by some to belong, instead of to a subtribe Panina, to its own separate tribe, (''so-called'') "Panini"—which would be a third tribe for Homininae. Some classification schemes provide a more comprehensive account of extinct groups—(see section "Taxo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Nakalipithecus
''Nakalipithecus nakayamai'', sometimes referred to as the Nakali ape, 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. The jawbone 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 ... [...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 adap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hominini
The Hominini (hominins) form a Tribe (biology), taxonomic tribe of the subfamily Homininae (hominines). They comprise two extant genera: ''Homo'' (humans) and ''Pan (genus), Pan'' (chimpanzees and bonobos), and in standard usage exclude the genus ''Gorilla (genus), Gorilla'' (gorillas), which is grouped separately within the subfamily Homininae. The term Hominini was originally introduced by Camille Arambourg (1948), who combined the categories of ''Hominina'' and ''Simiina'' pursuant to John Edward Gray, Gray's classifications (1825). Traditionally, chimpanzees, gorillas and orangutans were grouped together, excluding humans, as pongidae, pongids. Since Gray's classifications, evidence accumulating from genetic phylogeny confirmed that humans, chimpanzees, and gorillas are more closely related to each other than to the orangutan. The orangutans were reassigned to the family Hominidae (great apes), which already included humans; and the gorillas were grouped as a separate tr ...

Chimpanzee
The chimpanzee (; ''Pan troglodytes''), also simply known as the chimp, is a species of Hominidae, great ape native to the forests and savannahs of tropical Africa. It has four confirmed subspecies and a fifth proposed one. 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 (genus), ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the Human evolution, human lineage and is thus 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 grou ...

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. It was named after the Italian city of Tortona in the Piedmont region. The base of the Tortonian Stage is at the last common appearance of calcareous nanoplankton '' Discoaster kugleri'' and planktonic foram '' Globigerinoides subquadratus''. It is also associated with the short normal pol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonobo
The bonobo (; ''Pan paniscus''), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus ''Pan (genus), Pan'' (the other being the common chimpanzee, ''Pan troglodytes''). While bonobos are today recognized as a distinct species in their own right, they were initially thought to be a subspecies of ''Pan troglodytes'', because of the physical similarities between the two species. Taxonomically, members of the chimpanzee/bonobo subtribe Panina—composed entirely by the genus ''Pan (genus), Pan''—are collectively termed ''panins''. Bonobos are distinguished from common chimpanzees by relatively long limbs, pinker lips, a darker face, a tail-tuft through adulthood, and parted, longer hair on their heads. Some individuals have sparser, thin hair over parts of their bodies. The bonobo is found in a area within the Congo Basin of the Democratic Republic of the Con ...
