Hominins
The Hominini (hominins) form a taxonomic tribe of the subfamily Homininae (hominines). They comprise two extant genera: ''Homo'' (humans) and '' Pan'' (chimpanzees and bonobos), and in standard usage exclude the 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 Gray's classifications (1825). Traditionally, chimpanzees, gorillas and orangutans were grouped together, excluding humans, as 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 tribe (Gorillini) of the subfamily Homininae. Still, details of this re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo
''Homo'' () is a genus of great ape (family Hominidae) that emerged from the genus ''Australopithecus'' and encompasses only a single extant species, ''Homo sapiens'' (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include ''Homo erectus'' and ''Homo neanderthalensis''. The oldest member of the genus is ''Homo habilis'', with records of just over 2 million years ago. ''Homo'', together with the genus ''Paranthropus'', is probably most closely related to the species ''Australopithecus africanus'' within ''Australopithecus''.'''' The closest living relatives of ''Homo'' are of the genus ''Pan (genus), Pan'' (chimpanzees and bonobos), with the ancestors of ''Pan'' and ''Homo'' estimated to have diverged around 5.7–11 million years ago during the Late Miocene. ''H. erectus'' appeared about 2 million years ago and spread throughout Africa (deba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kenyanthropus
''Kenyanthropus'' is a genus of extinct hominin identified from the Lomekwi site by Lake Turkana, Kenya, dated to 3.3 to 3.2 million years ago during the Middle Pliocene. It contains one species, ''K. platyops'', but may also include the 2 million year old '' Homo rudolfensis'', or ''K. rudolfensis''. Before its naming in 2001, ''Australopithecus afarensis'' was widely regarded as the only australopithecine to exist during the Middle Pliocene, but ''Kenyanthropus'' evinces a greater diversity than once acknowledged. ''Kenyanthropus'' is most recognisable by an unusually flat face and small teeth for such an early hominin, with values on the extremes or beyond the range of variation for australopithecines in regard to these features. Multiple australopithecine species may have coexisted by foraging for different food items ( niche partitioning), which may be reason why these apes anatomically differ in features related to chewing. The Lomekwi site also yielded the earliest sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Human
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are Hominidae, great apes characterized by their Prehistory of nakedness and clothing#Evolution of hairlessness, hairlessness, bipedality, bipedalism, and high Human intelligence, intelligence. Humans have large Human brain, brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are Sociality, highly social, with individual humans tending to belong to a Level of analysis, multi-layered network of distinct social groups — from families and peer groups to corporations and State (polity), political states. As such, social interactions between humans have established a wide variety of Value theory, values, norm (sociology), social norms, languages, and traditions (co ...

Sahelanthropus
''Sahelanthropus'' is an extinct genus of hominid dated to about during the Late Miocene. The type species, ''Sahelanthropus tchadensis'', was first announced in 2002, based mainly on a partial cranium, nicknamed ''Toumaï'', discovered in northern Chad. The definitive phylogenetic position of ''Sahelanthropus'' within hominids is uncertain. It was initially described as a possible hominin ancestral to both humans and chimpanzees, but subsequent interpretations suggest that it could be an early member of the tribe Gorillini or a stem-hominid outside the hominins. Examinations on the postcranial skeleton of ''Sahelanthropus'' also indicated that this taxon was not a habitual biped.

Australopithecus
''Australopithecus'' (, ; or (, ) is a genus of early hominins that existed in Africa during the Pliocene and Early Pleistocene. The genera ''Homo'' (which includes modern humans), ''Paranthropus'', and ''Kenyanthropus'' evolved from some ''Australopithecus'' species. ''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 ''Australopithecus garhi, A. garhi'', ''Australopithecus africanus, A. africanus'', ''Australopithecus sediba, A. sediba'', ''Australopithecus afarensis, A. afarensis'', ''Australopithecus anamensis, A. anamensis'', ''Australopithecus bahrelghazali, A. bahrelghazali'', and ''Australopithecus deyiremeda, A. deyiremeda''. Debate exists as to whether some ''Australopithecus'' species should be reclassified into new genera, or if ''Paranthropus'' and ''Kenyanthropus'' are synonymous with ...

Graecopithecus
''Graecopithecus'' is an extinct genus of hominid that lived in southeast Europe during the late Miocene around 7.2 million years ago. Originally identified by a single lower jawbone bearing teeth found in Pyrgos Vasilissis, Athens, Greece, in 1944, other teeth were discovered from Azmaka quarry in Bulgaria in 2012. With only little and badly preserved materials to reveal its nature, it is considered as "the most poorly known European Miocene hominoids." The creature was popularly nicknamed 'El Graeco' (word play on the Greek-Spanish painter El Greco) by scientists. In 2017, an international team of palaeontologists led by Madelaine Böhme of the Eberhard-Karls-University Tübingen, Germany, published a controversial analysis of the teeth and age of the specimens, and came to the conclusion that it could be the oldest hominin, meaning that it could be the oldest direct ancestors of humans after splitting from that of the chimpanzees. Their simultaneous study also claimed tha ... [...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] |
Paranthropus
''Paranthropus'' is a genus of extinct hominin which contains two widely accepted species: ''Paranthropus robustus, P. robustus'' and ''P. boisei''. However, the validity of ''Paranthropus'' is contested, and it is sometimes considered to be synonym (taxonomy), synonymous with ''Australopithecus''. They are also referred to as the robust australopithecines. They lived between approximately 2.9 and 1.2 million years ago (mya) from the end of the Pliocene to the Middle Pleistocene. ''Paranthropus'' is characterised by robust skulls, with a prominent gorilla-like sagittal crest along the midline—which suggest strong chewing muscles—and broad, herbivorous teeth used for grinding. However, they likely preferred soft food over tough and hard food. Typically, ''Paranthropus'' species were generalist feeders, but while ''P. robustus'' was likely an omnivore, ''P. boisei'' seems to have been herbivorous, possibly preferring abundant bulbotubers. Paranthropoids were bipeds. Despite th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australopithecina
The australopithecines (), formally Australopithecina or Hominina, are generally any species in the related genera of ''Australopithecus'' and ''Paranthropus''. It may also include members of '' Kenyanthropus'', ''Ardipithecus'', and '' Praeanthropus''. The term comes from a former classification as members of a distinct subfamily, the Australopithecinae. They are classified within the Australopithecina subtribe of the Hominini tribe. These related species are sometimes collectively termed australopithecines, australopiths, or homininians. They are the extinct, close relatives of modern humans and, together with the extant genus ''Homo'', comprise the human clade. There is no general agreement to whether australopithecines are closest relatives of modern humans, as it has been argued that they are more closely related to extant African apes. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are called Hominina (''see Hominidae; terms "hominids" ...

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 (''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 ...
