Homo (genus)
''Homo'' () is the genus that emerged in the (otherwise extinct) genus '' Australopithecus'' that encompasses the extant species ''Homo sapiens'' ( modern humans), plus several extinct species classified as either ancestral to or closely related to modern humans (depending on the species), most notably '' Homo erectus'' and '' Homo neanderthalensis''. The genus emerged with the appearance of '' Homo habilis'' just over 2 million years ago. ''Homo'', together with the genus '' Paranthropus'', is probably sister to '' Australopithecus africanus'', which itself had previously split from the lineage of '' Pan'', the chimpanzees. '' Homo erectus'' appeared about 2 million years ago and, in several early migrations, spread throughout Africa (where it is dubbed '' Homo ergaster'') and Eurasia. It was likely that the first human species lived in a hunter-gatherer society and was able to control fire. An adaptive and successful species, ''Homo erectus'' persisted for more than a mi ...

Homo Naledi
'' Homo naledi'' is an extinct species of archaic human discovered in 2013 in the Rising Star Cave, Cradle of Humankind, South Africa dating to the Middle Pleistocene 335,000–236,000 years ago. The initial discovery comprises 1,550 specimens, representing 737 different elements, and at least 15 different individuals. Despite this exceptionally high number of specimens, their classification with other ''Homo'' remains unclear. Along with similarities to contemporary ''Homo'', they share several characteristics with the ancestral ''Australopithecus'' and early ''Homo'' as well ( mosaic evolution), most notably a small cranial capacity of 465–610 cm3 (28.4–37.2 cu in), compared to 1,270–1,330 cm3 (78–81 cu in) in modern humans. They are estimated to have averaged in height and in weight, yielding a small encephalization quotient of 4.5. Nonetheless, ''H. naledi'' brain anatomy seems to have been similar to contemporary ''Homo'', which could indicate comparabl ...

Paranthropus
''Paranthropus'' is a genus of extinct hominin which contains two widely accepted species: '' P. robustus'' and '' P. boisei''. However, the validity of ''Paranthropus'' is contested, and it is sometimes considered to be synonymous with ''Australopithecus''. They are also referred to as the robust australopithecines. They lived between approximately 2.6 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. ''Paranthropus'' species were generalist feeders, but ''P. robustus'' was likely an omnivore, whereas ''P. boisei'' was likely herbivorous and mainly ate bulbotubers. They were bipeds. Despite their robust heads, they had comparatively small bodies. Average weight and heig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature (journal)
''Nature'' is a British weekly scientific journal founded and based in London, England.

LD 350-1
LD 350-1 is the earliest known specimen of the genus ''Homo'', dating to 2.8–2.75 million years ago (mya), found in the Ledi-Geraru site in the Afar Region of Ethiopia. The specimen was discovered in silts above the Gurumaha Tuff section of the site by Ethiopian palaeoanthropologist Chalachew Seyoum on 29 January 2013. It is currently unassigned to a species, and it is unclear if it represents the ancestor to ''H. habilis'' and ''H. rudolfensis'' which evolved around 2.4 mya. Description LD 350-1 is an adult left jawbone including the canine, both premolars, and all three molars. In terms of overall size, the specimen is within the range of what is seen in small ''Australopithecus afarensis'' specimens, and LD 350-1 seems to be a transitional form between ''Australopithecus'' and ''Homo''. However, the specimen's anatomy strongly diverges from australopithecines and more closely aligns with ''Homo'': the mental foramina are not located on a depression, it has a symphyseal keel ...

Ancestral
An ancestor, also known as a forefather, fore-elder or a forebear, is a parent or ( recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent and so forth). ''Ancestor'' is "any person from whom one is descended. In law, the person from whom an estate has been inherited." Two individuals have a genetic relationship if one is the ancestor of the other or if they share a common ancestor. In evolutionary theory, species which share an evolutionary ancestor are said to be of common descent. However, this concept of ancestry does not apply to some bacteria and other organisms capable of horizontal gene transfer. Some research suggests that the average person has twice as many female ancestors as male ancestors. This might have been due to the past prevalence of polygynous relations and female hypergamy. Assuming that all of an individual's ancestors are otherwise unrelated to each other, that individual has 2''n'' ancestors in the ...

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] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Homo Rudolfensis
''Homo rudolfensis'' is an extinct species of archaic human from the Early Pleistocene of East Africa about 2 million years ago (mya). Because ''H. rudolfensis'' coexisted with several other hominins, it is debated what specimens can be confidently assigned to this species beyond the lectotype skull KNM-ER 1470 and other partial skull aspects. No bodily remains are definitively assigned to ''H. rudolfensis''. Consequently, both its generic classification and validity are debated without any wide consensus, with some recommending the species to actually belong to the genus ''Australopithecus'' as ''A. rudolfensis'' or ''Kenyanthropus'' as ''K. rudolfensis'', or that it is synonymous with the contemporaneous and anatomically similar ''H. habilis''. ''H. rudolfensis'' is distinguished from ''H. habilis'' by larger size, but it is also argued that this species actually consists of male ''H. habilis'' specimens, assuming that ''H. habilis'' was sexually dimorphic and males were muc ...
