Homo
''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 Erectus
''Homo erectus'' (; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Several human species, such as '' H. heidelbergensis'' and '' H. antecessor'' — with the former generally considered to have been the ancestor to Neanderthals, Denisovans, and modern humans — appear to have evolved from ''H. erectus''. Its specimens are among the first recognizable members of the genus ''Homo''. ''H. erectus'' was the first human ancestor to spread throughout Eurasia, with a continental range extending from the Iberian Peninsula to Java. Asian populations of ''H. erectus'' may be ancestral to '' H. floresiensis'' and possibly to '' H. luzonensis''. The last known population of ''H. erectus'' is '' H. e. soloensis'' from Java, around 117,000–108,000 years ago. ''H. erectus'' had a more modern gait and body proportions, and was the first human species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Ergaster
''Homo ergaster'' is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene. Whether ''H. ergaster'' constitutes a species of its own or should be subsumed into '' H. erectus'' is an ongoing and unresolved dispute within palaeoanthropology. Proponents of synonymisation typically designate ''H. ergaster'' as "African ''Homo erectus''" or "''Homo erectus ergaster''". The name ''Homo ergaster'' roughly translates to " working man", a reference to the more advanced tools used by the species in comparison to those of their ancestors. The fossil range of ''H. ergaster'' mainly covers the period of 1.7 to 1.4 million years ago, though a broader time range is possible. Though fossils are known from across East and Southern Africa, most ''H. ergaster'' fossils have been found along the shores of Lake Turkana in Kenya. There are later African fossils, some younger than 1 million years ago, that indicate long-term anatomical continuity, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Homo Habilis
''Homo habilis'' ("handy man") is an extinct species of archaic human from the Early Pleistocene of East and South Africa about 2.31 million years ago to 1.65 million years ago (mya). Upon species description in 1964, ''H. habilis'' was highly contested, with many researchers recommending it be synonymised with ''Australopithecus africanus'', the only other early hominin known at the time, but ''H. habilis'' received more recognition as time went on and more relevant discoveries were made. By the 1980s, ''H. habilis'' was proposed to have been a human ancestor, directly evolving into ''Homo erectus'' which directly led to modern humans. This viewpoint is now debated. Several specimens with insecure species identification were assigned to ''H. habilis'', leading to arguments for splitting, namely into "''H. rudolfensis''" and "'' H. gautengensis''" of which only the former has received wide support. Like contemporary ''Homo'', ''H. habilis'' brain size generally varied from . Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Floresiensis
''Homo floresiensis'' also known as "Flores Man"; nicknamed "Hobbit") is an extinct species of small archaic human that inhabited the island of Flores, Indonesia, until the arrival of modern humans about 50,000 years ago. The remains of an individual who would have stood about in height were discovered in 2003 at Liang Bua on the island of Flores in Indonesia. Partial skeletons of at least nine individuals have been recovered, including one complete skull, referred to as "LB1". These remains have been the subject of intense research to determine whether they were diseased modern humans or a separate species; a 2017 study concludes by phylogenetic analysis that ''H. floresiensis'' is an early species of ''Homo'', a sister species of ''Homo habilis''. This hominin was at first considered remarkable for its survival until relatively recent times, initially thought to be only 12,000 years ago. However, more extensive stratigraphic and chronological work has pushed the dating of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Homo Neanderthalensis
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor '' H. heidelbergensis'' is also unclear. The oldest potential Neanderthal bones date to 430,000 years ago, but the classification ...

Homo Heidelbergensis
''Homo heidelbergensis'' (also ''H. sapiens heidelbergensis''), sometimes called Heidelbergs, is an extinct species or subspecies of archaic human which existed during the Middle Pleistocene. It was subsumed as a subspecies of '' H. erectus'' in 1950 as ''H. e. heidelbergensis'', but towards the end of the century, it was more widely classified as its own species. It is debated whether or not to constrain ''H. heidelbergensis'' to only Europe or to also include African and Asian specimens, and this is further confounded by the type specimen (Mauer 1) being a jawbone, because jawbones feature few diagnostic traits and are generally missing among Middle Pleistocene specimens. Thus, it is debated if some of these specimens could be split off into their own species or a subspecies of ''H. erectus''. Because the classification is so disputed, the Middle Pleistocene is often called the "muddle in the middle." ''H. heidelbergensis'' is regarded as a chronospecies, evolving from an Afr ...

Homo Sapiens
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically ...

Homo Bodoensis
''Homo bodoensis'' is the species name for extinct archaic humans that lived during the Chibanian (770–126 ka) in Africa. It relies on the fossil specimen known as Bodo cranium, which was discovered in 1976 from the Awash River in Ethiopia and is estimated to have lived around 500,000 years ago. Following the comparative analysis of the fossil with those of other ''Homo'' falling on the same geological age, the name was formally introduced in 2021. Based on the confusing usage of scientific names for different hominin specimens of the Chibanian, a research team led by Mirjana Roksandic at the University of Winnipeg, Canada, proposed in '' Evolutionary Anthropology'' that ''H. bodoensis'' should be used as an umbrella name for all species of the same age in Africa, including '' H. rhodesiensis'' and '' H. heidelbergensis.'' But not all scientists agree. British paleoanthropologist Chris Stringer argued that the name cannot replace '' H. rhodesiensis'' to which Bodo cranium i ...
