Koobi Fora
Koobi Fora refers primarily to a region around Koobi Fora Ridge, located on the eastern shore of Lake Turkana in the territory of the nomadic Gabbra people. According to the National Museums of Kenya, the name comes from the Gabbra language: The ridge itself is an outcrop of mainly Pliocene/Pleistocene sediments. It is composed of claystones, siltstones, and sandstones that preserve numerous fossils of terrestrial mammals, including early hominin species. Presently, the ridge is being eroded into a badlands terrain by a series of ephemeral rivers that drain into the northeast portion of modern Lake Turkana. In 1968 Richard Leakey established the Koobi Fora Base Camp on a large sandspit projecting into the lake near the ridge, which he called the Koobi Fora Spit. Consequently, the government of Kenya in 1973 reserved the region as Sibiloi National Park, establishing a headquarters for the National Museums of Kenya on Koobi Fora Spit. The reserve is well-maintained and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

KNM-ER 406
KNM ER 406 is an almost complete fossilized skull of the species ''Paranthropus boisei''. It was discovered in Koobi Fora, Kenya by Richard Leakey and H. Mutua in 1969. This species is grouped with the '' Australopitecine'' genus, ''Paranthropus boisei'' because of the robusticity of the skull and the prominent characteristics. This species was found well preserved with a complete cranium but lacking dentition. He was known for his robust cranial features that showed the signs of adaptation of the ecological niches. The big chewing muscles attached to the sagittal crest are traits of this adaptation. Discovery and classification Following a three-month expedition funded by the National Museums of Kenya, Richard Leakey and H. Mutua spent the summer of 1969 in northern Kenya. This expedition along with the field work three months prior to this project was possible with the financial assistance from the Kenyan Government. During this expedition, there were two specimens that have s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paranthropus Boisei
''Paranthropus boisei'' is a species of australopithecine from the Early Pleistocene of East Africa about 2.5 to 1.15 million years ago. The holotype specimen, OH 5, was discovered by palaeoanthropologist Mary Leakey in 1959 at Olduvai Gorge, Tanzania and described by her husband Louis a month later. It was originally placed into its own genus as "''Zinjanthropus boisei''", but is now relegated to ''Paranthropus'' along with other robust australopithecines. However, it is also argued that ''Paranthropus'' is an invalid grouping and synonymous with ''Australopithecus'', so the species is also often classified as ''Australopithecus boisei''. Robust australopithecines are characterised by heavily built skulls capable of producing high stresses and bite forces, and some of the largest molars with the thickest enamel of any known ape. ''P. boisei'' is the most robust of this group. Brain size was about , similar to other australopithecines. Some skulls are markedly smaller than ot ...

Australopithecus Anamensis
''Australopithecus anamensis'' is a hominin species that lived roughly between 4.3 and 3.8 million years ago, and is the oldest known ''Australopithecus'' species, Nearly 100 fossil specimens of ''A. anamensis'' are known from Kenya and Ethiopia, representing over 20 individuals. The first fossils of ''A. anamensis'' discovered are dated to around 3.8 and 4.2 million years ago and were found in Kanapoi and Allia Bay in northern Kenya. '' A. afarensis'' is normally accepted to have emerged within this lineage. However, ''A. anamensis'' and ''A. afarensis'' appear to have lived side-by-side for at least some period of time, and whether the lineage that led to extant humans emerged in ''A. afarensis'', or directly in ''A. anamensis'' is not fully settled. Fossil evidence determines that ''Australopithecus anamensis'' is the earliest hominin species in the Turkana Basin, but likely co-existed with ''afarensis'' towards the end of its existence. ''A. anamensis'' and ''A. afarensis'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Homo (genus)
''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'' ( 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 (debatably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Kamoya Kimeu
Kamoya Kimeu (1938 – 20 July 2022) was a Kenyan paleontologist and curator, whose contributions to the field of paleoanthropology were recognised with the National Geographic Society's LaGorce Medal and with an honorary doctorate of science degree from Case Western Reserve University. He found the Turkana boy skeleton Early life and education Kamoya Kimeu was born in 1938 in Makueni County, a rural area of southern Kenya, to Philomena Mwelu and Kimeu Mbalu. His father was a goat herder, but at the time of Kamoya's birth, was away working on a railroad construction project. Young Kamoya Kimeu attended a Christian missionary school for six years, but left once he was old enough to herd the family goats in the field. The native language of his family was Kikamba. He also learned to speak English and Swahili, which proved invaluable in later life, when he translated for visiting scientists with whom he worked. Career Kimeu began to work in paleoanthropology as a laborer fo ... [...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 genus, 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 synonym (taxonomy), synonymous with the contemporaneous and anatomically similar ''Homo habilis, 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 ...
