Nyanzapithecus
''Nyanzapithecus'' is an extinct genus of primate from the Middle Miocene of Maboko Island, Nyanza Province, Kenya. This genus is known from four species. It had an average body mass of around . Taxonomy Fifteen cranio-dental specimens of this species were collected from the island between the years 1933-73. During an expedition to Maboko Island in 1982–83, paleoanthropologist Martin Pickford recovered more than a hundred small catarrhine fossils. Among them, described the new genus and species ''Nyanzapithecus pickfordi'', characterized by several dental specializations, and also transferred the '' Rangwapithecus'' species ''R. vancouveringi'' to the genus renaming it ''N. vancouveringorum''. ''Nyanzapithecus'' was considered closely related to ''Rangwapithecus'' and '' Mabokopithecus'' based on dental similarities, and an early relative of ''Oreopithecus bambolii''. ''Nyanzapithecus'' was originally included in Oreopithecidae before being transferred to Proconsulidae. de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maboko Island
Maboko Island is a small island lying in the Winam Gulf of Lake Victoria, in Nyanza Province of western Kenya. It is about 1.8 km long by 1 km wide. It is an important Middle Miocene, Middle Miocene Paleontology, paleontological site with fossiliferous deposits that were discovered in the 1930s. The age of the deposits is estimated to be , and they are especially important for the abundance of primate fossils they contain. Excavations Miocene fossils in the fluvial deposits of Maboko was first discovered by Walter Edwin Owen, Archdeacon W.E. Owen in 1933, who started an excavation later that year which yielded a lot of vertebrate fossils. Owen's excavations continued the following two years supervised by Donald Gordon MacInnes. Then few expeditions visited the island before MacInnes returned together with Louis Leakey in 1947. These excavations resulted in a large number of craniodental (crania and teeth) remains of a medium seized cercopithecoid monkey and cranial and postcr ...

Oreopithecus
''Oreopithecus'' (from the Greek , and , , meaning "hill-ape") is an extinct genus of ape from the Miocene epoch whose fossils have been found in today's Tuscany and Sardinia in Italy. It existed 9–7 million years ago in the Tusco-Sardinian area when this region was an isolated island in a chain of islands stretching from central Europe to northern Africa in what was becoming the Mediterranean Sea. ''Oreopithecus'' was one of many European immigrants that settled this area in the Vallesian–Turolian transition and one of few hominoids, together with '' Sivapithecus'' in Asia, to survive the so-called Vallesian Crisis. To date, dozens of individuals have been discovered at the Tuscan localities of Montebamboli, Montemassi, Casteani, Ribolla, and, most notably, in the fossil-rich lignite mine in the Baccinello Basin, making it one of the best-represented fossil apes. Evolutionary history ''Oreopithecus bambolii'' was first described by French paleontologist Paul Gervais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nyanza Province
Nyanza Province (; ) was one of Kenya's eight administrative provinces before the formation of the 47 counties under the 2010 constitution. Six counties were organised in the area of the former province. The region is located in the southwestern part of Kenya around Lake Victoria. It includes part of the eastern edge of the lake and is inhabited predominantly by the Luo people and Kisii people. There are also Bantu-speaking tribes, such as the Kuria, and some Luhya, living in the province. The province derives its name from ''Nyanza,'' a Bantu word which means a large mass of water. The provincial capital was Kisumu, the third-largest city in Kenya. The province had a population of 4,392,196 at the 1999 census within an area of 16.162 km2, or 12.613 km2 of land. The climate is tropical humid. Counties The following counties make up the area of the former Nyanza province: Districts after 2007 Several new districts were created in 2007 in Kenya, some ...

Kenya
Kenya, officially the Republic of Kenya, is a country located in East Africa. With an estimated population of more than 52.4 million as of mid-2024, Kenya is the 27th-most-populous country in the world and the 7th most populous in Africa. Kenya's capital and largest city is Nairobi. Its second-largest and oldest city is Mombasa, a major port city located on Mombasa Island. Other major cities within the country include Kisumu, Nakuru & Eldoret. Going clockwise, Kenya is bordered by South Sudan to the northwest (though much of that border includes the disputed Ilemi Triangle), Ethiopia to the north, Somalia to the east, the Indian Ocean to the southeast, Tanzania to the southwest, and Lake Victoria and Uganda to the west. Kenya's geography, climate and population vary widely. In western, rift valley counties, the landscape includes cold, snow-capped mountaintops (such as Batian, Nelion and Point Lenana on Mount Kenya) with vast surrounding forests, wildlife and ...

Catarrhine
The parvorder Catarrhini (known commonly as catarrhine monkeys, Old World anthropoids, or Old World monkeys) consists of the Cercopithecoidea and apes (Hominoidea). In 1812, Geoffroy grouped those two groups together and established the name Catarrhini, "Old World monkeys", ("''singes de l'Ancien Monde''" in French). Its sister in the infraorder Simiiformes is the parvorder Platyrrhini (New World monkeys). There has been some resistance to directly designate apes (and thus humans) as monkeys despite the scientific evidence, so "Old World monkey" may be taken to mean the Cercopithecoidea or the Catarrhini. That apes are monkeys was already realized by Georges-Louis Leclerc, Comte de Buffon in the 18th century. Linnaeus placed this group in 1758 together with what we now recognise as the tarsiers and the New World monkeys, in a single genus "''Simia''" (sans ''Homo''). The Catarrhini are all native to Africa and Asia. Members of this parvorder are called catarrhines. The Catarrh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rangwapithecus
''Rangwapithecus'' is an extinct genus of ape from the Early Miocene of Kenya. Late Miocene phalanges from Hungary have also been assigned to this genus, but were later reclassified as ''Dryopithecus''. Description ''Rangwapithecus'' weighed approximately and the size and shape of the ape's teeth indicate that it was a folivore. An arboreal ape from the earliest Miocene adapted to life in the rainforest, it is associated particularly with Mfangano Island although the species previously inhabited a woodland-bushland environment. Taxonomy ''Rangwapithecus'' was sympatric with ''Proconsul'', and may be synonymous with both ''Proconsul gordoni'' and ''Proconsul vancouveringi''. It is also similar to another species found in Africa. ''Rangwapithecus gordoni'' and ''P. africanus'' are similarly sized though they differ morphologically, and both are restricted to Koru and Songhur. Palaeoecology ''Rangwapithecus'' was a generalised frugivore that was also able to engage in folivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecificity
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
