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. 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.
Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus Pongo, orangutans were originally considered to be one species. From 1996, they were divided into two species: the Bornean orangutan and the Sumatran orangutan. A third species, the Tapanuli orangutan, was identified definitively in 2017. The orangutans are the only surviving species of the subfamily Ponginae, which diverged genetically from the other hominids between 19.3 and 15.7 million years ago.
Australopithecus is a genus of early hominins that existed in Africa during the Late Pliocene and Early Pleistocene. The genera Homo, 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 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.
Java Man is an early human fossil discovered in 1891 and 1892 on the island of Java. Estimated to be between 700,000 and 2,000,000 years old, it was, at the time of its discovery, the oldest hominid fossils ever found, and it remains the type specimen for Homo erectus.
Mrs. Ples is the popular nickname for the most complete skull of an Australopithecus africanus ever found in South Africa. Many Australopithecus fossils have been found near Sterkfontein, about 40 kilometres (25 mi) northwest of Johannesburg, in a region of Gauteng now designated as the Cradle of Humankind World Heritage Site. Mrs. Ples was discovered by Robert Broom and John T. Robinson on April 18, 1947. Because of Broom's use of dynamite and pickaxe while excavating, Mrs. Ples's skull was blown into pieces and some fragments are missing. Nonetheless, Mrs./Mr. Ples is one of the most "perfect" pre-human skulls ever found. The skull is currently held at the Ditsong National Museum of Natural History in Pretoria.
Sivapithecus is a genus of extinct apes. Fossil remains of animals now assigned to this genus, dated from 12.2 million years old in the Miocene, have been found since the 19th century in the Siwalik Hills of the Indian subcontinent as well as in Kutch. Any one of the species in this genus may have been the ancestor to the modern orangutans.
Gigantopithecus is an extinct genus of ape from roughly 2 million to 350,000 years ago during the Early to Middle Pleistocene of southern China, represented by one species, Gigantopithecus blacki. Potential identifications have also been made in Thailand, Vietnam, and Indonesia. The first remains of Gigantopithecus, two third molar teeth, were identified in a drugstore by anthropologist Ralph von Koenigswald in 1935, who subsequently described the ape. In 1956, the first mandible and more than 1,000 teeth were found in Liucheng, and numerous more remains have since been found in at least 16 sites. Only teeth and four mandibles are known currently, and other skeletal elements were likely consumed by porcupines before they could fossilise. Gigantopithecus was once argued to be a hominin, a member of the human line, but it is now thought to be closely allied with orangutans, classified in the subfamily Ponginae.
Chantek, born at the Yerkes National Primate Research Center in Atlanta, Georgia, was a male hybrid Sumatran/Bornean orangutan who mastered the use of a number of intellectual skills, including American Sign Language (ASL), taught by American anthropologists Lyn Miles and Ann Southcombe. In Malay and Indonesian, cantik means "lovely" or "beautiful".
Birutė Marija Filomena Galdikas or Birutė Mary Galdikas, OC, is a Lithuanian-Canadian anthropologist, primatologist, conservationist, ethologist, and author. She is a professor at Simon Fraser University. In the field of primatology, Galdikas is recognized as a leading authority on orangutans. Prior to her field study of orangutans, scientists knew little about the species.
Chororapithecus is an extinct great ape from the Afar region of Ethiopia roughly 8 million years ago during the Late Miocene, comprising one species, C. abyssinicus. It is known from 9 isolated teeth discovered in a 2005–2007 survey of the Chorora Formation. The teeth are indistinguishable from those of gorillas in terms of absolute size and relative proportions, and it has been proposed to be an early member of Gorillini. However, this is controversial given the paucity of remains, and notable anatomical differences between Chororapithecus and gorilla teeth. The Kenyan ape Nakalipithecus has been proposed to be an ancestor of Chororapithecus or at least closely related. If correct, they would be the only identified fossil members of any modern non-human great ape lineage, and would push the gorilla–human last common ancestor from 8 million years ago to 10 million years ago. The teeth are adapted for processing tough plant fibres as well as hard, brittle food, and the formation is thought to represent a forested lakeside habitat.
The Boskop Man is an anatomically modern human fossil of the Middle Stone Age discovered in 1913 in South Africa. The fossil was at first described as Homo capensis and considered a separate human species by Broom (1918), but by the 1970s this "Boskopoid" type was widely recognized as representative of the modern Khoisan populations.
Sherwood Larned Washburn, nicknamed "Sherry", was an American physical anthropologist, and "a legend in the field." He was pioneer in the field of primatology, opening it to the study of primates in their natural habitats. His research and influence in the comparative analysis of primate behaviors to theories of human origins established a new course of study within the field of human evolution. He changed the field of anthropology with the publication of his paper The New Physical Anthropology, in 1951, in which he argued, convincingly, that human variation was continuous, and could not be broken up into discontinuous races.
Wushan Man is a set of fossilised remains of an extinct, undetermined non-hominin ape found in central China in 1985. The remains are dated to around 2 million years ago and were originally considered to represent a subspecies of Homo erectus.
Ian Tattersall is a British-born American paleoanthropologist and a curator emeritus with the American Museum of Natural History in New York City, New York. In addition to human evolution, Tattersall has worked extensively with lemurs. Tattersall is currently working with the Templeton Foundation.
Saldanha man also known as Saldanha cranium or Elandsfontein cranium are fossilized remains of an archaic human. It is one of the key specimens for Homo heidelbergensis. It has not been dated directly, and is estimated to be roughly 0.5 million years old. The remains, which included a fragment of lower jaw, were found on an exposed surface between shifting sand dunes on the farm Elandsfontein, which is located near Hopefield, South Africa.
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 ; Gorilla ; Pan ; and Homo, of which only modern humans remain.
Hispanopithecus is a genus of apes that inhabited Europe during the Miocene epoch. It was first identified in a 1944 paper by J. F. Villalta and M. Crusafont in Notas y Comunicaciones del Instituto Geologico y Minero de España. Anthropologists disagree as to whether Hispanopithecus belongs to the subfamily Ponginae or Homininae.
The Vietnamese orangutan is an extinct species of orangutan from the Pleistocene of Vietnam. It was named in honor of paleontologist Dirk Albert Hooijer. Fossils of the ape were found in the Tham Hai Cave. It is unclear whether Pongo hooijeri is truly a distinct species or merely a Vietnamese population of one of the extant orangutan species.
The phylogenetic split of Hominidae into the subfamilies Homininae and Ponginae is dated to the middle Miocene, roughly 18 to 14 million years ago. This split is also referenced as the "orangutan–human last common ancestor" by Jeffrey H. Schwartz, professor of anthropology at the University of Pittsburgh School of Arts and Sciences, and John Grehan, director of science at the Buffalo Museum.
Engis 2 refers to part of an assemblage, discovered in 1829 by Dutch physician and naturalist Philippe-Charles Schmerling in the lower of the Schmerling Caves. The pieces that make up Engis 2 are a partially preserved calvaria (cranium) and associated fragments of an upper and a lower jaw, a maxillary bone and an upper incisor tooth of a two to three year old Neanderthal child. The Schmerling Caves are situated just north of the Belgian municipality Engis, whence the name of this group. In 1833 Schmerling described and publicized the find, which included animal bones and stone tools. Recognizing their old age, he associated them with the "Ethiopian Type" of the diluvial period. Although it was not recognized as such until 1936, the publication represents the first scientific description of a Neanderthal fossil.
