Selam (Australopithecus)
Selam (DIK-1/1) is the fossilized skull and other skeletal remains of a three-year-old ''Australopithecus afarensis'' female hominin, whose bones were first found in Dikika, in the Afar Region of northeastern Ethiopia in 2000 and recovered over the following years. Although she has often been nicknamed Lucy's baby, the specimen has been dated at 3.3 million years ago, approximately 100,000 years older than "Lucy (Australopithecus), Lucy" (dated to about 3.2 million years ago). Selam is also known as the Dikika Child. The word "Selam" means "peace" in Amharic. Discovery The fossils were discovered by Zeresenay Alemseged, and are remarkable for their age and condition. On 20 September 2006, the journal ''Nature'' presented the findings of a dig in Dikika, Ethiopia, a few miles south of Hadar, Ethiopia, Hadar, the well-known site where the fossil hominin known as Lucy was found. The recovered skeleton comprises almost the entire skull and torso and many parts of the limbs. The feat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australopithecus Afarensis
''Australopithecus afarensis'' is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. From 1972 to 1977, the International Afar Research Expedition—led by anthropologists Maurice Taieb, Donald Johanson and Yves Coppens—unearthed several hundreds of hominin specimens in Hadar, Ethiopia, Hadar, Ethiopia, the most significant being the exceedingly well-preserved skeleton AL 288-1 ("Lucy (Australopithecus), Lucy") and the site AL 333 ("the First Family"). Beginning in 1974, Mary Leakey led an expedition into Laetoli, Tanzania, and notably recovered fossil trackways. In 1978, the species was first species description, described, but this was followed by arguments for splitting the wealth of specimens into different species given the wide range of variation which had been attributed to sexual dimorphi ...

Hominid
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'' (the Bornean, Sumatran and Tapanuli orangutan); '' Gorilla'' (the eastern and western gorilla); '' Pan'' (the chimpanzee and the bonobo); and ''Homo'', of which only modern humans (''Homo sapiens'') remain. Numerous revisions in classifying the great apes have caused the use of the term ''hominid'' to change over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans and other apes were considered to be "hominids". The earlier restrictive meaning has now been largely assumed by the term ''hominin'', which comprises all members of the human clade after the split from the chimpanzees (''Pan''). The current meaning of "hominid" includes all the great apes including humans. Usage still varies, however, and some scientis ...

Neogene Fossil Record
The Neogene ( ,) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period million years ago. It is the second period of the Cenozoic and the eleventh period of the Phanerozoic. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). The earlier term Tertiary Period was used to define the span of time now covered by Paleogene and Neogene and, despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use. During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''H ...

Australopithecus Fossils
''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 '' 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. Furthermore, because e.g. ''A. africanus'' is more closely related to humans, or their ancestors at the time, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taung Child
The Taung Child (or Taung Baby) is the fossilised skull of a young ''Australopithecus africanus''. It was discovered in 1924 by quarrymen working for the Northern Lime Company in Taung, South Africa. Raymond Dart described it as a new species in the journal ''Nature'' in 1925. The Taung skull is in repository at the University of Witwatersrand. Dean Falk, a specialist in brain evolution, has called it "the most important anthropological fossil of the twentieth century." Description The Taung Child was originally thought to have been about six years old at death because of the presence of deciduous teeth, but is now believed to have been about three or four, based on studies of rates of enamel deposition on the teeth. There was some debate over the age of the child, initially because it was unclear if they grew at the speed of a human, or of an ape. Compared to an ape, they would have been aged about 4 years, and compared to a human, they would have been aged around 5–7 y ...

List Of Human Evolution Fossils
The following tables give an overview of notable finds of Hominini, hominin fossils and Skeleton, remains relating to human evolution, beginning with the formation of the tribe Hominini (the divergence of the Chimpanzee–human last common ancestor, human and chimpanzee lineages) in the late Miocene, roughly 7 to 8 million years ago. As there are thousands of fossils, mostly fragmentary, often consisting of single bones or isolated teeth with complete skulls and skeletons rare, this overview is not complete, but shows some of the most important findings. The fossils are arranged by approximate age as determined by radiometric dating and/or incremental dating and the species name represents current consensus; if there is no clear scientific consensus the other possible classifications are indicated. The early fossils shown are not considered ancestors to ''Homo sapiens'' but are closely related to ancestors and are therefore important to the study of the lineage. After 1.5 million ...

Human Timeline
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, ''Homo sapiens'', throughout the history of life, beginning some 4 billion years ago down to recent evolution within ''H. sapiens'' during and since the Last Glacial Period. It includes brief explanations of the various taxonomic ranks in the human lineage. The timeline reflects the mainstream views in modern taxonomy, based on the principle of phylogenetic nomenclature; in cases of open questions with no clear consensus, the main competing possibilities are briefly outlined.

Homininae
Homininae (the hominines) is a subfamily of the family Hominidae (hominids). (The Homininae——encompass humans, and are also called "African hominids" or "African apes".) This subfamily includes two tribes, Hominini and Gorillini, both having extant (or living) species as well as extinct species. Tribe Hominini includes: the extant genus ''Homo'', which comprises only one extant species—the modern humans (''Homo'' sapiens), and numerous extinct human species; and the extant genus '' Pan'', which includes two extant species, chimpanzees and bonobos. Tribe Gorillini (gorillas) contains one extant genus, Gorilla, with two extant species, with variants, and one known extinct genus. Alternatively, the genus ''Pan'' is considered by some to belong, instead of to a subtribe Panina, to its own separate tribe, (''so-called'') "Panini"—which would be a third tribe for Homininae. Some classification schemes provide a more comprehensive account of extinct groups—(see section "Taxo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australopithecus Africanus
''Australopithecus africanus'' is an extinct species of australopithecine which lived between about 3.3 and 2.1 million years ago in the Late Pliocene to Early Pleistocene of South Africa. The species has been recovered from Taung, Sterkfontein, Makapansgat, and Gladysvale. The first specimen, the Taung child, was described by anatomist Raymond Dart in 1924, and was the first early hominin found. However, its closer relations to humans than to other apes would not become widely accepted until the middle of the century because most had believed humans evolved outside of Africa. It is unclear how ''A. africanus'' relates to other hominins, being variously placed as ancestral to ''Homo'' and ''Paranthropus'', to just ''Paranthropus'', or to just '' P. robustus''. The specimen " Little Foot" is the most completely preserved early hominin, with 90% of the skeleton intact, and the oldest South African australopith. However, it is controversially suggested that it and similar speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Geographic Magazine
''National Geographic'' (formerly ''The National Geographic Magazine'', sometimes branded as ''Nat Geo'') is an American monthly magazine published by National Geographic Partners. The magazine was founded in 1888 as a scholarly journal, nine months after the establishment of the society, but is now a popular magazine. In 1905, it began including pictures, a style for which it became well known. Its first color photos appeared in the 1910s. During the Cold War, the magazine committed itself to present a balanced view of the physical and human geography of countries beyond the Iron Curtain. Later, the magazine became outspoken on environmental issues. Until 2015, the magazine was completely owned and managed by the National Geographic Society. Since 2015, controlling interest has been held by National Geographic Partners. Topics of features generally concern geography, history, nature, science, and world culture. The magazine is well known for its distinctive appearance: a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
