Java Man
Java Man (''Homo erectus erectus'', formerly also ''Anthropopithecus erectus'', ''Pithecanthropus erectus'') is an early human fossil discovered in 1891 and 1892 on the island of Java (Dutch East Indies, now part of Indonesia). 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''. Led by Eugène Dubois, the excavation team uncovered a tooth, a skullcap, and a thighbone at Trinil on the banks of the Solo River in East Java. Arguing that the fossils represented the " missing link" between apes and humans, Dubois gave the species the scientific name ''Anthropopithecus erectus'', then later renamed it ''Pithecanthropus erectus''. The fossil aroused much controversy. Less than ten years after 1891, almost eighty books or articles had been published on Dubois's finds. Despite Dubois's argument, few accepted that Java Man was a transitional form betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntype
In biological nomenclature, a syntype is any one of two or more biological types that is listed in a description of a taxon where no holotype was designated. Precise definitions of this and related terms for types have been established as part of the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants. In zoology In zoological nomenclature, a syntype is defined as "Each specimen of a type series (q.v.) from which neither a holotype nor a lectotype has been designated rts. 72.1.2, 73.2, 74 The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code ). Historically, syntypes were often explicitly designated as such, and under the present ICZN this is a requirement (Art. 72.3), but modern attempts to publish species or subspecies descriptions based on syntypes are generally frowned upon by practicing taxonomists, and most are gradually being replaced by lectotypes. Those that still ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transitional Fossil
A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. This is especially important where the descendant group is sharply differentiated by gross anatomy and mode of living from the ancestral group. These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation. Because of the incompleteness of the fossil record, there is usually no way to know exactly how close a transitional fossil is to the point of divergence. Therefore, it cannot be assumed that transitional fossils are direct ancestors of more recent groups, though they are frequently used as models for such ancestors. In 1859, when Charles Darwin's ''On the Origin of Species'' was first published, the fossil record was poorly known. Darwin described the perceived lack of transitional fossils as "the most obvious and gravest objection which can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rijksmuseum Van Geologie En Mineralogie
The Rijksmuseum van Geologie en Mineralogie was a museum of geological and mineralogical collections. Up to 1878, geological and mineralogical collections formed part of Rijksmuseum van Natuurlijke Historie, the National Museum of Natural History. This museum, founded in 1820 and established at Leiden, was closely linked with the university there. One of the staff members used to be in charge of the geological collections. In 1893 the collection was moved into a new building at the Van der Werffpark/Garenmarkt as the Rijksmuseum van Geologie en Mineralogie, representing a great step forward. The RGM thus became completely independent and was no longer regarded as part of the Natural History Museum. History A list of the early curators of the museum and their roles in the museum's history are included here. K. Martin (1878-1922) Proposed by the then director of the Natural History Museum, H.

Sangiran
Sangiran is an archaeological excavation site in Java in Indonesia. According to a UNESCO report (1995) "Sangiran is recognized by scientists to be one of the most important sites in the world for studying fossil man, ranking alongside Zhoukoudian (China), Willandra Lakes (Australia), Olduvai Gorge (Tanzania), and Sterkfontein (South Africa), and more fruitful in finds than any of these." The area comprises about 56 km² (7 km x 8 km). It is located in Central Java, about 15 kilometers north of Surakarta in the Solo River valley. Administratively, Sangiran area is divided between 2 regencies: Sragen (districts of Gemolong, Kalijambe, and Plupuh) and Karanganyar (district of Gondangrejo). An important feature of the site is the geology of the area. Originally a dome was created millions of years ago through tectonic uplifts. The dome was then eroded exposing beds within the dome which are rich in archeological records. History * 1883: The Dutch paleoanth ...

Early Hominids In Southeast Asia
:''See Peopling of Southeast Asia for anatomically modern humans.'' The region of Southeast Asia is considered a possible place for the evidence of archaic human remains that could be found due to the pathway between Australia and mainland Southeast Asia, where the migration of multiple early humans has occurred out of Africa. One of many pieces of evidence is of the early human found in central Java of Indonesia in the late 1800s by Eugene Dubois, and later in 1937 at Sangiran site by G.H.R. van Koenigswald. These skull and fossil materials are ''Homo erectus'', named ''Pithecanthropus erectus'' by Dubois and '' Meganthropus palaeojavanicus'' by van Koenigswald. They were dated to c. 1.88 and 1.66 Ma, as suggested by Swisher ''et al''. by analysis of volcanic rocks. Three possible migration routes through Southeast Asia Most scholars who work in Southeast Asia attempt to establish the possible route through which early humans would migrate passing through the region after they ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...

Peking Man
Peking Man (''Homo erectus pekinensis'') is a subspecies of ''Homo erectus, H. erectus'' which inhabited the Zhoukoudian Cave of northern China during the Middle Pleistocene. The first fossil, a tooth, was discovered in 1921, and the Zhoukoudian Cave has since then become the most productive ''H. erectus'' site in the world. Peking Man was instrumental in the foundation of Chinese anthropology, and fostered an important dialogue between Western and Eastern science for decades to come. The fossils became the centre of anthropological discussion, and were classified as a direct human ancestor, propping up the Out of Asia hypothesis that humans evolved in Asia. Peking Man also played a vital role in the restructuring of the Chinese identity following the Chinese Communist Revolution, and was intensively communicated to working class and peasant communities to introduce them to Marxism and science (overturning deeply-rooted superstitions and Chinese creation myths, creation myths). ...

Gibbon
Gibbons () are apes in the family Hylobatidae (). The family historically contained one genus, but now is split into four extant genera and 20 species. Gibbons live in subtropical and tropical rainforest from eastern Bangladesh to Northeast India to southern China and Indonesia (including the islands of Sumatra, Borneo and Java). Also called the lesser apes, gibbons differ from great apes ( bonobos, chimpanzees, gorillas, orangutans and humans) in being smaller, exhibiting low sexual dimorphism, and not making nests. Like all apes, gibbons are tailless. Unlike most of the great apes, gibbons frequently form long-term pair bonds. Their primary mode of locomotion, brachiation, involves swinging from branch to branch for distances up to , at speeds as fast as . They can also make leaps up to , and walk bipedally with their arms raised for balance. They are the fastest of all tree-dwelling, nonflying mammals. Depending on the species and sex, gibbons' fur coloration varies from dar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
