Tabon Man
Tabon Man refers to remains discovered in the Tabon Caves in Lipuun Point in Quezon, Palawan in the Philippines. They were discovered by Robert B. Fox, an American anthropologist of the National Museum of the Philippines, on May 28, 1962. These remains, the fossilized fragments of a skull of a female and the jawbones of three individuals dating back to 16,500 years ago, were the earliest known human remains in the Philippines, until a metatarsal from the Callao Man discovered in 2007 was dated in 2010 by uranium-series dating as being 67,000 years old. However, some scientists think additional evidence is necessary to confirm those fossils as a new species, rather than a locally adapted population of other ''Homo'' populations, such as ''H. erectus'' or Denisovan. The Tabon fragments are named after the Tabon Caves, where they were found on the west coast of Palawan. The cave complex appears to have been a kind of Stone Age factory, with both finished stone flake t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tabon Caves
The Tabon Caves, dubbed as the ''Philippines' Cradle of Civilization'', are a group of caves located on Lipuun Point, north of Quezon municipality, in the south western part of the province of Palawan on Palawan Island, in the Philippines. They are part of the Lipuun Point Reservation, which has been protected by the government of the Philippines as a museum reservation to protect the caves and immediate vicinity from deforestation and to preserve the cultural artifacts present there. The caves are named after the Tabon scrubfowl. It is bordered on the south by the town proper of Quezon, Panitian on the west, and the South China Sea on the north and east. Out of 215 known caves, 29 have been explored and seven of these are open to the public. The seven include Tabon, Diwata, Igang and Liyang Caves. One of the oldest human bones found in the Philippines, the Tabon Man, was found here in 1962. Other excavated, unexamined remains are stored onsite. In 2006, the ''Tabon Cave Comp ...

Calvaria (skull)
The calvaria is the top part of the skull. It is the upper part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. In the human skull, the sutures between the bones normally remain flexible during the first few years of postnatal development, and fontanelles are palpable. Premature complete ossification of these sutures is called craniosynostosis. In Latin, the word ''calvaria'' is used as a feminine noun with plural ''calvariae''; however, many medical texts list the word as ''calvarium'', a neuter Latin noun with plural ''calvaria''. Structure The outer surface of the skull possesses a number of landmarks. The point at which the frontal bone and the two parietal bones meet is known as "Bregma". The point at which the two parietal bones and the occipital bone meet is known as "Lambda". Not only do t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Negrito
The term Negrito () refers to several diverse ethnic groups who inhabit isolated parts of Southeast Asia and the Andaman Islands. Populations often described as Negrito include: the Andamanese peoples (including the Great Andamanese, the Onge, the Jarawa, and the Sentinelese) of the Andaman Islands, the Semang peoples (among them, the Batek people) of Peninsular Malaysia, the Maniq people of Southern Thailand, as well as the Aeta of Luzon Island, Ati, and Tumandok of Panay Island, Agta of Sierra Madre and Mamanwa of Mindanao Island and about 30 other officially recognized ethnic groups in the Philippines. Etymology The word ''Negrito'' is the Spanish diminutive of ''negro'', used to mean "little black person." This usage was coined by 16th-century Spanish missionaries operating in the Philippines, and was borrowed by other European travellers and colonialists across Austronesia to label various peoples perceived as sharing relatively small physical stature and dark skin.

Aboriginal Tasmanians
The Aboriginal Tasmanians (Palawa kani: ''Palawa'' or ''Pakana'') are the Aboriginal people of the Australian island of Tasmania, located south of the mainland. For much of the 20th century, the Tasmanian Aboriginal people were widely, and erroneously, thought of as being an extinct cultural and ethnic group that had been intentionally exterminated by white settlers. Contemporary figures (2016) for the number of people of Tasmanian Aboriginal descent vary according to the criteria used to determine this identity, ranging from 6,000 to over 23,000. First arriving in Tasmania (then a peninsula of Australia) around 40,000 years ago, the ancestors of the Aboriginal Tasmanians were cut off from the Australian mainland by rising sea levels c. 6000 BC. They were entirely isolated from the outside world for 8,000 years until European contact. Before British colonisation of Tasmania in 1803, there were an estimated 3,000–15,000 Palawa. The Palawa population suffered a drastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ainu People
The Ainu are the indigenous people of the lands surrounding the Sea of Okhotsk, including Hokkaido Island, Northeast Honshu Island, Sakhalin Island, the Kuril Islands, the Kamchatka Peninsula and Khabarovsk Krai, before the arrival of the Yamato Japanese and Russians. These regions are referred to as in historical Japanese texts. Official estimates place the total Ainu population of Japan at 25,000. Unofficial estimates place the total population at 200,000 or higher, as the near-total assimilation of the Ainu into Japanese society has resulted in many individuals of Ainu descent having no knowledge of their ancestry. As of 2000, the number of "pure" Ainu was estimated at about 300 people. In 1966, there were about 300 native Ainu speakers; in 2008, however, there were about 100. Names This people's most widely known ethnonym, "Ainu" ( ain, ; ja, アイヌ; russian: Айны) means "human" in the Ainu language, particularly as opposed to , divine beings. Ainu also i ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongoloid
Mongoloid () is an obsolete racial grouping of various peoples indigenous to large parts of Asia, the Americas, and some regions in Europe and Oceania. The term is derived from a now-disproven theory of biological race. In the past, other terms such as " Mongolian race", "yellow", "Asiatic" and "Oriental" have been used as synonyms. The concept of dividing humankind into the Mongoloid, Caucasoid, and Negroid races was introduced in the 1780s by members of the Göttingen School of History. It was further developed by Western scholars in the context of racist ideologies during the age of colonialism. The organization has since been renamed the American Association of Biological Anthropologists. With the rise of modern genetics, the concept of distinct human races in a biological sense has become obsolete. In 2019, the American Association of Biological Anthropologists stated: "The belief in 'races' as natural aspects of human biology, and the structures of inequality (racism) that ...

Homo Erectus
''Homo erectus'' (; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Several human species, such as '' H. heidelbergensis'' and '' H. antecessor'' — with the former generally considered to have been the ancestor to Neanderthals, Denisovans, and modern humans — appear to have evolved from ''H. erectus''. Its specimens are among the first recognizable members of the genus ''Homo''. ''H. erectus'' was the first human ancestor to spread throughout Eurasia, with a continental range extending from the Iberian Peninsula to Java. Asian populations of ''H. erectus'' may be ancestral to '' H. floresiensis'' and possibly to '' H. luzonensis''. The last known population of ''H. erectus'' is '' H. e. soloensis'' from Java, around 117,000–108,000 years ago. ''H. erectus'' had a more modern gait and body proportions, and was the first human species to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...

Guano
Guano (Spanish from qu, wanu) is the accumulated excrement of seabirds or bats. As a manure, guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern input-intensive farming. The demand for guano spurred the human colonization of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano. U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
