History Of Luzon
The history of Luzon covers events that happened in the largest island of the Philippine Archipelago, Luzon. Luzon wrested the record of having the oldest man ever discovered in the Philippines with discovery of the Callao Man in 2007, which predated the Tabon Man by around 20,000 years.Morella, Cecil. (August 3, 2010)'Callao Man' Could Redraw Filipino History Agence France-Presse. Retrieved October 21, 2010 from Discovery News. The written history of Luzon began in around 900 AD with the discovery of the Laguna Copperplate Inscription in 1989. After that, Luzon began to appear in the annals of the Chinese and Japanese. One example would be the Ming Shilu, wherein Luzon appeared in 22 records. Luzon was split among Hindu-Buddhist kingdoms, Muslim principalities, and ethnoreligious tribes, who had trading connections with Borneo, Malaya, Java, Indochina, India, Okinawa, Japan and China before the Spanish established their rule. As a result of the Spanish–American War, Luzon becam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luzon
Luzon (; ) is the largest and most populous island in the Philippines. Located in the northern portion of the Philippines archipelago, it is the economic and political center of the nation, being home to the country's capital city, Manila, as well as Quezon City, the country's most populous city. With a population of 64 million , it contains 52.5% of the country's total population and is the fourth most populous island in the world. It is the 15th largest island in the world by land area. ''Luzon'' may also refer to one of the three primary island groups in the country. In this usage, it includes the Luzon mainland, the Batanes and Babuyan groups of islands to the north, Polillo Islands to the east, and the outlying islands of Catanduanes, Marinduque and Mindoro, among others, to the south. The islands of Masbate, Palawan and Romblon are also included, although these three are sometimes grouped with another of the island groups, the Visayas. Etymology The name ''Luz ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Floresiensis
''Homo floresiensis'' also known as "Flores Man"; nicknamed "Hobbit") is an extinct species of small archaic human that inhabited the island of Flores, Indonesia, until the arrival of modern humans about 50,000 years ago. The remains of an individual who would have stood about in height were discovered in 2003 at Liang Bua on the island of Flores in Indonesia. Partial skeletons of at least nine individuals have been recovered, including one complete skull, referred to as "LB1". These remains have been the subject of intense research to determine whether they were diseased modern humans or a separate species; a 2017 study concludes by phylogenetic analysis that ''H. floresiensis'' is an early species of ''Homo'', a sister species of ''Homo habilis''. This hominin was at first considered remarkable for its survival until relatively recent times, initially thought to be only 12,000 years ago. However, more extensive stratigraphic and chronological work has pushed the dating of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homo Sapiens
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically mod ...

Radiometric Dating
Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. The use of radiometric dating was first published in 1907 by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of Earth itself, and can also be used to date a wide range of natural and man-made materials. Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale. Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating. By al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metatarsal
The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes. Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and fifth metatarsal (often depicted with Roman numerals). The metatarsals are analogous to the metacarpal bones of the hand. The lengths of the metatarsal bones in humans are, in descending order, second, third, fourth, fifth, and first. Structure The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (proximally), and a head (distally).Platzer 2004, p. 220 The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above. The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Bradford Fox
Robert Bradford Fox (1918–1985) was an anthropologist and leading historian on pre-Hispanic Philippines. In 1958, Fox led a National Museum team in conducting extensive excavations on two sites at Calatagan, Batangas, in what may be considered the first systematic excavation involving the National Museum in the country. His report, published in 1959, was based on artifacts and information derived from 505 graves in two sites known as Kay Tomas and Pulong Bakaw. In the 1960s, by then the head of the Anthropology Division of the National Museum of the Philippines, he led a six-year archaeological research project in Palawan, focusing mainly on the caves and rockshelters of Lipuun Point in the southern part of the island. Its most outstanding site is the Tabon Cave complex, the large main cave delivered the only Pleistocene human fossils found in the Philippines to date. The fossil finds include a skullcap, jaw bones, teeth and several other fragmented bones. Dubbed the " Tabon M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callao Cave
Callao Cave () is one of 300 limestone caves located in the Barangays of Magdalo and Quibal in the municipality of Peñablanca, about northeast of Tuguegarao City, the capital of Cagayan province within the Peñablanca Protected Landscape and Seascape in the western foothills of the Northern Sierra Madre Mountains on Luzon island in the Philippines. The town Peñablanca's ( es, white rocks) name refers to the predominance of white limestone rock formations in the area. First excavated in 1980 by Maharlika Cuevas, the seven-chamber show cave is the best known natural tourist attraction of the Cagayan province and in February 2020 has officially been recognized as an ''important cultural property'' of the Philippines. Fossils of archaic humans, that lived during the Late Pleistocene were first discovered in the cave and documented in 2007 by a team led by Armand Salvador Mijares from the University of the Philippines and eventually confirmed in 2019 as to belong to a previously ...

Rizal, Kalinga
Rizal (formerly known as Liwan), officially the Municipality of Rizal is a 4th class municipality in the province of Kalinga, Philippines. According to the 2020 census, it has a population of 19,554 people. The town is famous for its Pleistocene sites which possesses rhino bones, tools, deer bones, turtle remains, and stegodon bones. The butchered rhino bones were confirmed by international scientific journals as proof of ancient hominids in the Philippines dating back to 709,000 years ago, the oldest hominid evidence in the entire Philippine archipelago. The discovery was confirmed in 2018, and has been a game-changer in Philippine prehistory. Geography Barangays Rizal is politically subdivided into 14 barangays. These barangays are headed by elected officials: Barangay Captain, Barangay Council, whose members are called Barangay Councilors. All are elected every three years. Climate Demographics In the 2020 census, the population of Rizal, Kalinga, was 19,554 people, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ph Locator Map Luzon
In chemistry, pH (), historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of ions) are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.Bates, Roger G. ''Determination of pH: theory and practice''. Wiley, 1973. :\ce = - \log(a_\ce) = -\log( ce\ce M) where M = mol dm−3. At 25 °C (77 °F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (i.e. have the same concentration of H+ ions as OH− ions, i.e. pure water). The neutral value of the pH depends on the temperaturebeing lower than 7 if the temperature increases above 25 °C. The pH value can be less than 0 for very concentrated strong ac ...
