Ralph Works Chaney
Ralph Works Chaney (August 24, 1890 – March 3, 1971) was an American paleobotanist. Early life Chaney was born on August 24, 1890 in Brainerd, Illinois. He attended Hyde Park Academy High School, and began to cultivate his interest in ornithology. He became an avid bird watcher and collected a series of bird eggs and skins. After his graduation, Chaney briefly moved to South Dakota before enrolling at the University of Chicago in the fall of 1908. It was here where his interests shifted from ornithology to botany, and eventually paleobotany. He earned his B.S. degree in geology from the University of Chicago in 1912. Career Chaney began to work towards a graduate degree in paleontology at the University of Chicago, studying under Stuart Weller. After two years, he found that he did not especially enjoy his Paleozoic studies. In the summer of 1913, he was hired as a cook by the U.S. Geological Survey and spent the summer months in the Matanuska Valley of Alaska. He was part ...

Washington Heights, Chicago
Washington Heights is the 73rd of Chicago's 77 community areas. Located from the Loop, it is on the city's far south side. Washington Heights is considered part of the Blue Island Ridge, along with the nearby community areas of Beverly, Morgan Park and Mount Greenwood, and the village of Blue Island. It contains a neighborhood also known as Washington Heights, as well as the neighborhoods of Brainerd and Fernwood. , Washington Heights had 27,453 inhabitants. Named for the heights which are now part of the adjacent Beverly, the area was settled in the late 19th century at the intersection of two railroad lines. It was incorporated as a village in 1874, and was annexed by Chicago in 1890. During most of the 20th century, Washington Heights was primarily inhabited by Irish, Germans and Swedes; after late-20th-century white flight, it has been mainly inhabited by African-Americans. The area largely retained its middle-class character during its racial transition, decli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.

Civil Defence Corps
The Civil Defence Corps (CDC) was a civilian volunteer organisation established in Great Britain in 1949 to mobilise and take local control of the affected area in the aftermath of a major national emergency, principally envisaged as being a Cold War nuclear attack. By March 1956, the Civil Defence Corps had 330,000 personnel."A Brief History of Civil Defence", Tim Essex-Lopresto, Civil Defence Association, , 2005 It was stood down in Great Britain in 1968, although two Civil Defence Corps still operate within the British Isles, namely the Isle of Man Civil Defence Corps and the unrelated Civil Defence Ireland in the Republic of Ireland. Many other countries maintain a national Civil Defence Corps, usually having a wide brief for assisting in large scale civil emergencies such as flood, earthquake, invasion, or civil disorder. The unit has now been re-established. The Joint Civil Aid Corps – a voluntary Civil Defence (Emergency Support) organisation. Its concept is to provide ...

World War II
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] |
Paleontological Society Of America
The Paleontological Society, formerly the Paleontological Society of America, is an international organisation devoted to the promotion of paleontology. The Society was founded in 1908 in Baltimore, Maryland, and was incorporated in April 1968 in the District of Columbia. The Society publishes the bi-monthly ''Journal of Paleontology'' and the quarterly ''Paleobiology'', holds an annual meeting in the autumn in conjunction with the Geological Society of America, sponsors conferences and lectures, and provides grants and scholarships. The Society has five geographic sections—Pacific Coast (founded March 1911), North-Central (founded May 1974), Northeastern (founded March 1977), Southeastern (founded November 1979), Rocky Mountain (founded October 1985), and South-Central (founded November 1988).

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Davidson Black
Davidson Black, FRS (July 25, 1884 – March 15, 1934) was a Canadian paleoanthropologist, best known for his naming of ''Sinanthropus pekinensis'' (now ''Homo erectus pekinensis''). He was Chairman of the Geological Survey of China and a Fellow of the Royal Society. He was known as 步達生 (pinyin: Bù Dáshēng) in China. Early years Black was born in 1884, in Toronto, Ontario, Canada. When he was a child, he would spend many summers near or on the Kawartha lakes. As a teenager, he would carry heavy loads of supplies for the Hudson's Bay Company. He also enjoyed collecting fossils along the banks of the Don River. He also became friends with First Nations people, and learned one First Nations language. Black also searched unsuccessfully for gold along the Kawartha lakes. Black showed an interest in biology at an early age, despite being born to a family association with law. In 1906, Black gained a degree in medical science from the University of Toronto. He continu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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). ...
