Rama's Setu
Adam's Bridge, '; ta, ஆதாம் பாலம் ' also known as Rama's Bridge or ''Rama Setu'', '; ta, ராமர் பாலம் '; sa, रामसेतु ' is a chain of natural limestone shoals, between Pamban Island, also known as Rameswaram Island, off the south-eastern coast of Tamil Nadu, India, and Mannar Island, off the north-western coast of Sri Lanka. Geological evidence suggests that this bridge is a former land connection between India and Sri Lanka. The feature is long and separates the Gulf of Mannar (southwest) from the Palk Strait (northeast). Some of the regions are dry, and the sea in the area rarely exceeds in depth, thus hindering navigation. It was reportedly passable on foot until the 15th century when storms deepened the channel. Ramanathaswamy Temple records say that Adam's Bridge was entirely above sea level until it broke in a cyclone in 1480. Etymology The western world came to know of the bridge via Ibn Khordadbeh's '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Garden Of Eden
In Abrahamic religions, the Garden of Eden ( he, גַּן־עֵדֶן, ) or Garden of God (, and גַן־אֱלֹהִים ''gan-Elohim''), also called the Terrestrial Paradise, is the Bible, biblical paradise described in Book of Genesis, Genesis 2-3 and Book of Ezekiel, Ezekiel 28 and 31. The location of Eden is described in the Book of Genesis as the source of four tributaries. Various suggestions have been made for its location: at the head of the Persian Gulf, in southern Mesopotamia (now Iraq) where the Tigris and Euphrates rivers run into the sea; and in Armenia. Like the Genesis flood narrative, the Genesis creation narrative and the account of the Tower of Babel, the story of Eden echoes the Ancient Mesopotamian religion, Mesopotamian myth of a king, as a primordial man, who is placed in a divine garden to guard the tree of life. The Hebrew Bible depicts Adam and Eve as walking around the Garden of Eden naked due to their sinlessness. Mentions of Eden are also made in ...

Journal Of Biogeography
The ''Journal of Biogeography'' is a peer-reviewed scientific journal in biogeography that was established in 1974. It covers aspects of spatial, ecological, and historical biogeography. The founding editor-in-chief was David Watts, followed by John Flenley, Philip Stott (1987-2004), Robert J. Whittaker (2004-2015), and Peter Linder (University of Zurich; 2015-2019). The current editor-in-chief is Michael N Dawson (University of California, Merced).

Allopatric Speciation
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sidney Dillon Ripley
Sidney Dillon Ripley II (September 20, 1913 – March 12, 2001) was an American ornithologist and wildlife conservationist. He served as secretary of the Smithsonian Institution for 20 years, from 1964 to 1984, leading the institution through its period of greatest growth and expansion. For his leadership at the Smithsonian, he was awarded the Presidential Medal of Freedom by Ronald Reagan in 1985. Biography Early life Ripley was born in New York City, after a brother, Louis, was born in 1906 in Litchfield, Connecticut. His mother was Constance Baillie Rose of Scottish descent while his father was Louis Arthur Dillon Ripley, a wealthy real estate agent who drove around in an 1898 Renault Voiturette. Both his paternal grandparents, Julia and Josiah Dwight Ripley, died before he was born but he connected to them was through Cora Dillon Wyckoff. Great Aunt Cora and her husband, Dr. Peter Wyckoff, often hosted young Ripley at their Park Avenue apartment. Cora's and Julia's f ...

Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Space Research Organisation
The Indian Space Research Organisation (ISRO; ) is the national space agency of India, headquartered in Bengaluru. It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO acts as the executive of DOS as well. ISRO is India's primary agency for performing tasks related to space-based applications, space exploration and the development of related technologies. It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites. The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru under the Department of Atomic Energy (DAE) in 1962, on the urging of scientist Vikram Sarabhai, recognising the need in space research. INCOSPAR grew and became ISRO in 1969, within DAE. In 1972, the government of India set up a Space Commissi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pamban Bridge
Pamban Bridge is a railway bridge that connects the town of Mandapam in mainland India with Rameswaram on Pamban Island. Opened on 24 February 1914, it was India's first sea bridge, and was the longest sea bridge in India until the opening of the Bandra-Worli Sea Link in 2010. The rail bridge is, for the most part, a conventional bridge resting on concrete piers but has a double-leaf Bascule bridge, bascule section midway, which can be raised to let ships and barges pass through. Until 1988, the Pamban bridge was the only surface transport that connected Tamil Nadu's island of Rameswaram to the mainland. In December 2018, the bascule of this bridge was damaged, which suspended transportation on the bridge for 3 months. Rail movement was again restored on 27 February 2019. In 1988, a road bridge was also constructed parallel to the rail bridge. This road bridge is also known as Annai Indira Gandhi Road Bridge. The Annai Indira Gandhi Road Bridge connects the National Highway (NH ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dhanushkodi
Dhanushkodi is an abandoned town at the south-eastern tip of Pamban Island of the state of Tamil Nadu in India. It is south-east of Pamban and is about west of Talaimannar in Sri Lanka. The town was destroyed during the 1964 Rameswaram cyclone and remains uninhabited in the aftermath. Today only a few vendors and restaurants can be seen at Dhanushkodi during the day along with the ruins of the long destroyed town. Geography Dhanushkodi is on the tip of Pamban island, separated from the mainland by the Palk Strait. Transport The National Highway completed the 9.5-km-long road – 5 km from Mukuntharayar Chathiram to Dhanushkodi and 4.5 km from Dhanushkodi to Arichamunai. Until 2016, Dhanushkodi was reachable either on foot along the seashore or in jeeps. In 2016, a road was completed from the village of Mukundarayar Chathiram. A metre gauge railway line connected Mandapam on mainland India to Dhanushkodi. Boat mail express ran from Chennai Egmore to Dhanushkodi till 1964 w ...
