Origins of society. Appearance. The origins of society — the evolutionary emergence of distinctively human social organization — is an important topic within evolutionary biology, anthropology, prehistory and palaeolithic archaeology. [ 1 ][ 2 ] While little is known for certain, debates since Hobbes [ 3 ] and Rousseau [ 4 ] have returned ...
Alfred Lothar Wegener (/ ˈveɪɡənər /; [ 1 ]German: [ˈʔalfʁeːt ˈveːɡənɐ]; [ 2 ][ 3 ] 1 November 1880 – November 1930) was a German climatologist, geologist, geophysicist, meteorologist, and polar researcher. During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research, but ...
Christopher R. Scotese (born 4 May 1953) is an American geologist and paleogeographer.He received his PhD from the University of Chicago in 1985. He is the creator of the Paleomap Project, which aims to map Earth over the last billion years, and is credited with predicting Pangaea Ultima, a possible future supercontinent configuration. [1]
Continental drift is the theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere.
They depict his interpretation of how the American and African continents may once have fit together before becoming separated. Antonio Snider-Pellegrini (1802–1885) was a French geographer and geologist who theorized about the possibility of continental drift, anticipating Wegener's theories concerning Pangaea by several decades.
Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists. Origin of the concept. Alfred Wegener c. 1924–1930World map of Pangaea created by Alfred Wegener to illustrate his concept. The name "Pangaea" is derived from Ancient Greekpan(πᾶν, "all, entire, whole") and Gaiaor Gaea (Γαῖα ...
First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana.. The Tethys Ocean (/ ˈ t iː θ ɪ s, ˈ t ɛ-/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early-mid Cenozoic Era.
Arthur Holmes FRS FRSE (14 January 1890 – 20 September 1965) was an English geologist who made two major contributions to the understanding of geology. He pioneered the use of radiometric dating of minerals, and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics.
