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 ...
The Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene. The Pleistocene lasted from 2.58 million to 11,700 years ago.
According to the Pangaea Proxima model created by Christopher R. Scotese, a new subduction zone will open in the Atlantic Ocean and the Americas will begin to converge back toward Africa.

Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". [ 1 ] Cultural evolution is the change of this information ...
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 ...
The multiregional hypothesis, multiregional evolution (MRE), or polycentric hypothesis, is a scientific model that provides an alternative explanation to the more widely accepted "Out of Africa" model of monogenesis for the pattern of human evolution. Multiregional evolution holds that the human species first arose around two million years ago ...
The supercontinent Pangaea in the early Mesozoic (at 200 Ma) surrounded by Panthalassa. The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago. Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [ 1 ...
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
