 Physical map of Earth with political borders as of 2016 Geography (from Greek: γεωγραφία, geographia, literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of the Earth and planets. The first person to use the word γεωγραφία was Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. Geography is often defined in terms of two branches: human geography and physical geography. Human geography deals with the study of people and their communities, cultures, economies, and interactions with the environment by studying their relations with and across space and place. Physical geography deals with the study of processes and patterns in the natural environment like the atmosphere, hydrosphere, biosphere, and geosphere. Featured article

Things you can doFeatured biographyAlfred Russel Wallace was a British naturalist, explorer, geographer, anthropologist, and biologist. He is best known for independently proposing a theory of natural selection which prompted Charles Darwin to publish on his own theory. Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago, where he identified the Wallace Line that divides Indonesia into two distinct parts, one with animals more closely related to those of Australia and the other with animals more closely related to those found in Asia. He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of bio-geography". Wallace was one of the leading evolutionary thinkers of the 19th century who made a number of other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. These included the concept of warning coloration in animals, and the Wallace effect, a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridization. An account of his observations, The Malay Archipelago, is regarded as probably the best of all journals of scientific exploration published during the 19th century.
