Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal.
Movement on appendages is the most common form of terrestrial locomotion, it is the basic form of locomotion of two major groups with many terrestrial members, the vertebrates and the arthropods. Important aspects of legged locomotion are posture (the way the body is supported by the legs), the number of legs, and the functional structure of ...
Eomaia ("dawn mother") is a genus of extinct fossil mammals containing the single species Eomaia scansoria, discovered in rocks that were found in the Yixian Formation, Liaoning Province, China, and dated to the Barremian Age of the Lower Cretaceous about 1]
Scansoriopterygidae (meaning "climbing wings") is an extinct family of climbing and gliding maniraptoran dinosaurs.Scansoriopterygids are known from five well-preserved fossils, representing four species, unearthed in the Tiaojishan Formation fossil beds (dating to the mid-late Jurassic Period) of Liaoning and Hebei, China.
In West Africa, the wet phase ushered in an expanding rainforest and wooded savanna from Senegal to Cameroon. Between 9000 and 5000 BC, Niger–Congo speakers domesticated the oil palm and raffia palm. Two seed plants, black-eyed peas and voandzeia (African groundnuts), were domesticated, followed by okra and kola nuts. Since most of the plants ...
Brachiation (from "brachium", Latin for "arm"), or arm swinging, is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. During brachiation, the body is alternately supported under each forelimb.
African historiography became organized at the academic level in the mid-20th century. [263] Members of the Ibadan School, such as Kenneth Dike and Saburi Biobaku, pioneered a new methodology of reconstructing African history using the oral traditions, alongside evidence from European-style histories and other historical sciences.
Ancestors of the Khoisan may have expanded from East Africa or Central Africa into Southern Africa before 150,000 BP, possibly as early as before 260,000 BP. [2] [3] Due to their early expansion and separation, ancestors of the Khoisan may have been the largest population among anatomically modern humans, from their early separation before 150,000 BP until the Out of Africa migration in 70,000 BP.
