Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.
Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [1]
The encephalization quotient of some cetaceans is therefore higher than that of most primates, including the nearest relatives of humans, such as Australopithecus. [8] This list follows partly from Walter Carl Hartwig's 2002 book The Fossil Primate Record [9] and John G. Fleagle's 2013 book Primate Adaptation and Evolution (3rd edition). [10]
Primatomorpha is a subdivision of Euarchonta including primates and their ancestral stem-primates Plesiadapiformes. An early stem-primate, Plesiadapis, still had claws and eyes on the side of the head, making it faster on the ground than in the trees, but it began to spend long times on lower branches, feeding on fruits and leaves.
Evolution of the creodonts, an important group of meat-eating (carnivorous) mammals. 62 Ma Evolution of the first penguins. 60 Ma Diversification of large, flightless birds. Earliest true primates, [who?] along with the first semelid bivalves, edentate, carnivoran and lipotyphlan mammals, and owls.
The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1]
They classified Homo and all bipedal apes in the subtribe Hominina and Pan in the subtribe Panina. (Wood (2010) discussed the different views of this taxonomy.) [2] A "chimpanzee clade" was posited by Wood and Richmond, who referred it to a tribe Panini, which was envisioned from the family Hominidae being composed of a trifurcation of ...
Sir Wilfrid Le Gros Clark was one of the primatologists who developed the idea of trends in primate evolution and the methodology of arranging the living members of an order into an "ascending series" leading to humans. [7] Commonly used names for groups of primates such as prosimians, monkeys, lesser apes, and great apes reflect this methodology.
