The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Evolution of Neanderthals. 300 ka Gigantopithecus, a giant relative of the orangutan from Asia dies out. 250 ka Anatomically modern humans appear in Africa. [103] [104] [105] Around 50 ka they start colonising the other continents, replacing Neanderthals in Europe and other hominins in Asia. 70 ka Genetic bottleneck in humans (Toba catastrophe ...
[111] [112] In September 2019, scientists reported the computerized determination, based on 260 CT scans, of a virtual skull shape of the last common human ancestor to modern humans (H. sapiens), representative of the earliest modern humans, and suggested that modern humans arose between 260,000 and 350,000 years ago through a merging of ...
The only human fossils found before the discovery of Java Man in the 1890s were either of anatomically modern humans or of Neanderthals that were too close, especially in the critical characteristic of cranial capacity, to modern humans for them to be convincing intermediates between humans and other primates.
The image has become better-known than the science behind it. [3] With regard to the way the illustration has been interpreted, the anthropologist and author of the section, F. Clark Howell, remarked: [6] The artist didn't intend to reduce the evolution of man to a linear sequence, but it was read that way by viewers. ...
The gene microcephalin (MCPH1), involved in the development of the brain, likely originated from a Homo lineage separate from that of anatomically modern humans, but was introduced to them around 37,000 years ago, and has become much more common ever since, reaching around 70% of the human population at present.
Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as Homo erectus , Denisovans , and Neanderthals as well as modern forms, and evolved worldwide to the diverse ...
The modern synthesis [a] was the early 20th-century synthesis of Charles Darwin's theory of evolution and Gregor Mendel's ideas on heredity into a joint mathematical framework. Julian Huxley coined the term in his 1942 book, Evolution: The Modern Synthesis .
