The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately seven million years, [ 1 ] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
The evolution of eukaryotes, and possibly sex, is thought to be related to the GOE, as it probably pressured two or three lineages of prokaryotes (including an aerobe one, which later became mitochondria) to depend on each other, leading to endosymbiosis. Early eukaryotes lost their cell walls and outer membranes.
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
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 discovery challenged the idea that humans evolved in a neat line from primitive to complex and underscored just how much remained unknown about the human story.
Pithecometra: In the frontispiece from his 1863 Evidence as to Man's Place in Nature, Huxley compared skeletons of apes to humans.. The Pithecometra principle or Pithecometra thesis (German: Pithecometra-Satz) describes the evolution of humans; the pithecometra law is analogous to the concept that "man evolved within apes" or "man descended from apes" as advocated by Thomas Henry Huxley.
