Multiregional Origin Of Modern Humans
The multiregional hypothesis is a scientific model that provides an explanation for the pattern of human evolution. The hypothesis holds that humans first arose near the beginning of the Pleistocene two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses archaic human forms such as Homo erectus and Neanderthals as well as modern forms, and evolved worldwide to the diverse populations of modern Homo sapiens sapiens. The theory contends that humans evolve through a combination of adaptation within various regions of the world and gene flow between those regions. Proponents of multiregional origin point to fossil and genomic data and continuity of archaeological cultures as support for their hypothesis.
The primary alternative model, which is the predominant position held in the scientific community, is the recent African origin of modern humans, which holds that modern humans arose in Africa around 100,000–200,000 years ago, moving out of Africa around 50,000–60,000 years ago to replace archaic human forms with limited interbreeding: one with Neanderthals and one with Denisovans.

Famous quotes containing the words humans, modern and/or origin:
“Here we also see: what this divinity lacks is not only a sense of shame—and there are also other reasons for conjecturing that in several respects all of the gods could learn from us humans. We humans are—more humane.”
—Friedrich Nietzsche (1844–1900)
“Merely external emancipation has made of the modern woman an artificial being.... Now, woman is confronted with the necessity of emancipating herself from emancipation, if she really desires to be free.”
—Emma Goldman (1869–1940)
“The real, then, is that which, sooner or later, information and reasoning would finally result in, and which is therefore independent of the vagaries of me and you. Thus, the very origin of the conception of reality shows that this conception essentially involves the notion of a COMMUNITY, without definite limits, and capable of a definite increase of knowledge.”
—Charles Sanders Peirce (1839–1914)
