Polygenism is a theory of human origins which posits the view that the humans are of different origins (polygenesis).This view is opposite to the idea of monogenism, which posits a single origin of humanity.
All women have evolved to be beautiful, in an illustration by Paul Merwart for a 1911 edition of Camille Flammarion's 1894 novel La Fin du Monde.. Evolution has been an important theme in fiction, including speculative evolution in science fiction, since the late 19th century, though it began before Charles Darwin's time, and reflects progressionist and Lamarckist views as well as Darwin's.

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 ...
Polygenic adaptation describes a process in which a population adapts through small changes in allele frequencies at hundreds or thousands of loci. [ 1 ] Many traits in humans and other species are highly polygenic , i.e., affected by standing genetic variation at hundreds or thousands of loci.
A polygene is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait, thus contributing to multiple-gene inheritance (polygenic inheritance, multigenic inheritance, quantitative inheritance [1]), a type of non-Mendelian inheritance, as opposed to single-gene inheritance, which is the core notion of ...
The geneticist Dan Koboldt observes that while science and technology play major roles in fiction, from fantasy and science fiction to thrillers, the representation of science in both literature and film is often unrealistic. [28] In Koboldt's view, genetics in fiction is frequently oversimplified, and some myths are common and need to be debunked.
Future of human evolution is considered a classic theme, harkening to H.G. Wells' The Time Machine and its division of the human race into two subspecies, the Eloi and the Morlocks. Many later works build on this idea, exploring futures in which humans themselves evolve into post-material forms of energy or software, and this theme. [2] [3] [4]
In critical theory, the posthuman is a speculative being that represents or seeks to re-conceive the human.It is the object of posthumanist criticism, which critically questions humanism, a branch of humanist philosophy which claims that human nature is a universal state from which the human being emerges; human nature is autonomous, rational, capable of free will, and unified in itself as the ...
