A coherent theory of neutral evolution was first proposed by Motoo Kimura in 1968 [9] and by King and Jukes independently in 1969. [10] Kimura initially focused on differences among species; King and Jukes focused on differences within species. Many molecular biologists and population geneticists also contributed to the development of the ...
The Neutral Theory of Molecular Evolution is an influential monograph written in 1983 by Japanese evolutionary biologist Motoo Kimura.While the neutral theory of molecular evolution existed since his article in 1968, [1] Kimura felt the need to write a monograph with up-to-date information and evidences showing the importance of his theory in evolution.
The neutral theory of molecular evolution, proposed by Motoo Kimura in 1968, holds that at the molecular level most evolutionary changes and most of the variation within and between species is not caused by natural selection but by genetic drift of mutant alleles that are neutral.
Neutral evolution can therefore be visualised as a population diffusing from one set of sequence nodes, through the neutral network, to another cluster of sequence nodes. Since the majority of evolution is thought to be neutral, [ 14 ] [ 15 ] a large proportion of gene change is the movement though expansive neutral networks.
Constructive neutral evolution is a competitor for both adaptationist explanations for the emergence of complex traits and hypotheses positing that a complex trait emerged as a response to a deleterious development in an organism. [2]
According to Ohta, however, the nearly neutral theory largely fell out of favor in the late 1980s, because of the mathematically simpler neutral theory for the widespread molecular systematics research that flourished after the advent of rapid DNA sequencing. As more detailed systematics studies started to compare the evolution of genome ...
Non-Darwinian Evolution" is a scientific paper written by Jack Lester King and Thomas H. Jukes and published in 1969. It is credited, along with Motoo Kimura's 1968 paper "Evolutionary Rate at the Molecular Level", with proposing what became known as the neutral theory of molecular evolution.
