Molecular evolutionary clock and the neutral theory. The neutral theory of molecular in 1968 motoo kimura introduced the concept and discipline вґneutral theory of molecular evolutionвґ , nature 217:624-626, evolutionary rate at the molecular level., the neutral theory can be contrasted with the idea that almost all molecular evolution has been driven by natural selection. the difference between the two ideas can be understood in terms of the frequency distribution for the selection coefficients of mutations, or genetic variants..

The neutral theory is shorthand for the theory that at the molecular level evolutionary changes and polymorphisms are mainly due to selectively neutral mutations; thus, their behaviour and fate are determined by mutation and random drift. the theory explains polymorphism as a transient phase of molecular evolution, and demands a dichotomy between molecular and phenotypic evolution. the neutral theory of molecular evolution however, the high levels of polymorphism can explained without encountering excessive genetic load simply by dropping the assumption that natural selection is the driving force of molecular

The theory - which asserts that the great majority of evolutionary changes at the molecular level are caused not by darwinian selection but by random drift of selectively neutral mutants - has caused controversy ever since. this book is the first comprehensive treatment of this subject and the author synthesises a wealth of material - ranging from a historical perspective, through recent neutral theory of molecular evolution вђў describes the source of variation in natural populations вђў the majority of genetic differences between two populations are neutral

The Neutral Theory of Molecular Evolution by Motoo Kimura. Summary. from the standpoint of the neutral theory of molecular evolution, it is expected that a universally valid and exact molecular evolutionary clock would exist if, for a given molecule, the mutation rate for neutral allelesper year were exactly equal among all organisms at all times. While the neutral theory was proposed specifically to explain dna and protein sequence evolution, the impact of the neutral theory is beyond the field of molecular evolution. for evolutionary biologists, neutrality is commonly considered the null hypothesis against which adaptation is tested even in studies of phenotypic evolution. recent investigations of large numbers of molecular traits.

    In this perspective, we evaluate the explanatory power of the neutral theory of molecular evolution, 50 years after its introduction by kimura. we argue that the neutral theory was supported by unreliable theoretical and empirical evidence from the beginning, and that in light of modern, genome-scale data, we can firmly reject its universality. the ubiquity of adaptive variation both within the neutral theory of molecular evolution in the genomic era masatoshi nei, yoshiyuki suzuki, and masafumi nozawa annual review of genomics and human genetics detecting natural selection in вђ¦
