Neutral theory: a historical perspective [PDF]
Journal of Evolutionary Biology, 2007 AbstractTo resolve a panselectionist paradox, the population geneticist Kimura invented a neutral theory, where each gene is equally likely to enter the next generation whatever its allelic type. To learn what could be explained without invoking Darwinian adaptive divergence, Hubbell devised a similar neutral theory for forest ecology, assuming each ...

The neutral theory is dead. Long live the neutral theory
BioEssays, 1996AbstractThe neutral theory of molecular evolution has been instrumental in organizing our thinking about the nature of evolutionary forces shaping variation at the DNA level. More importantly, it has provided empiricists with a strong set of testable predictions and hence, a useful null hypothesis against which to test for the presence of selection ...

A neutral theory of biogenesis
Origins of Life, 1981The selective Darwinian theory of chemical evolution is critically reviewed and the tentative conclusion is reached that neither the theoretical analyses nor the experiments with phages can really prove it. An alternative proposal is put forth which considers the possibility that the biogenetic process has been driven by stochastic forces, e.g. it took

The neutral theory in the genomic era
Current Opinion in Genetics & Development, 2001A number of tests have been developed to detect positive selection at the molecular level. These tests are based on DNA polymorphism within and divergence between species. Applications of these tests have revealed a large collection of genes that have evolved under positive selection and some general insights into adaptive evolution.

Abstract The neutral theory claims that the great majority of evolutionary changes at the molecular (DNA) level are caused not by Darwinian selection but by random fixation of selectively neutral or nearly neutral mutants. The theory also asserts that the majority of protein and DNA polymorphisms are selectively neutral and that they ...

Reasons are given for rejecting the current theory of neutralization, and a new theory which represents the experimental procedure more exactly is propounded. It is shown that the test should be made with a large separation between the test object and the observer's eye, and that the connection between the vertex powers of the lenses when ...

AbstractComparative studies of DNA sequences provide opportunities for testing the neutral and the selection theories of molecular evolution. In particular, the separate estimation of the numbers of synonymous and nonsynonymous substitutions is a powerful tool for detecting selection of the latter.

Evolutionary constraints and the neutral theory
Journal of Molecular Evolution, 1984The neutral theory of molecular evolution postulates that nucleotide substitutions inherently take place in DNA as a result of point mutations followed by random genetic drift. In the absence of selective constraints, the substitution rate reaches the maximum value set by the mutation rate.

MY INTEREST for this evening, you may rest assured, is only that interest which has to do with theory. The practical question of neutrality has been settled for us for the present. The historical and philosophical aspect of neutrality is therefore our field of discussion.

The neutral theory in an infinite population
Gene, 2000Selective substitutions at one locus induce stochastic dynamics at a linked neutral locus that resemble genetic drift even when the population size is infinite. This new stochastic force, which is called genetic draft, causes genetic variation at the neutral locus to decrease with population size and the rate of deleterious substitution to increase ...
