Neutral evolution, intended to cover for the failures of Darwinian evolution (natural selection), is now being challenged by selectionists: Selection isn’t in doubt, but many scientists have argued that most evolutionary changes appear at the level of the genome and are essentially random and neutral. Adaptive changes groomed by natural selection might indeed sculpt a fin […]

New findings challenge the “neutral” theory of evolution for 95% of human genome
The neutral theory of evolution holds that “most variation at the molecular level does not affect fitness and, therefore, the evolutionary fate of genetic variation is best explained by stochastic [random] processes.” From ScienceDaily: However, what scientist Fanny Pouyet and colleagues from the Group of Laurent Excoffier at the SIB Swiss Institute of Bioinformatics and […]
