Última Foundational errors in the Neutral and Nearly-Neutral theories of evolution in relation to the Synthetic Theory: Is a new evolutionary paradigm necessary? Biol. Res. Valenzuela,Carlos Y. The Neutral Theory of Evolution (NTE) proposes mutation and random genetic drift as the most important evolutionary factors. The most conspicuous feature of evolution is the genomic stability during paleontological eras and lack of variation among taxa; 98% or more of nucleotide sites are monomorphic within a species. NTE explains this homology by random fixation of neutral bases and negative selection (purifying selection) that does not contribute either to evolution or polymorphisms. Purifying selection is insufficient to account for this evolutionary feature and the Nearly-Neutral Theory of Evolution (N-NTE) included negative selection with coefficients as low as mutation rate. These NTE and N-NTE propositions are thermodynamically (tendency to random... Tipo: Journal article Palavras-chave: Fixation; Loss; Neutral evolution; Polymorphism; Randomness; Selectiveness.
