The nearly neutral theory of molecularevolution is a modification of the neutral theory of molecularevolution that accounts for slightly advantageous or deleterious mutation s at the molecular level. The nearly neutral theory was proposed by Tomoko Ohta in 1973 ref name Ohta 1973 Cite journal doi 10.1038 246096a0 volume 246 issue 5428 pages 96 98 last Ohta first Tomoko title Slightly Deleterious Mutant Substitutions in Evolution journal Nature date 1973 11 09 pmid 4585855 ref including only deleterious mutations and expanded in the early 1990s to include both advantageous and deleterious nearly neutral mutations. Unlike in Motoo Kimura s original neutral theory&mdash which dealt only with mutations unaffected by natural selection &mdash the nearly neutral theory predicts a relationship between population size and the rate of molecularevolution in larger populations, genetic drift , which can bring even slightly deleterious mutations to Fixation population genetics fixation , is a weaker force, so evolution happens more slowly than in smaller populations.

Merge Cluster chemistry date May 2010 Unreferenced date March 2010 Atomic clusters Atomic and molecular clusters are aggregates of 5 10 sup 5 sup atomic or molecular units. They classify according to the forces holding them together Van der Waals clusters attraction between induced electric dipoles and repulsion between electron cores of closed electronic configurations Metallic clustes long range valence electron sharing over many successive adjacent atoms and partially directional Ionic clusters valence electrons are almost entirely transferred among closest neighbors to yield 2 net, equal but opposite, electric charge distributions that mutually attract. Quantum many body mechanisms are also important. The role of cluster formation in the precipitation of liquid mixtures and in the condensation , adsorbtion adsorption to surface or Freezing solidification phase transitions has been long investigated from a theoretical standpoint. Cluster system properties stem both from their size and composition which contributes to the binding force types that determine the number of dimensions of their phase space the ranges of accessible positions and velocities of their atomic components A gradual transition occurs between the properties of the molecular species and those of the corresponding bulk mix. And yet the clusters exhibit physical and chemical properties specific only to their configuration space in turn strongly atom count dependent and not specific to their bulk counterparts. Cluster systems are metastability metastable with respect to at least one of the following evolution classes atom elimination or adsorption at cluster surface as a cause for their disassociation or growth configuration switches among a set of stable structures a.k.a. an isomer class accessible to all clusters of a same atom count and a same relative component composition. A large fraction of their component ... molecular forces to find global minimum configurations that hold at least one interior molecule ... more details
