In it, Maynard Smith summarises work on evolutionary game theory that had developed in the 1970s, to which he made several important contributions. The book is also noted for being well written and not overly mathematically challenging. The main contribution to be had from this book is the introduction of the Evolutionarily Stable Strategy , or ESS, concept, which states that for a set of behaviours to be conserved over evolutionary time, they must be the most profitable avenue of action when common, so that no alternative behaviour can invade. So, for instance, suppose that in a population of frogs, males fight to the death over breeding ponds. This would be an ESS if any one cowardly frog that does not fight to the death always fares worse in fitness terms, of course . A more likely scenario is one where fighting to the death is not an ESS because a frog might arise that will stop fighting if it realises that it is going to lose. This frog would then reap the benefits of fighting, but not the ultimate cost. Hence, fighting to the death would easily be invaded by a mutation that causes this sort of informed fighting. Much complexity can be built from this, and Maynard Smith is outstanding at explaining in clear prose and with simple math ... evolution Category Game theory Category Evolutionary game theory Category Mathematics books Evolution ... game Honesty, bargaining and commitment The evolution of cooperation Postscript Appendices.

  1. Neutral mutation

    Unreferenced date December 2009 In genetics , a neutral mutation is a mutation that has no effect on Fitness biology fitness . In other words, it is neutral with respect to natural selection . For example, some mutations in a DNA triplet or codon do not change which amino acid is introduced this is known as a synonymous substitution . Unless the mutation also has a Regulation of gene expression regulatory effect, synonymous substitutions are usually neutral. Some non synonymous mutations, i.e. mutations that do change the amino acid, are also neutral these neutral changes are often to a chemically similar amino acid that works just as well. Such mutations may spread through genetic drift neutral drift . Neutral mutations can accumulate over time due to genetic drift or genetic hitchhiking genetic draft . According to the neutral theory of molecular evolution , while the majority of mutations are deleterious, the majority of mutations that go on to become fixed as differences between species are neutral. Many or even most mutations to noncoding DNA are neutral.
