The case of the missing neutrality | Russell K. Standish
; | Date: |
27 Dec 2003 | Journal: | Proceedings ACAL 2003, Abbass, H.A. and Wiles, J. (eds), ISBN 0975152807, p209 | Subject: | Adaptation and Self-Organizing Systems; Populations and Evolution | nlin.AO q-bio.PE | Abstract: | The concept of neutral evolutionary networks being a significant factor in evolutionary dynamics was first proposed by Huynen {em et al.} about 7 years ago. In one sense, the principle is easy to state -- because most mutations to an organism are deleterious, one would expect that neutral mutations that don’t affect the phenotype will have disproportionately greater representation amongst successor organisms than one would expect if each mutation was equally likely. So it was with great surprise that I noted neutral mutations being very rare in a visualisation of phylogenetic trees generated in {em Tierra}, since I already knew that there was a significant amount of neutrality in the Tierra genotype-phenotype map. The paper reports on an investigation into this mystery. | Source: | arXiv, nlin.AO/0401039 | Services: | Forum | Review | PDF | Favorites |
