Talk:Molecular evolution

From Wikipedia, the free encyclopedia

This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy. If you would like to participate, there are some suggestions on this page (see also Wikipedia:Contributing FAQ for more information) or visit WikiProject Evolutionary biology.

The article could benefit from a figure and a section on evolutionary models in bioinformatics, e.g. evolutionary look-back horizon in sequence comparison, point accepted mutations and PAM matrix extrapolations etc. - tameeria 19:11, 18 February 2007 (UTC)

[edit] '04 comment

The article on molecular evolution should mention concrete basic mechanisms, such as mutation and gene duplication early on. Etxrge 07:26, 26 Oct 2004 (UTC)

Agreed, feel free to expand in summary style. --Lexor|Talk 08:08, Dec 13, 2004 (UTC)

A semantic nit: can "drift" of nonfunctional DNA sequences be called "evolution", if it does not lead to better fitness in the evolutionary sense? -130.233.136.69 Mon Dec 13 08:30:52 EET 2004

Yes, because evolution is usually defined a "change in allele frequencies" which can be caused by many factors (drift, mutation, gene flow, selection) only one of these (selection) will necessarily result in an increase in fitness. See the relevant section in the evolution article. --Lexor|Talk 08:08, Dec 13, 2004 (UTC)

[edit] New intro paragraph

The previous intro paragraph was perhaps a better description of molecular population genetics, a sister field. The new paragraph adds a discussion of protein evolution, and provides a historical account of the development of the field to the current day.NatMor 05:45, 20 March 2006 (UTC)
