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. | |

[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)
[edit] Embryology
would sympathtic editors consider a positive vote here? [1]Slrubenstein | Talk 15:18, 23 August 2006 (UTC)
[edit] Infinite alleles model
I suggest that we make an article for the "Infinite alleles model". It's an important model, but it's a model of population genetic. -PhDP (talk) 18:44, 16 July 2007 (UTC)
[edit] Key researchers in molecular evolution, is this relevant ?
Is this section relevant ? First of all, there's nothing like that in the other important articles about evolution, and also, it seems subjectives. The important researchers will be quoted in the text anyway... I think we should remove it -PhDP (talk) 20:21, 22 July 2007 (UTC)
[edit] Causes of change in allele frequency
This has nothing to do in this article, molecular evolution is not about "allele frequency", again, this is population genetics, molecular evolution is more concerned about nucleotide substitution. In most intro. book about molecular evolution, there's a little paragraph about this, but the core of the book is about nucleotire substitution, this is how the article should be written. -PhDP (talk) 20:59, 22 July 2007 (UTC)
[edit] Connection with punctuated equilibrium
Neutral mutations do not affect the organism's chances of survival in its natural environment and can accumulate over time, which might result in what is known as punctuated equilibrium; the modern interpretation of classic evolutionary theory.
I don't know much about evolutionary biology, but this seems like complete BS to me.
- what might result in punctuated equilibrium? The accumulation of neutral mutations over time? Punctuated equilibrium is the rapid evolutionary change due to some sudden selection pressure. What has that got to do with some slow accumulation over time?
- punctuated equilibrium is "the modern interpretation of classic evolutionary theory"? Maybe one modern interpretation.
