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)
