Especially in small populations, these DNA expansions can accumulate via the powerful, non-adaptive influence of genetic drift. In multicellular organisms, which have smallish population sizes, it is more difficult for selection to remove mildly deleterious DNA accumulation.<br /><br />Michael Lynch lays this out in his book 'The Origins of Genome Architecture'.Mike Whitehttp://thefinchandpea.comnoreply@blogger.comtag:blogger.com,1999:blog-37148773.post-61531616330783809442012-09-18T17:59:57.362-04:002012-09-18T17:59:57.362-04:00The article is ‘Refuge of spandrels’(1999, Current...The article is ‘Refuge of spandrels’(1999, Current Biology) and you can find it (free) here: <a href="http://www.sciencedirect.com/science/article/pii/S0960982298704270" rel="nofollow">http://www.sciencedirect.com/science/article/pii/S0960982298704270</a>Claudiu Bandeahttps://www.blogger.com/profile/04987489537796352657noreply@blogger.comtag:blogger.com,1999:blog-37148773.post-46439229859883018892012-09-18T11:22:06.807-04:002012-09-18T11:22:06.807-04:00Can you point to an article by Brenner where he ta...Can you point to an article by Brenner where he talks about this?

Many people don't get this."</i><br /><br />Count me among the many. Could you expand on this?jeffnoreply@blogger.com
