Have I understood that right?<br /><br />(BTW, sorry for still not having replied to your responses to my comment a few threads and weeks ago.

I just discovered your campaign when I saw your post on Research Blogging, but I've read all the previous posts, before creating my response.<br /><br />I've posted my <a href="http://artksthoughts.blogspot.com/2009/06/paraphyly.html" rel="nofollow">response</a> on my own blog, where you're welcome to comment, or answer here.<br /><br />Just to summarize, however, IMO the study of the evolutionary <b>process</b> can sometimes make very good use of paraphyletic groups.AKhttps://www.blogger.com/profile/10905636789614137068noreply@blogger.com
