Talk:Stem group

This section says,  “A stem group lies basally to a crown group, consisting of its most closely related living relatives.” . The article, Crown group contradicts this. There is says, ”Because the Dodo, although extinct, is still descended from the last common ancestor of all living birds, for example, it is nevertheless included in the bird crown group.” Please sort this out.Barbara Shack (talk) 13:42, 8 January 2008 (UTC)
