Just a new evolutionary note: more evidence that birds did not descent from dinosaurs, but perhaps a common ancestor. http://www.sciencedaily.com/releases/2009/06/090609092055.htm What is most interesting to me with my backgroud in exercise physiology (my fellowship) is that arm work in humans costs three times more blood flow than leg work, implying three times more oxygen consumption. Did we get this from the birds?
