ven though the NAS blindly defends the theory of evolution in its
                      booklet Science and Creationism and suggests that there is defini-
                      tive evidence for the theory in all fields, it has also admitted in its
              publication Proceedings of the National Academy of Sciences (PNAS) that
              the theory contains a number of contradictions. An essay entitled "The
              New Animal Phylogeny: Reliability and Implications," published in the
              April 25, 2000 issue of PNAS, is just one of many articles full of such con-
              fessions.
                  Another essay, prepared by scientists from France's Centre National
              de la Recherche Scientifique (CNRS), details how unreliable and contra-
              dictory evolutionary family trees are, and expresses the need for new the-
              ories to be produced. The following statements appear in the article:
                  DNA sequence analysis dictates new interpretation of phylogenic
                  trees. Taxa that were once thought to represent successive grades of
                  complexity at the base of the metazoan tree are being displaced to
                  much higher positions inside the tree. This leaves no evolutionary "in-
                  termediates" and forces us to rethink the genesis of bilaterian com-
                  plexity.
                  Worst of all, contradictory trees have kept pouring in, often with in-
                  sufficient critical assessment.
                  Such a rapid splitting of lineages appears to have occurred repeatedly
                  during evolution, and it renders reconstruction of the order of splits
                  very difficult even with large amounts of sequence data.
                  The new molecular based phylogeny has several important implica-
                  tions. Foremost among them is the disappearance of "intermediate"
                  taxa between sponges, cnidarians, ctenophores, and the last common
                  ancestor of bilaterians or "Urbilateria."
                  ...A corollary is that we have a major gap in the stem leading to the
                  Urbilataria. We have lost the hope, so common in older evolutionary
