Another fact that puts evolutionists into a deep quandary about the Cambrian Explosion is the comparisons between different living taxa. The results of these comparisons reveal that animal taxa considered to be "close relatives" by evolutionists until quite recently, are genetically very different, which puts the "intermediate form" hypothesis, that only exists theoretically, into an even greater quandary. An article published in the Proceedings of the National Academy of Sciences in 2000 reports that DNA analyses have displaced taxa that used to be considered "intermediate forms" in the past:
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 "intermediates" and forces us to rethink the genesis of bilaterian complexity...37
In the same article, evolutionist writers note that some taxa which were considered "intermediate" between groups such as sponges, cnidarians and ctenophores can no longer be considered as such because of new genetic findings, and that they have "lost hope" of constructing such evolutionary family trees:
The new molecular based phylogeny has several important implications. 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 reasoning, of reconstructing the morphology of the "coelomate ancestor" through a scenario involving successive grades of increasing complexity based on the anatomy of extant "primitive" lineages.38
