For some years a number of authors (e.g. Seilacher 1984, McMenamin 1986) were able to argue, convincingly, that the Ediacarans were unrelated to any living group of organisms; that they represented a new kingdom (Vendobionta Seilacher 1992) which was wiped out by a mass extinction event at the Vendian-Cambrian boundary. However, much of the ‘evidence’ supporting this view has been over-turned by the discovery of Edicaran assemblages persisting into the Cambrian and of morphologically similar forms which clearly are animals. This view has now lost most of its support. (Emphasis mine)
Note the quote postdates 1992, which means it's more up-to-date than the material you quoted. And, it appears to contradict your assertion that Cambrian life sprang full-blown from nothing and thus obviated evolution.
They mean "non-creationist support," of course!
