我们对文多比昂塔王国作为真后生动物的单系姐妹群提供另一种解释。我们假设 Vendobionta 是类似刺胞动物的生物，但缺乏刺胞动物科。刺胞动物被认为是通过与小孢子虫共生获得刺胞动物而产生的。我们的分析与现有对埃迪卡拉化石作为现存刺胞动物祖先的解释不同，因为我们不认为这些形式中的任何一种是息肉类或水母类。这种解释需要建立一个新的后生动物门，Vendobionta。
We offer an alternative interpretation of the Kingdom Vendobionta as a monophyletic sister group to the Eumetazoa. We hypothesize that the Vendobionta are cnidarian-like organisms that lacked cnidae. Cnidarians are held to have arisen by acquisition of cnidae by symbiosis with a microsporidian. Our analysis differs from existing interpretations of the Ediacaran fossils as ancestors of extant cnidarians in that we do not regard any of these forms as either polypoid or medusoid. This interpretation requires the erection of a new metazoan phylum, the Vendobionta.
