Evolutionary trees based on partial small ribosomal subunit RNA sequences of 22 metazoa species have been published [(1988) Science 239, 748-753]. In these trees, cnidarians (Radiata) seemed to have evolved independently from the Bilateria, which is in contradiction with the general evolutionary view. In order to further investigate this problem, the complete srRNA sequence of the sea anemone Anemonia sulcata was determined and evolutionary trees were constructed using a matrix optimization method. In the tree thus obtained the sea anemone and Bilateria together form a monophyletic cluster, with the sea anemone forming the first line of the metazoan group.
基于22种后生动物物种的部分小核糖体亚基RNA序列构建的进化树已经发表[（1988年）《科学》239卷，748 - 753页]。在这些进化树中，刺胞动物（辐射对称动物）似乎是从两侧对称动物独立进化而来的，这与一般的进化观点相矛盾。为了进一步研究这个问题，测定了海葵光滑海葵的完整小核糖体RNA序列，并使用矩阵优化方法构建了进化树。在由此得到的进化树中，海葵和两侧对称动物共同形成一个单系类群，海葵构成了后生动物类群的第一分支。
