Abstract
In order to study the origin of metazoans, we have compared sequences from the 5' end of the large subunit ribosomal RNA of a number of protists, fungi, plants and metazoans, including all diploblastic phyla (sequences of 10 new species have been determined, including that of the placozoan, Trichoplax adhaerens). These sequences were analyzed using distance matrix, maximum parsimony and maximum likelihood methods, and the validity of the results was ascertained with bootstrapping and species removal or addition. Triploblasts and diploblasts formed two clearly separated monophyletic units; this divergence, which apparently preceded the diversification of diploblastic animals (i.e. the successive sponge, ctenophore, cnidarian radiations), showed a much more ancient origin of triploblasts with respect to diploblasts than classically assumed. These results do not exclude the possibility that triploblasts and diploblasts arose independently from different protists.
摘要
为了研究后生动物的起源，我们比较了许多原生生物、真菌、植物和后生动物的大亚基核糖体RNA 5'端的序列，包括所有双胚层门（已确定了10个新物种的序列，包括扁盘动物黏丝盘虫的序列）。使用距离矩阵、最大简约法和最大似然法对这些序列进行了分析，并通过自展检验以及物种去除或添加来确定结果的有效性。三胚层动物和双胚层动物形成了两个明显分开的单系类群；这种分化显然发生在双胚层动物多样化之前（即海绵动物、栉水母动物、刺胞动物的相继辐射演化），表明三胚层动物相对于双胚层动物的起源比传统假设的要古老得多。这些结果并不排除三胚层动物和双胚层动物独立地从不同原生生物演化而来的可能性。
