摘要
Gene structure data can substantially advance our understanding of metazoan 演化 and deliver an independent approach to resolve conflicts among existing hypotheses. Here, we used changes of spliceosomal intron positions as novel 系統發育 marker to reconstruct the animal tree. This kind of data is inferred from orthologous genes containing mutually exclusive introns at pairs of sequence positions in close proximity, so-called near intron pairs (NIPs). NIP data were collected for 48 物種 and utilized as binary 基因組-level characters in maximum parsimony (MP) analyses to reconstruct deep metazoan phylogeny. All groupings that were obtained with more than 80% bootstrap support are consistent with currently supported 系統發育 hypotheses. This includes monophyletic Chordata, Vertebrata, Nematoda, Platyhelmint
