Very possibly the same will happen with this book, and it isn't just the colugos and tree shrews. The position of tarsiers (Rendezvous 7), and the grouping of lampreys with hagfishes (Rendezvous 22) are unsure. The affinities of the afrotheres (Rendezvous 13) and the coelacanths (Rendezvous 19) are still slightly unsure. The ordering of our rendezvous with cnidarians and ctenophores (Rendezvous 28 and 29) could be the wrong way round.
很可能本书也会同病相怜，这不仅仅是因为猫猴和树鼩——跗猴的位置（见第7纪），以及七鳃鳗和八目鳗类鱼的分组（见第22纪）尚不能确定；远古非洲哺乳动物（见第13纪）和腔棘鱼类（见第19纪）的亲缘关系也有待商榷；而我们在刺丝胞动物和栉水母类（见第28纪和第29纪）章节的编排上也许也是一个错误。
