However, some recent studies demonstrated that urochordate sea squirt is the sister group of vertebrates instead of cephalochordates.In order to further elucidate the relationship in cephalochordates,urochordates and vertebrates and therefore,it is very essential for carting through transcriptome-wide analysis of amphioxusand comparating with sea Urchin and sea squirt.In addition,it would also provide an important foundation for further annotating and assembling of the forthcomingly publicized amphioxus genome.

When the first edition of this work was published, I was so completely deceived, as were many others, by such expressions as "the continuous operation of creative power," that I included Professor Owen with other palaeontologists as being firmly convinced of the immutability of species; but it appears ("Anat. of Vertebrates," vol. iii. p. 796) that this was on my part a preposterous error.
