Bold numbers indicate strong differences (+/-25%) to Limulus polyphemus (underlined). This species was chosen for comparison, because in the phylogenetic analyses (Fig. 3, 4) it shows a branch length comparable to those of crustacean, myriapod and hexapod species, while the remainder of chelicerates was subject to a higher degree of nucleotide substitution. See methods for complete names of species.
