The ant colony based phylogeny on the 64vertebrates. Using the vertebrate dataset [8, 16], the ant colony based phylogeny is showed in fig. 5, we can see that the constructed phylogeny is largely consistent with the taxonomy tree showed in. For example, all perissodactyls, birds, reptiles, bony fish etc. are grouped together, as they showed in neighbour join based phylogeny and the taxonomy tree of . This demonstrates that our ant colony based phylogenies at least can equally performance with NJ based method. And from tables of experimental results we can easily find that ant colony based phylogeny has an advantage of easily computed and optimized results.
