Higher vertebrates generally have a central nervous system and/or brain, or take the negative of that, sponges are the most primitive multicellular animal phylum, lacking a nervous system; cnidarians (true jellies, coral etc) are next up the ladder and while they have a nervous system lack a true brain; while insects in the next major group up the ladder (protostomes) have a brain, deuterostomes next up the ladder include the vertebrates (amphibians, reptiels, birds, mammals etc)
