The Origin and Evolution of Animals (Metazoa), Site devoted to the Cnidaria with illustrations. From the chart on page 52, it would appear that protostome and deuterostome were simultaneous events; but apparently, there was a 60 million year difference between the split from protostome to deuterstome. , Determining Protostome or deuterostome for phyla? Segmentation is common among most chordates, which just means that the organism is separated into different parts usually for specialization like the creation of a head cavity for a brain. Subjects. Moreover, there is a possibility that Ambulacraria can be the sister clade to Xenacoelomorpha, and form the Xenambulacraria group.[12][13][14].

As a member, you'll also get unlimited access to over 84,000 After the formation of the anus, another cavity called archenteron runs through the gut, leading to the formation of the mouth in deuterostomes. [8] The phylum Chaetognatha (arrow worms) may belong here,[7] but molecular studies have placed them in the protostomes more often.
