The evolutionary order of invertebrate phyla are sponges, cniderians, and bilaterians. The origin of invertebrate phyla begin in the Precambrian times.
There are many phyla of invertebrates. Please click on the related link below to see an article that lists the invertebrate phyla.
It will stress the evolutionary relationships between different phyla.
phylum mollusca
Platyhelminthes
All invertebrates except Porifera possess nervous system .
There are more than two phyla in the animal kingdom... There are many phyla in the animal kingdom. There are a few phyla of worms and other invertebrates and then you have the vertebrate ohyla. Unless that's what your asking? Did you want the invertebrate and vertebrate in general phyla? That's the only set of 2 things I can think of.
The only common groups for them would be the Doman Eukaryia and the kingdom Animalia, beyond that they are separated into a number of invertebrate phyla; those phyla being every single animal phyla except for Chordata.

Perhaps the most significant evolutionary trend among the metazoan invertebrate phyla is that of cephalization. This term refers to the development of a head, containing a brain. Another process called segmentation allowed animals to develop distinct body parts, such as legs, wings and feelers.
the order of the phyla are porifera,annelida Cnidaria,and Echinodermata and many more.
