There are approximately 30 animal phyla currently recognized. The last major group of the animal kingdom is known as phylum chordata. Chordates are animals having a cord, i.e., notochord. The animals belonging to all other phyla of the animal kingdom are often termed ‘the non-chordates’ or ‘the invertebrates’ since they have no notochord or backbone in their body structure. This book focuses on the evolutionary relationships of non-chordate animals.
