Q: What is a list of animal phyla?
A: A list of animal phyla is a list of the major groups of animals usually classified as a phylum.
Q: How can such a list be arranged?
A: Such a list may be arranged alphabetically or according to evolutionary relationships.
Q: Are all lists completely satisfactory?
A: No, not all lists are completely satisfactory due to differing opinions on what constitutes a phylum and the actual name of the phylum.
Q: What techniques have been used to reduce differences in opinion about evolutionary relationships?
A: Techniques such as molecular evolution, molecular clock research, protein amino acid sequences, and whole genome DNA sequence analysis have been used to reduce differences in opinion about evolutionary relationships.
Q: How has traditional comparative anatomy impacted classification?
A: Traditional comparative anatomy had errors which needed to be corrected; for example, the old phylum Coelenterata was split down into two separate phyla, the Cnidaria and the Ctenophora.
Q: What is this list based on?
A: This list is based on evolutionary relationships.
