phylumlevel
Phylum level, also referred to simply as phylum, is a primary taxonomic rank in biological classification that sits below the kingdom and above the class. It is used to group organisms into broad evolutionary lineages that share fundamental structural and developmental traits. In zoology, phyla unite vastly different organisms such as chordates, arthropods, and mollusks. In botany, the corresponding rank is often called division; some systems still use phylum for plants, though division is more common in current practice.
Members of a phylum are typically characterized by major body plans or developmental features, but there is
Modern phylum boundaries are increasingly informed by molecular data. Morphology, embryology, and genetic analyses are used
