Hairy fogfruit (Phyla nodiflora minor)
Description
The term phylum was coined by Haeckel from the Greek , "race, stock," related to ---- phyle, "tribe, clan." In plant taxonomy, Eichler (1883) classified plants into five groups named divisions, a term that remains in use today for groups of plants, algae and fungi. The definitions of zoological phyla have changed from their origins in the six Linnaean classes and the four "embranchements" of Georges Cuvier.Informally, phyla can be thought of as groupings of organisms based on general specialization of body plan.At its most basic, a phylum can be defined in two ways: as a group of organisms with a certain degree of morphological or developmental similarity (the phenetic definition), or a group of organisms with a certain degree of evolutionary relatedness (the phylogenetic definition).Attempting to define a level of the Linnean hierarchy without referring to (evolutionary) relatedness is unsatisfactory,[why-] but a phenetic definition is useful when addressing questions of a morphological nature-such as how successful different body plans were.
