Organisms17
  • Informally, phyla can be thought of as groupings of organisms based on general specialization of body plan. (wikipedia.org)
  • 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). (wikipedia.org)
  • citation needed] The most important objective measure in the above definitions is the "certain degree" that defines how different organisms need to be members of different phyla. (wikipedia.org)
  • The minimal requirement is that all organisms in a phylum should be clearly more closely related to one another than to any other group. (wikipedia.org)
  • The definition was posited because extinct organisms are hardest to classify: they can be offshoots that diverged from a phylum's line before the characters that define the modern phylum were all acquired. (wikipedia.org)
  • A greater problem is that it relies on a subjective decision about which groups of organisms should be considered as phyla. (wikipedia.org)
  • The approach is useful because it makes it easy to classify extinct organisms as "stem groups" to the phyla with which they bear the most resemblance, based only on the taxonomically important similarities. (wikipedia.org)
  • Furthermore, organisms in the stem group of a phylum can possess the "body plan" of the phylum without all the characteristics necessary to fall within it. (wikipedia.org)
  • In contrast, phylum Echinodermata includes organisms that show pentamerous radial symmetry. (differencebetween.com)
  • Phylum annelid includes bilaterally symmetrical segmented worms while phylum Echinodermata includes radially symmetrical marine organisms. (differencebetween.com)
