Monophyletic in Biological Definition

Cladistics

... make use of cladistic techniques, but allow both monophyletic and paraphyletic groups as taxa . A monophyletic group is a clade, comprising an ancestral form ... are as harmful as polyphyly. The idea is that monophyletic groups can be defined objectively, in terms of ...

Animal

... do not have a permanent digestive chamber. The remaining animals form a monophyletic group called the Bilateria . For the most part, they are bilaterally ... All this suggests the deuterostomes and protostomes are separate, monophyletic lineages. The main phyla of deuterostomes are the Echinodermata and ...

Bacterium

... Gram-negative stains The archeabacteria were originally included as the Mendosicutes. As given, these phyla are no longer believed to represent monophyletic groups. The Gracilicutes have been divided into many different phyla. Most gram-positive bacteria are placed in the phyla Firmicutes and ...

Monophyletic

... In phylogenetics , a group is monophyletic ( Greek : of one stem ) if all organisms in that group are known to have developed from a common ancestral form, and all descendants of that form ...

Paraphyletic

... most recent common ancestor of all group members. Groups which include all the descendants of the most recent common ancestor are commonly termed monophyletic or holophyletic . The former is more common, but sometimes paraphyletic groups are also considered monophyletic, in which case the latter is used. ...

Plant

... from green algae; the two are collectively referred to as the green plants or Viridaeplantae. The kingdom Plantae is now usually taken to mean this monophyletic group, as shown above. With a few exceptions among the green algae, all such forms have cell walls containing cellulose and chloroplasts ...

... Except for the ciliates and water moulds, the traditional groups are polyphyletic and frequently overlap. Newer systems attempt to provide monophyletic groups based on ultrastructure , chemistry, and genetic features. However, an understanding of the evolutionary relationships between protists has ...
