In Systematic, a Taxon is monophyletic when it gathers exactly all the descendants of the same ancestor. The presence of derived characters common to different let us tax (called then derived characters clean or Synapomorphie S ) allows to gather those under the same name, representative of the character monophyletic of the group. For example, the presence of a core in the cells of the Eucaryote S.
