Polyphyletic
A polyphyletic Taxon is a Taxon defined by a resemblance which was not inherited a common ancestor. This term indicates tax which does not have any relevance to recall the family ties and thus the evolution. It is indeed necessary for that to use the method Cladistique. It can be a question of a term of the current language indicating a whole of species presenting of the common characters, but gathering of this fact of the clades of varied origins; such a taxon can also rise from a scientific concept invalidated by the analysis Phylogénétique even by the traditional systematic .
The fomation of these groups makes it possible more to describe a common lifestyle and adaptations, resulting from a evolutionary Convergence.
