Dipnoi (phylogenetic classification)

Introduction

This page has the aim of presenting a Phylogenetic tree Dipnoi, i.e. a tree clarifying the complex evolutionary relations (relations ancestral groups - downward groups) existing between the various living organisms, or taxed, component this group. Because of its new methods based on molecular biology, the Phylogeny, recent science at the origin of the phylogenetic Classification of alive, is in full rise and sometimes in contradiction with old the traditional Classification, mainly based, it, on morphological and physiological criteria. Also, certain particular points are sometimes still the debate object within the scientific community. The objective, if it is necessary, is also to present the latter ici.
This tree presents the still existing organizations as well today as the extinct groups (including the fossil groups).
