Re: Phylocode



Cladistic Taxonomy is defintely the most correct to classify the living
beings, but there's a problem...it is utopic.
A Cladistic analysis will only be "perfect" when ALL species, fossil and
extant, will be discovered, and we will have a complet cladogram. But this
will never happen.
