Title: ?Is there a phylogenetic tree of all biological organisms.
Post by: paradigm on 29/04/2011 11:27:21

Is there a phylogenetic tree of all biological organisms from their original creation up until the present? Such a tree would cover the age of the Dinosaurs.

There is a phylogenetic tree posted on the internet which extends the 3 domains tree of Carl Woese, into 7 domains which covers the age of the Dinosarus.

It indicates that everything evolved from two types of mini-virus, which could be called the Last  Universal Common Ancestors (LUCA's).

Can this be right?
