"We have found an unknown branch of the tree of life that lives in this lake. It is unique! So far we know of no other group of organisms that descend from closer to the roots of the tree of life than this species". This is the bold statment of Shalchian-Tabrizi and co-workers who report about evolutionary origin of the poorly studied protist Collodictyon by cDNA and rDNA sequencing. Results suggest that Collodictyon constitutes a new lineage in the global eukaryote phylogeny.
