Deep sea 'mushroom' may be new branch of life
"The new organisms are multicellular but mostly non-symmetrical"So it's not really a new branch of life if it's multicellular but just non-symmetrical ...Maybe a new sub-division in the multicellular kingdom but not a whole new branch at the same level as bacteria, archaea and multicellulars...edit : bacteria, archae and EUKARYOTE not multicellular
