Fossils of oldest multi-cellular organism found

The researchers, writing in the journal Nature Communications, said they had uncovered fossils showing that complex life on Earth began more than 1.5bn years ago.
•    After first emerging from the primordial soup, life remained primitive and single-celled for billions of years, but some of those cells eventually congregated like clones in a colony. 
•    Scientists took to calling the later part of this period the “boring billion” because evolution seemed to have stalled.
•    Previously, eukaryotes of comparable size had not been known to appear in the fossil record until about 600m years ago, when a multitude of soft-bodied creatures inhabited the world’s oceans.
•    Their very existence 1.56bn years ago would mean that “oxygen levels were sufficiently high to allow for such large organisms to subsist”.
•    Antcliffe suggested the fossils were more likely corresponded to colonies of bacterial cells, rather than a single complex organism.
•    Truly multicellular creatures display three-dimensional form in which only some cells are in direct contact with the environment.
