600 It is thought that earliest multicellular life on Earth was a sponge-like creature. 
? Sponges are among simplest of animals, with partially differentiated tissues but without muscles, nerves, or internal organs.
Sponges ( Porifera) are phylogenetically oldest animal phylum extant today.
In some ways they are closer to being cell colonies than multicellular organisms.
