Despite their fragile, gelatinous bodies, fossils thought to represent ctenophores – apparently with no tentacles but many more comb-rows than modern forms – have been found in Lagerstätten as far back as the early Cambrian, about 515 million years ago. Nevertheless, a recent molecular phylogenetics analysis concludes that the common ancestor originated approximately 350 million years ago ± 88 million years ago, conflicting with previous estimates which suggests it occurred 66 million … WebThe cellular aggregate level organisation can be seen in Spongilla which belongs to phylum Porifera. Tissue level organisation can be seen in Obelia as they have simple tissues which perform the metabolic function. Organ system-level organisation can be seen in Pheretima where the specialised organ is developed for metabolic activity.
