A zoologist at the Natural History Museum of Denmark in Copenhagen, Jean Just, discovered sea creatures in the Tasman Sea that cannot be classified into any known major phyla. These invertebrate 카지노 미국now classified as카지노 미국—are mushroom shaped, multicellular, asymmetrical, and have a gelatinous layer between the inner and the outer body. They seem to have morphological similarities to jellyfish and comb jellies.카지노 미국are also similar to a small group of 'medusoids,' jellyfish-like 카지노 미국, which lived 600 million years ago during the Ediacaran period. Thus, these 카지노 미국 could be descendants of the Ediacara organisms, which were thought to be extinct over 500 million years ago. Developmental biologists feel such animal lineages can help gather information about ancient mass extinction events and reconstruct the course of evolution.
