Jellyfish comb (comb jelly) turned out much earlier than the sponge, which has been labeled as the first animal in the world. The conclusions drawn from the results of the DNA traces tracking is quite surprising to scientists because it shows that the first animal is more complex than previously thought.
So surprising because we initially thought that large errors occur, "said Casey Dunn of Brown University who reported the findings in a recent issue of the journal Nature. Latest Temua ensure that the comb jellyfish into other sources of animal development. Mysteries appearance of animals on Earth is still leaving much a mystery until now. best method to do is to study trace fossils and comparing it with the genetic nature of the animals are still alive.
The difference between the DNA code of the other animals with a reference to construct the history of the origins of these organisms. Chimpanzees and humans, for example, have similar genetic and 98 percent is estimated to come from the same ancestor millions of years ago apart To trace the history of the animal, the scientists compared the DNA data of various types of animals and develop genetic tree.
The latest findings show that the comb jellyfish turns occupying the top of the tree genetics. Although the name of jellyfish, the animal is not a true jellyfish because it does not have a stinger as a weapon. However, the comb jellyfish has had a complex organ, such as connective tissue and nervous system. Nevertheless Dunn findings of this study is not the final round. Of the approximately 10 million living creatures are thought to exist on Earth, a new 1.8 million species identified. There are still many unsolved mysteries of life.
