Scientists discover that the oldest ancestor of man is like an ugly objects

Chinese fossils scientists found traces of primitive multicellular organisms that resemble a serrated bags.

It is noteworthy that the majority of the ancestors of contemporary forms of animals appeared on the face of the earth since about 540-520 million years ago, in the era of so-called "Cambrian explosion", when accelerated multi-cellular organisms suddenly diversity process. And it appeared in this time the ancestors of worms, insects, fish and other vertebrates.

The so-called "dual-mouth animals' ancestors to humans, wildlife and fish, which is currently represented by sea stars and hedgehogs, but the rest of the multi-cell animals, they belong to the oral preliminary animal species.

The bilateral animals differ from the preliminary oral mouth to anus replace mouth when Ttoraganan, where it becomes the mouth embryonic Hrja, the new mouth Vickl in the other party to the animal, which aroused the interest of scientists.

And try a researcher at the Chinese North West University (Degan Shaw) and his colleagues to find a solution to that question, and after that they found in the mountainous rocks that formed in the Cambrian explosion, the fossilized traces tiny object ovoid millimeters and one long era, and is similar to the object bag a serrated parties, and they shot him naming "Saccorhytus coronarius".

Did scientists first unable to locate in charge of the animal, and after analyzing dozens of fossils have reached to the conclusion that there is no Hrja, it means that the fossils scientists were able to discover the oldest dual-mouth animal, which essentially put the evolution of the animal and the human world in the ground later.
