Gabon found remains of the most ancient multicellular beings


The first metaphytes lived in the seas about 2.1 billion years ago. Earlier scientists believed that they appeared only 600-650 million years ago. In Gabon paleontologists found remains of the most ancient multicellular living beings living in the seas about 2.1 billion years ago. Their photos were published in the PNAS magazine on February 11. "Approximately in the same time there was one of the major events in the history of Earth, Great oxygen accident. We argue long ago on whether they are connected among themselves. Our fossils, despite divergences with data of geneticists, can speak well for similar communication", − noted Donald Kenfield from the Center of studying of evolution of Earth in Odense (Denmark) and his colleagues. Scientists believe that life could appear on Earth already three billion years ago, however she spent the first 2.5 billion years of the existence only in a monocelled form. The first multicellular beings presumably appeared only 600-650 million years ago, during the Ediacaran Period. Their life is almost not known as almost completely there are no remains. The unusual structures found in the breeds of the Paleoproterozoic Era created in the neighborhood of the city of Fransvill about 2.1 billion years ago drew attention about six years ago when scientists from Poitiers university found a set of the fancy structures similar to prints of bodies of multicellular animals here. Opening caused a lot of a controversy. A part of colleagues considered finds of the French paleontologists traces of "usual" bacterial colonies of an unusual form, and others in general denied their organic origin. Despite criticism, scientists continued to conduct excavation in the territory of Gabon. For the next years they found several new prints of various presumably "multicellular" beings similar in a form to threads and foliate structures. Two years ago Kenfield and its colleagues were lucky – they managed to find not only eight dozens fossilized remains, but traces of their movements on the bacterial "blankets" covering then a bottom of shallow water in primary ocean of Earth. Photo: pnas.org Having studied their structure and the chemical composition, scientists proved that foliate fossils really comprise traces of organic chemistry and the substances characteristic for эукариот, multicellular inhabitants of Earth. "It is not clear yet whether these organisms a peculiar prelude for further evolution эукариот or the unfortunate experiment which did not receive continuation were. On the other hand, they anyway say that irregular shapes of life appeared for one billion years before the first real animals appeared at the end of the Neoproterozoic", – paleontologists emphasize. Scientists found the most ancient overland organism Earlier was reported that in Antarctica during the research of the subglacial Lake Merser, scientists found a huge number of remains of live organisms.
