The oldest animal was discovered, possessing muscle

A petrified creature discovered in Canada may be the most the ancient animal known to science, which possessed muscles. it a fossil estimated to be over 560 million years old is considered relative of anemone and jellyfish. His muscle tissue contained fibrous bundles that played a large role in adaptation animal to environmental conditions. Study co-author Alex Liu (a paleontologist from Cambridge University in England), said that the fossils of an ancient creature found are direct confirmation that muscle organisms lived on our planet much earlier than 560 million years ago. Before that, scientists believed that the evolution of animals began about 540 million years ago, during the so-called “Cambrian explosion.” This time is considered a period. rapid development of life, because it was then that most of the main groups of animals first appeared in the fossil record. However over the past decades, researchers have discovered even more complex fossils and traces of animal activity at the end Ediacar period, which occurred around 580 – 541 million years back. The idea that animals first appeared long ago is “cambria”, also confirmed by many studies. In the process of analysis scientists repeatedly compared the genetic data of various animals to not only determine how strong temporary discrepancies of their conclusions, but also in order to calibrate “molecular clock”. This watch is gradually becoming more and more more accurate. Now, according to some estimates of chemical fossil compounds, it is assumed that animals for the first time arose about 700 million years ago. Most fossils Ediacar period do not have obvious features that would clearly identified them as animals, not plants, fungi, or other life forms. However, a new fossil found in Newfoundland (Canada) is significantly different from all others fossils of that time. The creature’s body resembled a round disk. Apparently, this body structure helped the fossil. fixed at the bottom of the ocean. The disc was connected to four short leaf-shaped legs consisting of fibrous muscle bundles. This fossil represents a new species of the so-called Haootia quadriformis. Scientists have classified it as a type of hydroid water animals, which includes corals, sea anemones and jellyfish. Researchers Exclude Other Possible Explanations of Education bundles of fibers, because the complexity and location of their bundles they only say that these are really muscles that resemble bundles in the muscle tissue of modern intestinal organisms.
