Scientists simulated a skeleton of the fish, most ancient in the world


Her skull, according to the statements of experts, is surprising that it is halved by "an intra cranial joint". The Australian scientists conducted the research devoted to the oldest of the known species of fish on the planet. It gave them new ideas of evolution of land animals. They also simulated a skeleton of fish which has rare feature. Writes Nature of Fish about it treat a sort of latimeriya. According to experts, the skull of their fishes was halved by "an intra cranial joint". The first in modern history copy of this fish was caught in 1938 at coast of South Africa. They were considered as vypershy many millions years ago. Detailed studying of a skull of fish in the course of its formation gives the chance to understand evolution of animals. "We consider that formation of this special joint is probably caused by unique development of a notokhorda (the rod-shaped education which is taking place on a longitudinal axis of a body and serving as a temporary skeleton at embryos of all chordates). At fishes it usually degenerates in a small twig under a brain, and at a latimeriya on the contrary - increases to become in 50 times more of a brain", - researchers noted. Scientists for many years could not solve a riddle of the small size of a brain of latimeriya. They noted that while process of evolution of the person was followed by growth of a brain and drawing apart bones of a skull, at latimeriya absolutely excellent picture is observed. "Their brain almost does not grow, and the cavity is filled with a joint. Our research showed that peculiar "joint" is formed in a skull of fish of a cartilaginous core or a notokhorda, and it prevents ossification of a skull of a latimeriya"", - professor John Long noted. This opening, according to the researcher, is unique, and allows to look at evolution of vertebrata in a new way. Earlier it was reported that scientists established advantage of a breakfast - as it appeared, it can save from heart attack. News from the Correspondent.netv of Telegram.
