Tiny ancestor of man

Maybe you should not take it so seriously, but our oldest ancestor was not smashing beautifull. Scientists announced yesterday that a tiny marine from China conquered the bottom of the sea 540 million. years ago may be the first member in the great evolutionary path that eventually led to the appearance of man. It was a paradox being that, for its size, had a huge mouth. The paleontologist of the University of Cambridge Simon Conway Morris notes that people who walked on earth two hundred thousand years ago have some evolutionary ancestors and are not apes and large primates. And among them the so-called “Sakorchytos”. The Sakorchytos, whose length is one-thousand seems to be the oldest example among so-called “defterostomon” category to which they belong and many vertebrate creatures, fish, amphibians, birds and mammals, echinoderms such as starfish and sea urchins, and many other species. He lived in Kamvriani period and features that had paved the way for the emergence of many defterostomon, among which vertebrate beings. The fish appeared about 10-15 million. years after Sakorchyto. “Our Sakorchytos opens a real window on the first phase of the evolutionary path that led to the creation of fish, and eventually to the emergence of the human race,” says paleontologist Deng Su of the Chinese University of Northwestern.

Fossils of about 40 such beings, kept in excellent condition, found in the province of Shaanxi in central China. The Sakorchytoi lived like little black spores in sediments in shallow seas. With the enormous mouth of the Sakorchytos it seems that it could consume large amounts of food or smaller creatures. Researchers also failed to find traces indicate that these beings had a**s and hence the release of superfluous materials were orally. The study published in the journal Nature.
