Noile dovezi din Mongolia care demonstrează că animalele vertebrate au apărut cu 200 de milioane de ani mai devreme

A new analysis of fossils from China and Mongolia suggests that the first vertebrate animals appeared 200 million years earlier than previously thought. Researchers found genetic evidence indicating that the first animal life emerged around 800 million years ago, challenging the established theory that animals evolved during the Ediacaran period. Fossils from the Doushantuo formation in China and the Kheseen biota in Mongolia show well-preserved microscopic marine organisms but lack animal fossils, suggesting that early animals may have evolved earlier than the Ediacaran. The study indicates that the absence of animal fossils does not prove they did not exist at that time, and researchers propose looking for early animal evidence in other regions.
