Complex life billion years earlier than thought?
From the Guardian: Fossils from China are said to prove that multi-cellular organisms evolved as early as 1.5bn years ago – but some experts dismiss findings “Our discovery pushes back nearly one billion years the appearance of macroscopic, multi-cellular eukaryotes compared to previous research,” said Maoyan Zhu, a professor at the Nanjing Institute of Geology and Palaeontology. The fossils were uncovered in the Yanshan region of Hebei province in China. Zhu and colleagues said they had found 167 measurable fossils, a third of them in one of four regular shapes – an indication of complexity. The largest measured 30cm by 8cm. Taken together they were “compelling evidence for the early evolution of organisms large enough to be visible with the Read More ›
