eroare // Din articol rezulta ca o echipa de cercetatori din Australia au spart pietre si au descoperit cum au aparut animalele!?

E prost scris articolul // Poate e mai clar aici: "We crushed these rocks to powder and extracted molecules of ancient organisms from them," said Dr Brocks from the ANU Research School of Earth Sciences. "These molecules tell us that it really became interesting 650 million years ago. It was a revolution of ecosystems, it was the rise of algae." "Before all of this happened, there was a dramatic event 50 million years earlier called Snowball Earth," he said. "The Earth was frozen over for 50 million years. Huge glaciers ground entire mountain ranges to powder that released nutrients, and when the snow melted during an extreme global heating event rivers washed torrents of nutrients into the ocean." Dr Brocks said the extremely high levels of nutrients in the ocean created the perfect conditions for the rapid spread of algae. It was the transition from oceans being dominated by bacteria to a world inhabited by more complex life, he said. "These large and nutritious organisms at the base of the food web provided the burst of energy required for the evolution of complex ecosystems, where increasingly large and complex animals, including humans, could thrive on Earth," Dr Brocks said.
