New York, Nov 27 (Ians) Earth is currently in the middle of a mass extinction, losing thousands of species each year and new research suggests environmental changes caused the first such event in history, which occurred millions of years earlier than scientists previously thought.
Most dinosaurs famously disappeared 66 million years ago at the end of the Cretaceous period.
Prior to that, a majority of Earth’s creatures were snuffed out between the Permian and Triassic periods, roughly 252 million years ago.
According to researchers at University of California-Riverside (Ucr) and Virginia Tech, a similar extinction occurred 550 million years ago, during the Ediacaran period.
Although unclear whether this represents a true “mass extinction”, the percentage of organisms lost is similar to these other events, including the current, ongoing one, said researchers in a paper published in the Proceedings of the National Academy of Sciences.
