Mass extinction occurred about 2 billion years ago, which destroyed up to 99.5% of life on Earth, scientists say. It killed more of the Earth's biosphere than the event that caused dinosaurs to disappear 65 million years ago, according to a study released last week and reported by Newsweek on Monday.

Researchers used geochemical data from rocks in subarctic Canada to track atmospheric oxygen decline. After what they call the GOE event, researchers say that in the next 1 billion years, "from holiday" to "starvation" has changed

"An unprecedented decrease in the geosphere in the biosphere has occurred in the "19009006]" In the 100 to 200 million years before this dying event there was a great life on the planet, but after that event a huge part died, "Peter Crockford, author of the study, told Newsweek." According to our estimates, it could be anywhere between 99.5% and 80% of the life on the planet that died about 2 years ago iarda years. "
