Abstract

The article discusses new research revealing that microscopic marine organisms known as planktic forams rebounded much more quickly after the asteroid impact that caused the mass extinction event 66 million years ago than previously thought. Earlier studies estimated that new foram species emerged approximately 30,000 years post-impact, but recent findings suggest they began to proliferate as early as 2,000 years after the event. This research utilized helium isotopes from sediment layers, which provided a more accurate timeline for the recovery of marine ecosystems. The findings challenge previous assumptions about the pace of life’s recovery following catastrophic environmental changes. [Extracted from the article]
