University of Texas at Austin researchers found that microscopic plankton species evolved within 2,000 to 11,000 years after the asteroid impact that killed the dinosaurs 66 million years ago, using helium-3 isotope measurements to refine sediment dating. The discovery suggests life rebounded far faster than previously believed, with 10 to 20 new foraminifera species appearing within roughly 6,000 years of the Chicxulub impact.
