New study reveals role of ancient asteroid impact in today s rainforests After the asteroid impact that killed the dinosaurs, flowering plants took over tropical forests.  April 13, 2021 Tropical rainforests today are biodiversity hotspots and play an important role in the world s climate systems. A new U.S. National Science Foundation-funded study published in Science sheds light on the origins of modern rainforests and may help scientists understand how rainforests will respond to a rapidly changing climate in the future. The project, led by scientists at the Smithsonian Tropical Research Institute, shows that the asteroid impact that ended the reign of dinosaurs 66 million years ago also caused 45% of plants in what is now Colombia to go extinct. But it made way for the reign of flowering plants in modern tropical rainforests.
