When an asteroid as big as Mount Everest struck Earth 66 million years ago, it wiped out all non-avian dinosaurs and roughly a third of life on the planet. But many plants survived the devastation. In a new study published in Cell, researchers reveal that the accidental duplications of genomes—a natural phenomenon—might have helped many flowering plants survive some of the most extreme environmental upheavals in Earth's history.
