Plants survived the dinosaur-killing asteroid by duplicating genomes, study suggests
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.

ALnavío66 million years ago, an asteroid the size of Mount Everest hit the Earth and ended all non-avian dinosaurs and nearly a third of life on the planet, but many plants survived the devastation. Now, a study reveals how. The research, published this Friday in Cell Press magazine, reveals that accidental duplications of genomes — a natural phenomenon — could have helped many flowering plants overcome and adapt to the most extreme environmental perio…
