Study: Asteroid that wiped out dinosaurs shaped fortunes of snakes

“Snakes owe their success in part to the asteroid strike that wiped out the dinosaurs, according to a new study. The impact caused devastation, with most animals and plants dying out. But scientists say a handful of surviving snake species were able to thrive in a post-apocalyptic world by hiding underground and going long periods without food. The resilient reptiles then spread out across the globe, evolving into the 3,000 or more species known today. The dinosaurs famously died out when an asteroid hit the Earth 66 million years ago, triggering earthquakes, tsunamis and wildfires, followed by a decade of darkness when ash clouds blocked out the Sun. An estimated 76% of plants and animals disappeared. But snakes, like some other mammals, birds, frogs and fishes, managed to cling on to life.” (09/14/21)
