Scientists have unearth credible evidence to confirm a large asteroid was responsible for the extinction of the dinosaurs over 66 million years ago, it has been announced. This particular extinction event, which paved the way for the evolution of our species, has been attributed to several different things over the years. From climate change, a nuclear winter caused by basaltic lava eruptions of massive volcanoes in western India, an influx of radiation from a nearby supernova explosion (or perhaps a gamma-ray burst) to finally, an asteroid impact, which has been a favorite of biologist and paleontologist over the course of the past few decades.
