Astonishing new research suggests that 470 million years ago, an enormous collision in the Asteroid Belt, which orbits the sun between Mars and Jupiter, bombarded the Earth with meteorites. That bombardment may have resulted in the single greatest increase in biological diversity on the planet since life began. Introducing these revolutionary discoveries to the general public for the first time, Nield challenges the view that meteorites are bad news for life on Earth while tracing their history from the first recorded strike to the videos made routinely today. Here is the perfect introduction to the science and history of the falling sky.
