This is of course bad news for any life on Planet Earth. Although some species will no doubt survive, the impact will likely mark the end of the age of mammals – the current Cenozoic Era – and instead usher in a new age of complex life forms.
Who knows what sort of life will thrive on this newly purged Earth? Perhaps one day we’ll be sharing the universe with intelligent invertebrates or amphibians. For now though, our imagination is the only limit as to what may occur.
