As far as humanity knows, life on Earth has experienced two great explosions of biodiversity. The first happened hundreds of millions of years ago, during the Cambrian Period. The second took place in 2023. It made no sense and could not be explained by science, like some prank by God. After the explosion began, the genetic activity of every living thing doubled. This sharply increased the likelihood of mutations, bringing disasters no one had anticipated. From an infinitesimal possibility, a miraculous catastrophe was eventually born.
Every species began evolving at an astonishing rate, as if the god who created the world had compressed the history of animal evolution from tens of millions of years into a mere few. Humanity had already conquered the Earth, but now terrifying animals struck back.
