Take a look at a very long timeline that shows the drama of life from the earliest single-celled organisms to the most powerful predators and finally to humans. Each species has been affected by changes in the temperature, the environment, and the relentless march of natural selection. Look at how huge extinctions, huge evolutionary bursts, and global changes have shaped our modern environment. Fossils are reminders of worlds that no longer exist.

Find the strong links between razor-sharp ocean hunters, towering land-based colossi, and our own ancestors, who all lived in environments that were always changing and faced danger and success. We learn more about how complicated, resilient, and able to change nature is by bringing old bones back to life and keeping track of every success and failure. This is the story of how life on Earth keeps changing and surviving, from the tiniest microbe to the biggest monster and everything in between.
