The Geological Timeline tells, through words and pictures, the story of the Earth from its formation 4600 million years ago to the present day. It describes the key events in the evolution of life, from its earliest stages to the emergence of humans, and goes on to consider what the future may hold for the Earth’s environment and all its inhabitants. The Geological Timeline can be viewed online or as free download.
