Deep Time Walk

This phone application will take you on a 4.6km narrated walk through 4.6 billion years of the earth’s history, with each meter representing one million years. Learn how our planet evolved over this vast stretch of time, including the accretion of the Earth from a disc of rocky debris, the formation of the oceans and atmosphere, the appearance of bacteria, including the first life, then the first nucleated cells, and, eventually, multicellular organisms. As you walk, you begin to recognize the long geological processes and self-regulating patterns that have produced the conditions for the evolution of life.
