Step back in time and experience Earth history like never before. The award-winning Deep Time Walk is a ground-breaking tool enabling anyone, anywhere to take a walking audio history of our planet.

• Learn about key concepts from Earth’s long evolution including how Earth formed, the evolution of life, plate tectonics, oxygenic photosynthesis, multicellular life, The Cambrian Explosion, vertebrates, plants, amphibians, mammals, dinosaurs and finally (in the last 20cm) humans.

• Understand our species common ancestral heritage and interconnectedness with all life.

• Comprehend the ecological impact of humans in the blink of a geological eye.

• Time-contextual glossary available to review key scientific concepts.

• Mobility-assist mode available for those unable to walk.

• Use the What's Next portal for positive action (with organisations such as Earth Charter and 350.org).
