How four tools enabled humanity to control its destiny What enabled us to go from simple stone tools to smartphones? How did bands of hunter-gatherers evolve into multinational empires? Listeners of Sapiens will say a cognitive revolution - a dramatic evolutionary change that altered our brains, turning primitive humans into modern ones - caused a cultural explosion. In Transcendence, Gaia Vince argues instead that modern humans are the product of a nuanced coevolution of our genes, environment, and culture that goes back into deep time.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.
