One theme has dominated the evolution of life on earth: the apparently simple act of moving from one place to another.
Matt Wilkinson traces this 4-billion-year history, showing why our ancestors became two-legged, how movement explains our opposable thumbs and our backbone, how fish fins became limbs, how even trees are locomotion-obsessed, and how movement has shaped our minds as well as our bodies. He explains how dinosaurs took to the air, how Mexican waves were the making of the animal kingdom, and why moving can actually make us feel good.
