Early Human World

Today's most urgent problems are fundamentally global. They require nothing less than concerted, planetwide action if we are to secure a long-term future. But humanity's story has always been on a global scale. Sachs takes listeners through a series of seven distinct waves of technological and institutional change, starting with the original settling of the planet by early modern humans through long-distance migration and ending with reflections on today's globalization.

Red is a brilliantly told, captivating history of red hair throughout the ages. An audiobook that breaks new ground, dispels myths, and reinforces the special nature of being a redhead, with a look at multiple disciplines, including science, religion, politics, feminism and sexuality, literature, and art. With an obsessive fascination that is as contagious as it is compelling, author Jacky Colliss Harvey (herself a redhead) begins her exploration of red hair in prehistory and traces the redhead gene as it made its way out of Africa with the early human diaspora.

Technically speaking, slavery was not legal in the English-speaking world before the mid-17th century. But long before race-based slavery was entrenched in law and practice, English men and women were well aware of the various forms of human bondage practiced in other nations and, in less systematic ways, their own country. In wide-ranging detail, Slaves and Englishmen demonstrates how slavery shaped the ways the English interacted with people and places throughout the Atlantic world. As this revealing history shows, the implications of slavery were closely connected to the question of what it meant to be English.

Most scientists believe the evolution of humans has a history nearly as long as life itself. Anatomically modern humans and all other life that has existed on the planet first came about from the single-celled microorganisms that emerged approximately four billion years ago. Through the processes of mutation and natural selection, all forms of life developed, and this continuous lineage of life makes it difficult to say precisely when one species completely separates from another.
