The Evolutionary Road to Human Memory

We tend to think about memory in terms of our own experience, but a series of our direct ancestors—from the earliest vertebrates to archaic humans—also had memories. The evolutionary history that we share with these ancestral species has left its mark on modern memory, complemented by other forms of memory that are uniquely human. This book traces the long evolutionary road to human memory by explaining how a series of now-extinct ancestral species adapted to life in their world, in their time and place. As they did, new brain areas appeared, each of which supported an innovative form of memory that helped them gain an advantage in life. Through inheritance and modification across millions of years, these evolutionary novelties created several kinds of memory that influence the human mind today. Then, during human evolution, yet another new kind of memory emerged: about ourselves and others. This evolutionary innovation ignited human imagination; empowered us to remember and talk about a personal past; and enabled the sharing of knowledge about our world, our cultures, and ourselves. Through these developments, evolution made it possible for every individual, day upon day, to add new pages to the story of a life: the remarkable, rich record of experiences and knowledge that make up a human mind.
