From Homer to Star Wars humans have been driven by quest. Ever since man first walked he has sought for food and shelter, for knowledge, for wealth, and adventure. It has been the driving force behind human development, the inspiration for exploration, for discovery and for the development of great civilisations. It is in man’s very nature to seek, not just for basic needs or personal comfort, but also beyond his own requirements or those of his generation - to climb mountains because they are there, to study and experiment for the sake of knowledge, and to voyage to the moon and beyond.

In this epic work Charles Pasternak traces life on earth from the most primitive cells, through ancient civilizations and the great artists, scientists, writers and explorers of the past, to the genetic engineers of today. In a thought-provoking view of the history of mankind he argues that it is not any single genetic difference, but a combination of very subtle changes that has enabled man to exercise a greater propensity for quest. It is this that has led to our domination over other species.

Conversely, he argues that a weakening in the exercise of this basic instinct among the western nations will lead to a decline in their influence, relative to that of eastern populations such as those of China and India, south east Asia and Japan.

An intriguing work of history, philosophy, and popular science that explores the human desire to quest.

Scientists continually look for the genetic factors that make humans so very different in appearance and behaviour from most animals - the genes that are uniquely human. Respected biochemist and author Charles Pasternak argues that such genes do not exist. Instead, he suggests that it is our desire to quest - for food and shelter, for knowledge, for wealth, for adventure - coupled with our unique physical abilities to do so that have controlled our evolution and have led humans to develop away from closely related animals.

In this intriguing work of history, philosophy, and popular science, Pasternak uses his extensive biological knowledge to discuss man's nature and achievements, his genetic makeup, and his evolution.

In What Makes Us Human? some of the world's most brilliant thinkers offer their answers to this perennial puzzle, including Susan Blackmore, Robin Dunbar, Richard Harries, Kenan Malik and Lewis Wolpert. Together they draw on a broad spectrum of disciplines, from anthropology, medicine, and neuroscience, to philosophy, psychology and religion, to ask what makes us distinctively human. Is it our cognitive abilities, our use of tools, our story-telling, our beliefs, our curiosity, our ability to cook, or our culture?
