The social and natural sciences have more in common than most people would perhaps suspect. This thought-provoking study, the first of its kind ever attempted, presents a single straightforward structure which unites the latest scientific views on the history of the Universe, the Solar System, Earth, life and humankind. It contributes to a better understanding of some long-standing academic controversies, such as the root causes for the origins of humankind, the rise of agriculture and the emergence of early states.
