Over the last two centuries the fossil record has revealed at least 15 different species of ancient human ancestors reaching back 6 million years into the past. But this only scratches the surface of the archaeological record. New finds can, and frequently do, result in significant rewrites of whole chunks of our evolutionary story. Fossil DNA, deep oceanfloor sediments, ice cores and Ice Age art are just some of sources that are helping to reveal the driving forces behind our early evolution and spread across the globe. This book brings together these sources to chart the deep past of the human race.
