Traveling back again to the Turkana Basin felt great. The Basin is a frontier on many fronts. It is home to pastoralists, who eke out a living from a region characterized by arid scrubland and desert. It also represents the leading edge of scientific research into the origins of humans and the evolutionary history of modern fauna. Nowhere else on the planet is the fossil record of the Pliocene and Pleistocene epochs as well controlled and continuous as in the Turkana Basin. The fossil record contains specimens of each of the major lineages of human ancestors and provides strong evidence of a spurt of adaptive radiation in hominin species around 2.5 million years ago.
