Following four intensely competitive international teams of scientists in a heated race to find the “missing link”–the fossil of the earliest human ancestor–Gibbons ventures to Africa, where she encounters a fascinating array of fossil hunters: Tim White, the irreverent Californian who discovered the partial skeleton of a primate that lived 4.4 million years ago in Ethiopia; French paleontologist Michel Brunet, who uncovers a skull in Chad that could date the beginnings of humankind to seven million years ago; and two other groups–one led by zoologist Meave Leakey, the other by British geologist Martin Pickford and his French paleontologist partner, Brigitte Senut–who enter the race with landmark discoveries of their own. Through scrupulous research and vivid first-person reporting, The First Human reveals the perils and the promises of fossil hunting on a grand competitive scale.
