As ""Leakey's luck"" would have it, an enthusiastic portrait that takes a respectful stance but which doesn't ignore the range of criticism. The Kenyan boyhood, initiation into the Kikuyu tribe (without details), and an English public school and Cambridge education mark him as a promising, individualistic figure. His ""luck""--that remarkable propensity for finding fossils--is, however, just a starting point for anthropological theory. After more than thirty years turning up evidence in Olduvai Gorge, he startled a lot of archaeologists by contending that hominids were alive 19 million years ago (rather than the widely held belief in from 10 to less than one million). Although most scientists disagree with him (which the text acknowledges), Leakey is a tenacious sort and he has uncovered far more evidence than most. (In fact, Olduvai sounds rather like a family backyard.) Somewhat effusive, but sapient.
