In Lucy’s Legacy, a charming, eclectic and sensible book, [Jolly] argues that while evolution certainly involves competition, the major transitions have arisen through cooperation… With humor and erudition she leads the reader to an understanding of the biology and behavior of primates, through the evolution of intelligence and into ‘the age of humanity,’ where evolution is charted chiefly by the human mind. Her genius in this informative, satisfying book is to strip away dogma and politics that have shrouded evolution, to reveal a theory Darwin would recognize as his own. ‘There is grandeur in this view of life,’ he wrote, and here it is seen marvelously.
