"There is no scientist today whose books I look forward to reading with greater anticipation of enjoyment and enlightenment than Stephen Jay Gould."—Martin Gardner Among scientists who write, no one illuminates as well as Stephen Jay Gould doesthe wonderful workings of the natural world. Now in a new volume of collected essays—his sixth since Ever Since Darwin—Gould speaks of the importance of unbroken connections within our own lives and to our ancestralgenerations. Along with way, he opens to us the mysteries of fish tails, frog calls, and other matters, and shows once and for all why we must take notice when a seemingly insignificant creature is threatened, like the land snail Partula from Moorea, whose extinction he movingly relates.

This collection of essays ranges from history to the latest theories in biology, from controversies over palaeontology to the origins of language. The title is a pun and as always with Gould, the joke has a point that illustrates the largest pattern of life's history. For millennia, the animals that populated the Earth had four toes on each foot, or six. If evolution had taken a tiny shift - if man's ancestors had inherited a couple of genes in a different form - our canonical number, based on man's fingers and toes, might be eight instead of ten. Stephen Jay Gould has also written Wonderful Life, Bully for Brontosaurus and Finders Keepers.

"Provocative and delightfully discursive essays on natural history. . . . Gould is the Stan Musial of essay writing. He can work himself into a corkscrew of ideas and improbable allusions paragraph after paragraph and then, uncoiling, hit it with such power that his fans know they are experiencing the game of essay writing at its best."--John Noble Wilford, New York Times Book Review

"Gould himself is a rare and wonderful animal—a member of the endangered species known as the ruby-throated polymath. . . . [He] is a leading theorist on large-scale patterns in evolution . . . [and] one of the sharpest and most humane thinkers in the sciences." --David Quammen, New York Times Book Review

With his customary brilliance, Gould examines the puzzles and paradoxes great and small that build nature’s and humanity’s diversity and order.

Gould covers topics as diverse as episodes in the birth of paleontology to lessons from Britain’s four greatest Victorian naturalists. This collection presents the richness and fascination of the various lives that have fueled the enterprise of science and opened our eyes to a world of unexpected wonders.

Gould’s final essay collection is based on his remarkable series for Natural History magazine—exactly 300 consecutive essays, with never a month missed, published from 1974 to 2001. Both an intellectually thrilling journey into the nature of scientific discovery and the most personal book he ever published.
