Were dinosaurs really dumber than lizards? Why, after all, are roughly the same number of men and women born into the world? What led the famous Dr. Down to his theory of mongolism, and its racist residue? What do the panda's magical "thumb" and the sea turtle's perilous migration tell us about imperfections that prove the evolutionary rule? The wonders and mysteries of evolutionary biology are elegantly explored in these and other essays by the celebrated natural history writer Stephen Jay Gould.

Over a century after Darwin published the Origin of Species, Darwinian theory is in a "vibrantly healthy state," writes Stephen Jay Gould, its most engaging and illuminating exponent. Exploring the "peculiar and mysterious particulars of nature," Gould introduces the listener to some of the many and wonderful manifestations of evolutionary biology.

Among scientists who write, no one illuminates as well as Stephen Jay Gould does the 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 ancestral generations. 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.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

In this fascinating history of the age-old battle between Science and Religion, evolutionist Stephen Jay Gould argues that part of living the full human experience is achieving a balance between the spiritual and the rational."
