Since its inception in 1915, the Best American series has become the premier annual showcase for the country's finest short fiction and nonfiction. For each volume, a series editor reads pieces from hundreds of periodicals, then selects between fifty and a hundred outstanding works. That selection is pared down to the twenty or so very best pieces by a guest editor who is widely recognized as a leading writer in his or her field. This unique system has helped make the Best American series the most respected -- and most popular -- of its kind. The Best American Science and Nature Writing 2004, edited by Steven Pinker, is another "provocative and thoroughly enjoyable [collection] from start to finish" (Publishers Weekly). Here is the best and newest on science and nature: the psychology of suicide terrorism, desperate measures in surgery, the weird world of octopuses, Sex Week at Yale, the linguistics of click languages, the worst news about cloning, and much more.

The Jordan Rift Valley, stretching from the Red Sea to Lebanon, was ripped open millions of years ago by vast forces within the earth. This geological object has also been a part of human history ever since early humans used it as a path in their journey out of Africa. And for a quarter of a century it has been part of the biography of Israeli writer Haim Watzman. In the autumn of 2004, as his country was riven by a fierce debate over its borders, Watzman took a two-week journey up the valley. Along the way he met scientists who try to understand the rift through the evidence lying on its surface--an archaeologist who reconstructs the fallen altars of a long-forgotten people, a zoologist whose study of bird societies has produced a theory of why organisms cooperate, and a geologist who thinks that the valley will some day be an ocean. He encountered people whose life and work on the shores of the Dead Sea and Jordan River have led them to dream of paradise and to seem to build Gardens of Eden on earth--a booster for a chemical factory, the director of a tourist site, and an aging socialist farmer who curates a museum of idols. And he discovered that the geography’s instability is mirrored in the volatility of the tales that people tell about the Sea of Galilee. As an observant Jew who has written extensively about science and scholarship, Watzman tries to understand the valley in all its complexity--its physical facts, its role in human history and his own life, and the myths it has engendered. He realizes that human beings can never see the rift in isolation. "It is the stories that men and women have told to explain what they see and what they do as a result that create the rift as we see it,” he writes. "As hard as we try to comprehend the landscape itself, it is humanity that we find. Watzman’s poetic evocation of the scientific and the human is a unique chronicle of a quest for knowledge.
