ワンダフル・ライフ―バージェス頁岩と生物進化の物語 (ハヤカワ文庫NF) [文庫]

Basing his argument around the history of science's treatment of the fossils of the Burgess shale, the author presents a view of evolution as a non-progressive system, which saw a wide range of early designs for life winnowed down to the relatively few basic designs that exist today. --このテキストは、絶版本またはこのタイトルには設定されていない版型に関連付けられています。

1909年、カナダで5億年前の不思議な化石小動物群が発見された。当初、節足動物と思われたその奇妙奇天烈、妙ちくりんな生きものたちはしかし、既存の分類体系のどこにも収まらず、しかもわれわれが抱く生物進化観に全面的な見直しを迫るものだった…100点以上の珍しい図版を駆使して化石発見と解釈にまつわる緊迫のドラマを再現し、歴史の偶発性と生命の素晴らしさを謳いあげる、進化生物学の旗手グールドの代表作。

The Burgess Shale of British Columbia "is the most precious and important of all fossil localities," writes Stephen Jay Gould. These 600-million-year-old rocks preserve the soft parts of a collection of animals unlike any other. Just how unlike is the subject of Gould's book.

Gould describes how the Burgess Shale fauna was discovered, reassembled, and analyzed in detail so clear that the reader actually gets some feeling for what paleobiologists do, in the field and in the lab. The many line drawings are unusually beautiful, and now can be compared to a wonderful collection of photographs in Fossils of the Burgess Shale by Derek Briggs, one of Gould's students.

Burgess Shale animals have been called a "paleontological Rorschach test," and not every geologist by any means agrees with Gould's thesis that they represent a "road not taken" in the history of life. Simon Conway Morris, one of the subjects of Wonderful Life, has expressed his disagreement in Crucible of Creation. Wonderful Life was published in 1989, and there has been an explosion of scientific interest in the pre-Cambrian and Cambrian periods, with radical new ideas fighting for dominance. But even though many scientists disagree with Gould about the radical oddity of the Burgess Shale animals, his argument that the history of life is profoundly contingent--as in the movie It's a Wonderful Life, from which this book takes its title--has become more accepted, in theories such as Ward and Brownlee's Rare Earth hypothesis. And Gould's loving, detailed exposition of the labor it took to understand the Burgess Shale remains one of the best explanations of scientific work around. --Mary Ellen Curtin

The Burgess Shale, a small quarry in the mountains of British Columbia, opened a window on the first multicellular animals. Gould, eminent life-historian and author, introduces us to the creatures of Burgess Shale and to those who have painstakingly examined them. "This is exciting and illuminating material on the beginnings of life," wrote PW. Illustrated.

Tucked into the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. Discovered early in the century, the shale holds the remains of an ancient sea that nurtured more varities of life than can be found in all of our modern oceans.

Darwinian theory says that animals living so long ago were necessarily simple in design and limited in scope. But more recent interpretations unexpectedly reveal the great diversity locked in the shale.

Explosive stuff, for it blasts the belief that the history of life has been a broadening of options and challenges the idea that humans crown the evolutionary process.

Stephen Jay Gould advocates the role played in this process by chance. Things could easily have gone differently. It makes the reader wonder what might have been, and lets each of us provide our own answer.
