Will Lightman is a Peter Pan for the 1990s. At 36, the terminally hip North Londoner is unmarried, hyper-concerned with his coolness quotient and blithely living off his father's novelty song royalties. Will sees himself as entirely lacking in hidden depths--and he's proud of it! The only trouble is, his friends are succumbing to responsibilities and children and he's increasin...(展开全部)

If the fact that they were single mothers meant that gorgeous women (who would not ordinarily look twice at Will) were willing to date him, then Will had it made. Inventing a son got him into a single parents support group, but rather than a fabulous new sex life, he found someone else's very real son -- a twelve-year-old with a lot to teach Will about being a grown up.

尼尔斯·艾崔奇（Niles Eldredge），美国最重要的演化学家之一，生物演化“点断平衡”理论之父，同时，他还是可与《自私的基因》作者道金斯比肩的演化学家和科普作家。在超过45年的时间里，艾崔奇凭借扎实的研究和精彩的著作极大地扩展了公众对生物演化的想象与认知。他至今出版过20多部科普著作，并发表过200多篇文章。2000年，由他撰写的《平衡中的生命》（Life in the Balance）被美国《出版人周刊》誉为史上最好的生物科普著作之一。 20世纪70年代，艾崔奇与好友史蒂芬·古尔德（Stephen Gould）共同开创了生物演化的“点断平衡”理论,这一理论是演化学界的里程碑，不仅对达尔文的进化论形成了重要的补充，也成为了与“自私的基因”理论并驾齐驱的流行演化学说。

"This book is a splendidly illustrated and thoughtfully constructed account of one of the greatest ideas ever conceived by the human mind -- evolution. Eldredge has cleverly combined our knowledge of living organisms with instructive insights into the fossil record to convincingly argue that evolution is, indeed, the grand unifying idea of biology." -- Donald C. Johanson, Found...(展开全部)
