Spider Silk

Leslie Brunetta and Catherine L. Craig tell the intriguing story of how spiders evolved over 400 million years to add new silks and new uses of silk to their survival "toolkit." In the telling, they describe the trials and triumphs of spiders as they use silk to negotiate an ever-changing environment, and they show how natural selection acts at the genetic level and as individuals struggle for survival. -- Cover, p.
