...Genetic Tool Kit The animals that aerated the Precambrian oceans could have resembled the wormlike something that left its meandering marks on the rock Erwin lugged back from Namibia. More advanced than a flatworm, which was not rigid enough to burrow through sand, this creature would have had a sturdy, fluid-filled body cavity. It would have had musculature capable of strong contractions. It probably had a heart, a well-defined head with an eye for sensing light and, last but not least, a gastrointestinal tract with an opening at each end. What kind of genetic machinery, Erwin wondered...
...organisms that could quickly diversify and fill all available ecological niches. Others, however, believe that in the surviving organisms, the genetic software that controls early development had become too inflexible to create new life-forms after the Permian extinction. The intricate networks of developmental genes were not so rigid as to forbid elaborate tinkering with details; otherwise, marvels like winged flight and the human brain could never have arisen. But very early on, some developmental biologists believe, the linkages between multiple genes made it difficult to change important features without lethal effect. "There must be limits to change," says Indiana...
...series, both of which augment the sheer artistic power of Giacomettian sculpture with a deep concern for the role of form and color. Despite its poorly lit display area, the genius of the bronze Detroit Queen emanates from its patinate form. Composed of sheet metal, gears, and bowls, the rigid figure in the work stands precariously balanced on the flowing forms of its "throne...
...military but endorsed gay parents as long as they create a home with love and discipline; a geology major who became, in the words of Gerald Ford and the view of many others, "the best public speaker in America"; the product of one of the most rigid, hierarchical institutions in American life who had a chance to realign political parties and reinvent race relations; a relative political unknown who inspired huge trust; a black man on a white horse...
