Synopsis
A world-renowned paleontologist reveals astonishing new science that trumps science fiction: how humans can re-create a dinosaur.
In movies, in novels, in comic strips, and on television, we've all seen dinosaurs---or at least somebody's educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on the blockbuster film Jurassic Park and a pioneer in bringing paleontology into the twenty-first century, teams up with the editor of the New York Times's Science Times section to reveal exactly what's in store.
In the 1980s, Horner began using CAT scans to look inside fossilized dinosaur eggs, and he and his colleagues have been delving deeper ever since. At North Carolina State University, Mary Schweitzer has extracted fossil molecules---proteins that survived 68 million years---from a Tyrannosaurus rex fossil excavated by Horner....
Publishers Weekly
The premise of this provocative but frustrating book by MacArthur Award-winning paleontologist Horner and New York Times deputy science editor Gorman (coauthors of Digging Dinosaurs) : a kind of reverse genetic engineering could make it possible to " build" a dinosaur embryo from the embryo of a modern bird-a chicken, say- since birds are the evolutionary descendants of dinosaurs. The trick would involve the new science of evolutionary development (known as evo devo) and a host of biological techniques. Horner and Gorman argue that during the process, one could stop and analyze every frame of the evolutionary tape as it played in reverse. The authors use the research on tail development of Hans Larsson at McGill University to explore how embryos can illuminate evolution. Much of the rest of the book offers background, but often digresses, for example, into hunting for DNA from 68-million-year-old dinosaur bones or the surfing habit of the man who discovered the polymerase chain reaction or how genetically close humans and Neanderthals are-none of which advances the book's central argument.
