    An accomplished biologist, Sheldrake proposes that all natural systems, from crystals to human society, inherit a collective memory that influences their form and behavior. Rather than being ruled by fixed laws, nature is essentially habitual. The Presence of the Past lays out the evidence for Sheldrake's controversial theory, exploring its implications in the fields of biology, physics, psychology, and sociology. At the same time, Sheldrake delivers a stinging critique of conventional scientific thinking. In place of the mechanistic, neo-Darwinian worldview he offers a new understanding of life, matter, and mind.

    Prepared under the aegis of the Association of Space Explorers and in cooperation with the Soviet agency Mir, The Home Planet conveys as no book ever has the human dimension of space exploration, and the deeply personal response to our terrestrial home which space travel awakens.

    

    Filled with new information from the forefront of paleontology and hundreds of evocative, precisely detailed drawings, Predatory Dinosaurs of the World is the first dinosaur book for every kind of reader. Gregory S. Paul provides an extensive species-by-species catalog of all the predatory dinosaurs known to have existed, from the weasel-sized Lagosuchus to the gigantic Tyranosaurus rex. Dispelling old myths, Paul reveals the surprising capacities of the dinosaurs, including their quickness, adaptability, and agility. And he shows the enormous power of these amazing beasts, bringing them to life once more as they hunt, roam, and pillage through their strange prehistoric worlds from tropical deserts to the polar snows.Predatory Dinosaurs of the World explains how the animals lived and how they interacted with each other and the life around them. Paul details the awesome hit-and-run hunting techniques of the dinosaurs. He explains the varying features of their anatomies and physiologies and compares the ways in which different species evolved through time. He also provides skeletal restorations for many species and thousands of little-known facts. Here is an engrossing exploration of the lost kingdom of the predatory dinosaurs. Rarely has science been so lively, so entertaining--or so much fun.
