In rock art, humanlike images appear widely throughout the ages. The artworks discussed in this book range from paintings, engravings or scratchings on cave walls and rock shelters, images pecked into rocky surfaces or upon standing stones, and major sacred sites, in which exists the possibility of recovering the meanings intended by the artists.
The leading textbook in its field, this work applies paleobiological principles to the fossil record while detailing the evolutionary history of major plant and animal phyla. It incorporates current research from biology, ecology, and population genetics. Written for biology and geology undergrads, the text bridges the gap between purely theoretical paleobiology and solely descriptive invertebrate paleobiology books, emphasizing the cataloguing of live organisms over dead objects. This third edition revises art and research throughout, expands the coverage of invertebrates, includes a discussion of new methodologies, and adds a chapter on the origin and early evolution of life.
Mimicking nature - from science fiction to engineering realityHumans have always looked to nature's inventions as a source of inspiration. The observation of flying birds and insects leads to innovations in aeronautics. Collision avoidance sensors mimic the whiskers of rodents. Optimization algorithms are based on survival of the fittest, the seed-
