Paperback. Condición: new. Paperback. The Genesis of mankind is a story that changes with the available knowledge. Here it is retold, based on recent biological facts and archaeological discoveries.We are mammals of the order of the primates. Our ancestors are apes and our closest relatives chimpanzees and bonobos. Two million years ago the species to which we belong, Homo erectus, evolved in Afrika: An upright walking carnivorous ape-man with large brains. This clever species started to conquer the world splitting frequently into subspecies that kept interbreeding until finally we, Homo erectus sapiens, remained as the only descendants.Using the large brains, it was able to evade natural selection processes and numbers kept growing to reach 8 billion individuals now.The downside of the extreme abundance becomes more and more clear. We changed the world by eliminating almost half of the large terrestrial mammalian species and use so much energy that we cause mass extinctions of entire terrestrial and aquatic ecosystems worldwide, meanwhile exceeding the carrying capacity of the earth during a period of global warming. Overpopulation is our main problem; solutions are not yet in sight. This item is printed on demand.

Paperback. Condición: New. Illustrated. Bird flight has always intrigued mankind. This book provides an up-to-date account of our existing knowledge on the subject, offering new insights and challenging some established views. A brief history of the science of flight introduces the basic physical principles governing aerial locomotion. This is followed by a treatment of flight-related functional morphology, concentrating on the difference in shape of the arm and hand part of the wings, on the structure and function of tails, and on the shape of the body. The anatomy and mechanical properties of feathers receive special attention. Aerodynamic principles used by birds are explained in theory by simply applying Newton's laws, and in practice by showing the direction and velocity of the attached flow around an arm wing cross section and of the leading edge vortex flow above a hand wing. The Archaeopteryx fossils remain crucial in our understanding of the evolution of bird flight despite the recent discovery of a range of well-preserved ancient birds. Avian Flight offers a novel insight into the interactions between wings and air which challenges established theories relating to the origin of bird flight. Take-off, flapping flight, gliding and landing are the basic ingredients of bird flight, and birds use a variety of flight styles from hovering to soaring. Flight muscles are the engines that generate the force required to keep the wings and tail in the gliding configuration and perform work during flapping motion. The energy required to fly can be estimated or measured directly, and a comparison of the empirical results provides insights into the trend in metabolic costs of flight of birds varying in shape and mass from hummingbirds to albatrosses. The book will be of interest to biologists, ornithologists, and bird watchers. It will also be of relevance and use to physicists, mathematicians, and engineers involved with aerodynamics.…
