    As well as exploring how birds achieve the miracle of flight; why birds sing; what they tell us about the seasons of the year and what their presence tells us about the places they inhabit, The Meaning of Birds muses on the uses of feathers, the drama of raptors, the slaughter of pheasants, the infidelities of geese, and the strangeness of feeling sentimental about blue tits while enjoying a chicken sandwich.From the mocking-birds of the Galapagos who guided Charles Darwin toward his evolutionary theory, to the changing patterns of migration that alert us to the reality of contemporary climate change, Simon Barnes explores both the intrinsic wonder of what it is to be a bird—and the myriad ways in which birds can help us understand the meaning of life.

    This Penguin Classics edition is edited with an introduction by James Moore and Adrian Desmond.In The Origin of Species, Charles Darwin refused to discuss human evolution, believing the subject too 'surrounded with prejudices'. He had been reworking his notes since the 1830s, but only with trepidation did he finally publish The Descent of Man in 1871. The book notoriously put apes in our family tree and made the races one family, diversified by 'sexual selection' - Darwin's provocative theory that female choice among competing males leads to diverging racial characteristics. Named by Sigmund Freud as 'one of the ten most significant books' ever written, Darwin's Descent of Man continues to shape the way we think about what it is that makes us uniquely human.In their introduction, James Moore and Adrian Desmond, acclaimed biographers of Charles Darwin, call for a radical re-assessment of the book, arguing that its core ideas on race were fired by Darwin's hatred of slavery. The text is the second and definitive edition and this volume also contains suggestions for further reading, a chronology and biographical sketches of prominent individuals mentioned.Charles Darwin (1809-82), a Victorian scientist and naturalist, has become one of the most famous figures of science to date. The advent of On the Origin of Species by Means of Natural Selection in 1859 challenged and contradicted all contemporary biological and religious beliefs.If you enjoyed The Descent of Man, you might like Darwin's On the Origin of Species, also available in Penguin Classics.

    They unearthed a treasure trove of Cretaceous dinosaurs and mammals, including several new species, that has already helped to reshape our understanding of the dinosaur age. In Dinosaurs of the Flaming Cliffs, team leader Michael Novacek, Provost of Science of the American Museum of Natural History and Curator of Vertebrate Paleontology, re-creates the day-to-day drama of field exploration over the past six years in the Gobi and recounts his and his colleagues' historic discoveries, reported in front-page headlines across the world. In a remarkable narrative that interweaves expedition chapters with in-depth scientific discussions on the nature and importance of the fossil record, Novacek takes us on a journey that explores the very nature of scientific inquiry and dinosaur research.

    The book features case discussions, USMLE-style questions, and a USMLE-style practice exam.

    You may think you know your cat as he purrs in your lap, but come across your pet in the street on a dark night and you might think that Bagpuss suffers from a dual personality.Every single feline pet carries an inheritance of amazing sensory capacities, vocal utterances, body language and territorial displays. By answering such questions as 'what does a cat signal with its ears? 'why does a cat rub up against your leg?' and 'why does a cat swing its head from side to side when staring at its prey?', Desmond Morris decodes the private world of the cat.Your cat is full of surprises and our finest zoologist is about to reveal their secrets in this beautifully repackaged edition of a much loved bestseller.

    Presenting details about the parts of the skull (including the cranium, the mandible, the shape and positioning of the eye sockets, and species-specific features like horns, teeth, beaks and bills), information about the science and pseudoscience of skulls, and a look at skulls in religion, art and popular culture, his stories and information are riveting and enlightening.At the center of "Skulls" is a stunning, never-before-seen-in-any-capacity, visual array of the skulls of more than 300 animals that walk, swim, and fly.

And yet we’re in an age of rapid discovery—new dinosaur species and genera are being discovered at an accelerating rate, we’re learning more about what they looked like, how they lived, how they evolved and where they all went.This series isn’t just a top trumps list of dino facts—we’re interested in the why and the how and like all areas of science there is plenty of controversy and debate.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.
