A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    Elsewhere, a team of scientists transverses the tundra, sleeping in tents, surviving on frozen chocolate, and measuring the snow every ten kilometers in a quest to understand the effects of albedo, the snow's reflective ability to cool the earth beneath it.Climate change isn't an abstraction in the far North. It is a reality that has already dramatically altered daily life, especially that of the native peoples who still live largely off the land and sea. Because nature shows her footprints so plainly here, the region is also a lure for scientists intent on comprehending the complexities of climate change. In this gripping account, Charles Wohlforth follows the two groups as they navigate a radically shifting landscape. The scientists attempt to decipher its smallest elements and to derive from them a set of abstract laws and models. The natives draw on uncannily accurate traditional knowledge, borne of long experience living close to the land. Even as they see the same things-a Native elder watches weather coming through too fast to predict; a climatologist notes an increased frequency of cyclonic systems-the two cultures struggle to reconcile their vastly different ways of comprehending the environment.With grace, clarity, and a sense of adventure, Wohlforth--a lifelong Alaskan--illuminates both ways of seeing a world in flux, and in the process, helps us to navigate a way forward as climate change reaches us all.

    The book features raw, blunt, and in your face poems depicting the darker side of relationships. Readers will find themes such as lies, cheating, and heartache abundant in much of this collection. Midnight Milkshakes, being the second volume of Ray's Ice Cream And Suicide, is great for returning readers to the series. The book focuses on much of the same style and mood that is common in his writings.

    Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process.Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

    The species that survive will be the ones that are most compatible with us: the weedy species--from mosquitoes to coyotes--that thrive in continually disturbed human-dominated environments. The End of the Wild is a wake-up call. Marshaling evidence from the last ten years of research on the environment, Stephen Meyer argues that nothing--not national or international laws, global bioreserves, local sustainability schemes, or wildlands--will change the course that has been set. Like it or not, we can no longer talk about conserving nature, only managing what is left. The race to save biodiversity is over.But that doesn't mean our work is over. The End of the Wild is also a call to action. Without intervention, the surviving ecosystems we depend on for a range of services--including water purification and flood and storm damage contro--could fail and the global spread of invasive species (pests, parasites, and disease-causing weedy species) could explode. If humanity is to survive, Meyer argues, we have no choice but to try to manage the fine details. We must move away from the current haphazard strategy of protecting species in isolation and create trans-regional meta-reserves, designed to protect ecosystem functions rather than species-specific habitats.

    It is written in an easy-to-remember way which links the theory back to your practical driving experience to help you really understand.

    We meet Eskimos whose way of life is melting away, explore a secret global seed vault hidden above the Arctic Circle, investigate dilemmas facing foraging bears and breeding penguins, and sail to formerly devastated reefs that are resurrecting as fish graze the corals algae-free."Each time science tightens a coil in the slack of our understanding," Safina writes, "it elaborates its fundamental discovery: connection."He shows how problems of the environment drive very real matters of human justice, well-being, and our prospects for peace.In Safina's hands, nature's continuous renewal points toward our future. His lively stories grant new insights into how our world is changing, and what our response ought to be.

    Few people, however, know that research into tree rings has also made amazing contributions to our understanding of Earth's climate history and its influences on human civilization over the past 2,000 years. In her captivating new book, Tree Story, Valerie Trouet reveals how the seemingly simple and relatively familiar concept of counting tree rings has inspired far-reaching scientific breakthroughs that illuminate the complex interactions between nature and people.Trouet, a leading tree-ring scientist, takes us out into the field, from remote African villages to radioactive Russian forests, offering readers an insider's look at tree-ring research, a discipline formally known as dendrochronology. Tracing her own professional journey while exploring dendrochronology's history and applications, Trouet describes the basics of how tell-tale tree cores are collected and dated with ring-by-ring precision, explaining the unexpected and momentous insights we've gained from the resulting samples.Blending popular science, travelogue, and cultural history, Tree Story highlights exciting findings of tree-ring research, including the fate of lost pirate treasure, successful strategies for surviving California wildfire, the secret to Genghis Khan's victories, the connection between Egyptian pharaohs and volcanoes, and even the role of olives in the fall of Rome. These fascinating tales are deftly woven together to show us how dendrochronology sheds light on global climate dynamics and uncovers the clear links between humans and our leafy neighbors. Trouet delights us with her dedication to the tangible appeal of studying trees, a discipline that has taken her to austere and beautiful landscapes around the globe and has enabled scientists to solve long-pondered mysteries of Earth and its human inhabitants.

    Now, with an astonishing new discovery, everything we thought we knew about primate origins could change. Lying inside a high-security vault, deep within the heart of one of the world's leading natural history museums, is the scientific find of a lifetime - a perfectly fossilized early primate, older than the previously most famous primate fossil, Lucy, by forty-four million years.  A secret until now, the fossil - "Ida" to the researchers who have painstakingly verified her provenance - is the most complete primate fossil ever found. Forty-seven million years old, Ida rewrites what we've assumed about the earliest primate origins. Her completeness is unparalleled - so much of what we understand about evolution comes from partial fossils and even single bones, but Ida's fossilization offers much more than that, from a haunting "skin shadow" to her stomach contents. And, remarkably, knowledge of her discovery and existence almost never saw the light of day. With exclusive access to the first scientists to study her, the award-winning science writer Colin Tudge tells the history of Ida and her place in the world. A magnificent, cutting-edge scientific detective story followed her discovery, and The Link offers a wide-ranging investigation into Ida and our earliest origins. At the same time, it opens a stunningly evocative window into our past and changes what we know about primate evolution and, ultimately, our own.

    The book argues for a realization of the finite nature of our resources, and the impact should we continue squandering them.

    

    Lavishly illustrated with over sixty original artworks, All Yesterdays aims to challenge our notions of how prehistoric animals looked and behaved.
