It is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution. Capacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of 'reverse evolution' by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.

This volume describes and explores the emerging discipline of conservation paleobiology, and addresses challenges faced by established and young Conservation Paleobiologist's alike. In addition, this volume includes applied research highlighting how conservation paleobiology can be used to understand ecosystem response to perturbation in near and deep time. Across 10 chapters, the book aims to (1) explore the goals of conservation paleoecology as a science, (2) highlight how conservation paleoecology can be used to understand ecosystems' responses to crises, (3) provide case studies of applications to modern ecosystems, (4) develop novel applications of paleontological approaches to neontological data, and (5) present a range of ecosystem response and recovery through environmental crises, from high-resolution impacts on organism interactions to the broadest scale of responses of the entire marine biosphere to global change. The volume will be of interest to paleoecologists, paleobiologists, and conservation biologists.

This thesis encompasses a study of past precipitation patterns based on six cave stalagmites from different parts of the Indian Himalaya. This is the first speleothem study in the Indian Himalaya that shows a direct relationship between past precipitation and the collapse of civilization. The stalagmites examined were KL-3 from Jammu and Kashmir; TCS and BR-1 from Himachal Pradesh; and DH-1, SA-1 and CH-1 from Uttarakhand. Based on the high-resolution palaeoclimatic reconstruction (35 U/th dates, 5 AMS dates, 1,500 samples for 18O and 13C values) obtained for the duration of the Pleistocene-Holocene transition (16.2-9.5 ka BP) and Mid-Holocene-Present (ca. 4.0 ka BP-Present), three major events were identified, namely the Older Dryas (OD), Bolling-Allerod (BA) period and Younger Dryas (YD) at ca. 14.3-13.9, 13.9-12.7 and 12.7-12.2 ka BP, respectively. The study showed a gradual reduction in the precipitation from 4 ka BP onwards for about a millennium with a peak arid period between 3.2 and 3.1 ka BP. According to the findings, the LIA (Little Ice Age) covers a time span from 1622-1820 AD, during which the climate was wetter than that in the post-LIA period (1820-1950 AD). In addition, this thesis supports the assumption that the WDs (Western Disturbances) contribute significantly to the total rainfall in the Himalaya region.

This edited book discusses various challenges in teaching structural geology and tectonics and how they have been overcome by eminent instructors, who employed effective and innovative means to do so. All of the chapters were written by prominent and active academics and geoscientists fully engaged in teaching Structural Geology and Tectonics. New instructors will find this book indispensible in framing their teaching strategy. Effective teaching of Structural Geology and Tectonics constitutes the backbone of geoscience education. Teaching takes place not only in classrooms, but also in labs and in the field. The content and teaching methodologies for these two fields have changed over time, shaped by the responsibilities that present-day geoscientists are expected to fulfill.

This volume addresses major evolutionary changes that took place during the Ediacaran and the Paleozoic. These include discussions on the nature of Ediacaran ecosystems, as well as the ichnologic signature of evolutionary radiations, such as the Cambrian explosion and the Great Ordovician biodiversification event, the invasion of the land, and the end-Permian mass extinction. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.

This volume addresses major evolutionary changes that took place during the Mesozoic and the Cenozoic. These include discussions on major evolutionary radiations and ecological innovations on land and at sea, such as the Mesozoic marine revolution, the Mesozoic radiation of vertebrates, the Mesozoic lacustrine revolution, the Cenozoic radiation of mammals, the evolution of paleosol biotas, and the evolution of hominins. The roles of mass extinctions at the end of the Triassic and at the end of the Cretaceous are assessed.

This book highlights Indian scientific endeavours and contributions to answering the vast multitude of questions posed by our changing environment. The International Ocean Discovery Program (IODP) explores Earth's history and dynamics using deep ocean drilling platforms to recover the data locked inside seafloor sediments and rocks. Since 2009, Indian scientists have been actively engaged in these expeditions. Scientists from various Earth Science disciplines have seized this opportunity to offer their expertise in order to help unravel the mysteries of the past - by delving deep into the valuable sedimentary records of our oceans. This book presents a compilation of some of their most important findings to motivate and encourage young minds for their enhanced role in the cutting edge science of ocean drilling.

This book aims at providing a brief but broad overview of biosignatures. The topics addressed range from prebiotic signatures in extraterrestrial materials to the signatures characterising extant life as well as fossilised life, biosignatures related to space, and space flight instrumentation to detect biosignatures either in situ or from orbit. The book ends with philosophical reflections on the implications of life elsewhere. In the 15 chapters written by an interdisciplinary team of experts, it provides both detailed explanations on the nature of biosignatures as well as useful case studies showing how they are used and identified in ancient rocks, for example. One case study addresses the controversial finding of traces of fossil life in a meteorite from Mars. The book will be of interest not only to astrobiologists but also to terrestrial paleontologists as well as any reader interested in the prospects of finding a second example of life on another planet.

It's hard to imagine the study of human origins without the Leakey family. Three generations of Leakeys have scratched in the baked, unfriendly soil of East Africa to unearth fossil evidence of the earliest humans and their ancient ancestors. In the process they have practically defined the field of paleoanthropology, while eliciting admiration as well as controversies and criticism. In this engrossing biography, prolific writer and educator Mary Bowman-Kruhm tells the story of three generations of Leakeys. Beginning with patriarch Louis Leakey, a native of Kenya, she describes how he turned his boyhood love of exploring the Kenyan countryside into a scientific profession that eventually garnered international recognition. As the author shows, Leakey struggled in the early years, often barely able to make a living. The end of World War II, a trip to Rusinga Island in Lake Victoria, and an injection of money from a benefactor led to the discovery of Proconsul africanus, an 18-million-year-old skull that was a precursor to both later evolving apes and humans. Then Leakey and his wife, Mary, discovered fragments of what came to be known as Paranthropus boisei, which lived about 1.75 million years ago. These findings brought the Leakeys great attention and important funding from the National Geographic Society.
Bowman-Kruhm intersperses her discussion of the Leakeys' important scientific contributions with interesting asides about their personal life: from the trying 1950s when the Mau Mau revolt in Kenya threatened all of their lives; through Louis's interest in young proteges, including Jane Goodall and Diane Fossey; to the rocky relationship between the Leakeys and Donald Johanson, the discoverer of "Lucy."
By the time of Louis's death in 1972, Mary and their son Richard were making dramatic finds on their own. When Richard discovered a rich cache of fossils in northern Kenya, he soon attained a level of acclaim to rival his father and mother's. Eventually, he turned his attention to fighting for the cause of wildlife conservation, a passion that he continues to the present. Today, the paleontology work of the Leakey family continues, carried on mainly by Meave, Richard's wife, and their daughter, Louise, at Koobi Fora in northern Kenya. They regularly report the results of their research at the Koobi Fora Research Project Web site (www.kfrp.com).

Alice Gerard has crossed the Atlantic a dozen times in the last ten years in her efforts to help solve the mystery of the controversial French site of Glozel, which has been called the "Dreyfus Affair" of archaeology. Accusations of fraud made by members of the archaeological establishment have contributed to the stormy history of the site during the last 80 years."Glozel" describes the exhaustive attempts Alice and her husband have made, working with other researchers, to understand the tombs, the tablets covered with unknown writing, the bones engraved with reindeer, and the phallic idols found at the site. In the process the Gerards made and lost good friends, became informed about a number of esoteric subjects, and finally developed a theory that might explain Glozel. The story is not finished; they hope the site will be recognized as authentic while Emile Fradin, who discovered the first artifacts in 1924, is still alive.

'Steve Brusatte, the author of The Rise and Fall of the Dinosaurs, brings mammals out from the shadow of their more showy predecessors in a beautifully written book that . . . makes the case for them as creatures who are just as engaging as dinosaurs.' - The Sunday Times, 'Best Books For Summer' 'In this terrific new book, Steve Brusatte . . . brings well-known extinct species, the sabre-toothed tigers and the woolly mammoths, thrillingly back to life' - The Times The passing of the age of the dinosaurs allowed mammals to become ascendant. But mammals have a much deeper history. They - or, more precisely, we - originated around the same time as the dinosaurs, over 200 million years ago; mammal roots lie even further back, some 325 million years. Over these immense stretches of geological time, mammals developed their trademark features: hair, keen senses of smell and hearing, big brains and sharp intelligence, fast growth and warm-blooded metabolism, a distinctive line-up of teeth (canines, incisors, premolars, molars), mammary glands that mothers use to nourish their babies with milk, qualities that have underlain their success story. Out of this long and rich evolutionary history came the mammals of today, including our own species and our closest cousins. But today's 6,000 mammal species - the egg-laying monotremes including the platypus, marsupials such as kangaroos and koalas that raise their tiny babies in pouches, and placentals like us, who give birth to well-developed young - are simply the few survivors of a once verdant family tree, which has been pruned both by time and mass extinctions. In The Rise and Reign of the Mammals, palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and ground-breaking book, Steve Brusatte tells their - and our - story.
