Book Denisovan Origins

Download or read book Denisovan Origins written by Andrew Collins and published by Simon and Schuster. This book was released on 2019-09-03 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reveals the profound influence of the Denisovans and their hybrid descendants upon the flowering of human civilization around the world • Traces the migrations of the sophisticated Denisovans and their interbreeding with Neanderthals and early human populations more than 40,000 years ago • Shows how Denisovan hybrids became the elite of ancient societies, including the Adena mound-building culture • Explores the Denisovans’ extraordinary advances, including precision-machined stone tools and jewelry, tailored clothing, and celestially-aligned architecture Ice-age cave artists, the builders at Göbekli Tepe, and the mound-builders of North America all share a common ancestry in the Solutreans, Neanderthal-human hybrids of immense sophistication, who dominated southwest Europe before reaching North America 20,000 years ago. Yet, even before the Solutreans, the American continent was home to a powerful population of enormous stature, giants remembered in Native American legend as the Thunder People. New research shows they were hybrid descendants of an extinct human group known as the Denisovans, whose existence has now been confirmed from fossil remains found in a cave in the Altai region of Siberia. Tracing the migrations of the Denisovans and their interbreeding with Neanderthals and early human populations in Asia, Europe, Australia, and the Americas, Andrew Collins and Greg Little explore how the new mental capabilities of the Denisovan-Neanderthal and Denisovan-human hybrids greatly accelerated the flowering of human civilization over 40,000 years ago. They show how the Denisovans displayed sophisticated advances, including precision-machined stone tools and jewelry, tailored clothing, celestially-aligned architecture, and horse domestication. Examining evidence from ancient America, the authors reveal how Denisovan hybrids became the elite of the Adena mound-building culture, explaining the giant skeletons found in Native American burial mounds. The authors also explore how the Denisovans’ descendants were the creators of a cosmological death journey and viewed the Milky Way as the Path of Souls. Revealing the impact of the Denisovans upon every part of the world, the authors show that, without early man’s hybridization with Denisovans, Neanderthals, and other yet-to-be-discovered hominid populations, the modern world as we know it would not exist.

Book Who We Are and How We Got Here

Download or read book Who We Are and How We Got Here written by David Reich and published by Oxford University Press. This book was released on 2018-03-29 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?

Book The Origin of Our Species

Download or read book The Origin of Our Species written by Chris Stringer and published by Penguin Books. This book was released on 2012 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chris Stringer's bestselling The Origin of our Species tackles the big questions in the ongoing debate about the beginnings of human life on earth. Do all humans originate from Africa? How did we spread across the globe? Are we separate from Neanderthals, or do some of us actually have their genes? When did humans become 'modern' - are traits such as art, technology, language, ritual and belief unique to us? Has human evolution stopped, or are we still evolving? Chris Stringer has been involved in much of the crucial research into the origins of humanity, and here he draws on a wealth of evidence - from fossils and archaeology to Charles Darwin's theories and the mysteries of ancient DNA - to reveal the definitive story of where we came from, how we lived, how we got here and who we are. 'A new way of defining us and our place in history' Sunday Times 'When it comes to human evolution Chris Stringer is as close to the horse's mouth as it gets ... The Origin of Our Species should be the one-stop source on the subject. Read it now' BBC Focus 'Britain's foremost expert on human evolution ... you need a primer to make sense of the story so far. Here is that book' Guardian 'Combines anecdote and speculation with crisp explanation of the latest science in the study of the first humans ... an engaging read' New Scientist Chris Stringer is Britain's foremost expert on human origins and works in the Department of Palaeontology at the Natural History Museum. He also currently directs the Ancient Human Occupation of Britain project, aimed at reconstructing the first detailed history of how and when Britain was occupied by early humans. His previous books include African Exodus- The Origins of Modern Humanity, The Complete World of Human Evolutionand most recently, Homo Britannicus, which was shortlisted for the Royal Society Science Book of the Year in 2007.

Book The Cygnus Key

Download or read book The Cygnus Key written by Andrew Collins and published by Simon and Schuster. This book was released on 2018-05-15 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: New evidence showing that the earliest origins of human culture, religion, and technology derive from the lost world of the Denisovans • Explains how Göbekli Tepe and the Giza pyramids are aligned with the constellation of Cygnus and show evidence of enhanced sound-acoustic technology • Traces the origins of Göbekli Tepe and the Giza pyramids to the Denisovans, a previously unknown human population remembered in myth as a race of giants • Shows how the ancient belief in Cygnus as the origin point for the human soul is as much as 45,000 years old and originally came from southern Siberia Built at the end of the last ice age around 9600 BCE, Göbekli Tepe in southeast Turkey was designed to align with the constellation of the celestial swan, Cygnus--a fact confirmed by the discovery at the site of a tiny bone plaque carved with the three key stars of Cygnus. Remarkably, the three main pyramids at Giza in Egypt, including the Great Pyramid, align with the same three stars. But where did this ancient veneration of Cygnus come from? Showing that Cygnus was once seen as a portal to the sky-world, Andrew Collins reveals how, at both sites, the attention toward this star group is linked with sound acoustics and the use of musical intervals “discovered” thousands of years later by the Greek mathematician Pythagoras. Collins traces these ideas as well as early advances in human technology and cosmology back to the Altai-Baikal region of Russian Siberia, where the cult of the swan flourished as much as 20,000 years ago. He shows how these concepts, including a complex numeric system based on long-term eclipse cycles, are derived from an extinct human population known as the Denisovans. Not only were they of exceptional size--the ancient giants of myth--but archaeological discoveries show that this previously unrecognized human population achieved an advanced level of culture, including the use of high-speed drilling techniques and the creation of musical instruments. The author explains how the stars of Cygnus coincided with the turning point of the heavens at the moment the Denisovan legacy was handed to the first human societies in southern Siberia 45,000 years ago, catalyzing beliefs in swan ancestry and an understanding of Cygnus as the source of cosmic creation. It also led to powerful ideas involving the Milky Way’s Dark Rift, viewed as the Path of Souls and the sky-road shamans travel to reach the sky-world. He explores how their sound technology and ancient cosmologies were carried into the West, flowering first at Göbekli Tepe and then later in Egypt’s Nile Valley. Collins shows how the ancient belief in Cygnus as the source of creation can also be found in many other cultures around the world, further confirming the role played by the Denisovan legacy in the genesis of human civilization.

Book A Short History of Humanity

Download or read book A Short History of Humanity written by Johannes Krause and published by Random House. This book was released on 2021-04-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity has often found itself on the precipice. We've survived and thrived because we've never stopped moving... 'Stops you dead in your tracks ... An absolute revelation' Sue Black, bestselling author of All That Remains In this eye-opening book, Johannes Krause, Chair of the Max Planck Institute for the History of Humanity, offers a new way of understanding our past, present and future. Marshalling unique insights from archaeogenetics, an emerging new discipline that allows us to read our ancestors' DNA like journals chronicling personal stories of migration, Krause charts two millennia of adaption, movement and survival, culminating in the triumph of Homo Sapiens as we swept through Europe and beyond in successive waves of migration - developing everything from language, the patriarchy, disease, art and a love of pets as we did so. We also meet our ancestors, from those many of us have heard of - such as Homo Erectus and the Neanderthals - to the wildly unfamiliar but no less real: the recently discovered Denisovans, who ranged across Asia and, like humans, interbred with Neanderthals; the Aurignacians, skilled artists who, 40,000 years ago, brought about an extraordinary transformation in what our species could invent and create; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt did; and the Gravettians, big game hunters who were Europe's most successful early settlers until they perished in the face of the toughest opponent humanity had ever faced: the ice age. As well as being a radical new telling of our shared story, this book is a reminder that the global problems that keep us awake at night - climate catastrophe; the sudden emergence of deadly epidemics; refugee crises; ethnic conflict; over-population - are all things we've faced, and overcome, before.

Book Dynamics of Learning in Neanderthals and Modern Humans Volume 1

Download or read book Dynamics of Learning in Neanderthals and Modern Humans Volume 1 written by Takeru Akazawa and published by Springer Science & Business Media. This book was released on 2013-12-16 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the first of two proceedings from the International Conference on the Replacement of Neanderthals by Modern Humans, which took place in Tokyo in November 2012. Focussing on a highly innovative working hypothesis called the ‘learning hypothesis’, which attempts to explain the replacement as a result of differences in the learning abilities of these two hominid populations, the conference served as the latest multidisciplinary discussion forum on this intriguing Palaeoanthropological issue. The present volume reports on outcomes of the conference in three major sections. Part 1 provides an archaeological overview of the processes of replacement/assimilation of Neanderthals by modern humans. Part 2 consists of archaeological and ethnographic case studies exploring evidence of learning behaviours in prehistoric and modern hunter-gatherer societies. Part 3 presents a collection of papers that directly contributes to the definition, validation and testing of the learning hypothesis in terms of population biology and evolutionary theory. A total of 18 papers in this volume make available to readers unique cultural perspectives on mechanisms of the replacement/assimilation of Neanderthals by modern humans and suggested relationships between these mechanisms and different learning strategies.

Download or read book Neanderthal Man written by Svante Pääbo and published by Basic Books. This book was released on 2014-02-11 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: A preeminent geneticist, winner of the 2022 Nobel Prize in medicine, hunts the Neanderthal and Denisovan genomes to answer the biggest question of them all: how did our ancestors become human? Neanderthal Man tells the riveting personal and scientific story of the quest to use ancient DNA to unlock the secrets of human evolution. Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA, Svante Pääbo. We learn that Neanderthal genes offer a unique window into the lives of our ancient relatives and may hold the key to unlocking the mysteries of where language came from as well as why humans survived while Neanderthals went extinct. Pääbo redrew our family tree and permanently changed the way we think about who we are and how we got here. For readers of Richard Dawkins, David Reich, and Hope Jahren, Neanderthal Man is the must-read account of how he did it.

Book Gobekli Tepe  Genesis of the Gods

Download or read book Gobekli Tepe Genesis of the Gods written by Andrew Collins and published by Simon and Schuster. This book was released on 2014-05-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of the megalithic complex at Göbekli Tepe, who built it, and how it gave rise to legends regarding the foundations of civilization • Details the layout, architecture, and exquisite carvings at Göbekli Tepe • Explores how it was built as a reaction to a global cataclysm • Explains that it was the Watchers of the Book of Enoch and the Anunnaki gods of Sumerian tradition who created it • Reveals the location of the remains of the Garden of Eden in the same region Built at the end of the last ice age, the mysterious stone temple complex of Göbekli Tepe in Turkey is one of the greatest challenges to 21st century archaeology. As much as 7,000 years older than the Great Pyramid and Stonehenge, its strange buildings and rings of T-shaped monoliths--built with stones weighing from 10 to 15 tons--show a level of sophistication and artistic achievement unmatched until the rise of the great civilizations of the ancient world, Sumer, Egypt, and Babylon. Chronicling his travels to Göbekli Tepe and surrounding sites, Andrew Collins details the layout, architecture, and exquisite relief carvings of ice age animals and human forms found at this 12,000-year-old megalithic complex, now recognized as the oldest stone architecture in the world. He explores how it was built as a reaction to a global cataclysm--the Great Flood in the Bible--and explains how it served as a gateway and map to the sky-world, the place of first creation, reached via a bright star in the constellation of Cygnus. He reveals those behind its construction as the Watchers of the Book of Enoch and the Anunnaki gods of Sumerian tradition. Unveiling Göbekli Tepe’s foundational role in the rise of civilization, Collins shows how it is connected to humanity’s creation in the Garden of Eden and the secrets Adam passed to his son Seth, the founder of an angelic race called the Sethites. In his search for Adam’s legendary Cave of Treasures, the author discovers the Garden of Eden and the remains of the Tree of Life--in the same sacred region where Göbekli Tepe is being uncovered today.

Download or read book Lone Survivors written by Chris Stringer and published by Macmillan. This book was released on 2012-03-13 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: A top researcher proposes a controversial new theory of human evolution in a book “combining the thrill of a novel with a remarkable depth of perspective” (Nature). In this groundbreaking and engaging work of science, world-renowned paleoanthropologist Chris Stringer sets out a new theory of humanity’s origin, challenging both the multiregionalists (who hold that modern humans developed from ancient ancestors in different parts of the world) and his own “out of Africa” theory, which maintains that humans emerged rapidly in one small part of Africa and then spread to replace all other humans within and outside the continent. Stringer’s new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies. Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved. With photographs included, Lone Survivors will be the definitive account of who and what we were—and will change perceptions about our origins and about what it means to be human. “An essential book for anyone interested in psychology, sociology, anthropology, human evolution, or the scientific process.” —Library Journal “Highlights just how many tantalizing discoveries and analytical advances have enriched the field in recent years.” —Literary Review

Book Origins of the Gods

Download or read book Origins of the Gods written by Andrew Collins and published by Simon and Schuster. This book was released on 2022-04-19 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: • Explores how our ancestors used shamanic rituals at sacred sites to create portals for communication with nonhuman intelligences • Shares supporting evidence from the spiritual and shamanic beliefs of more than 100 Native American tribes • Shows how the earliest forms of shamanism began at sites like Qesem Cave in Israel more than 400,000 years ago From Göbekli Tepe in Turkey to the Egyptian pyramids, from the stone circles of Europe to the mound complexes of the Americas, Andrew Collins and Gregory L. Little show how, again and again, our ancestors built permanent sites of ceremonial activity where geomagnetic and gravitational anomalies have been recorded. They investigate how the earliest forms of animism and shamanism began at sites like the Denisova Cave in the Altai Mountains of Siberia and Qesem Cave in Israel more than 400,000 years ago. They explain how shamanic rituals and altered states of consciousness combine with the natural forces of the earth to create portals for contact with otherworldly realms—in other words, the gods of our ancestors were the result of an interaction between human consciousness and transdimensional intelligence. The authors show how the spiritual and shamanic beliefs of more than 100 Native American tribes align with their theory, and they reveal how some of these shamanic transdimensional portals are still active, sharing vivid examples from Skinwalker Ranch in Utah and Bempton in northern England. Ultimately, Collins and Little show how our modern disconnection from nature and lack of a fully visible night sky makes the manifestations from these ultraterrestrial intelligences seem random. If we can restore our spiritual connections, perhaps we can once again communicate with the higher dimensional beings who triggered the advancements of our earliest ancestors.

Download or read book Ancient Bones written by Madelaine Böhme and published by Greystone Books Ltd. This book was released on 2020-09-08 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Splendid and important... Scientifically rigorous and written with a clarity and candor that create a gripping tale... [Böhme's] account of the history of Europe's lost apes is imbued with the sweat, grime, and triumph that is the lot of the fieldworker, and carries great authority." —Tim Flannery, The New York Review of Books In this "fascinating forensic inquiry into human origins" (Kirkus STARRED Review), a renowned paleontologist takes readers behind-the-scenes of one of the most groundbreaking archaeological digs in recent history. Somewhere west of Munich, paleontologist Madelaine Böhme and her colleagues dig for clues to the origins of humankind. What they discover is beyond anything they ever imagined: the twelve-million-year-old bones of Danuvius guggenmosi make headlines around the world. This ancient ape defies prevailing theories of human history—his skeletal adaptations suggest a new common ancestor between apes and humans, one that dwelled in Europe, not Africa. Might the great apes that traveled from Africa to Europe before Danuvius's time be the key to understanding our own origins? All this and more is explored in Ancient Bones. Using her expertise as a paleoclimatologist and paleontologist, Böhme pieces together an awe-inspiring picture of great apes that crossed land bridges from Africa to Europe millions of years ago, evolving in response to the challenging conditions they found. She also takes us behind the scenes of her research, introducing us to former theories of human evolution (complete with helpful maps and diagrams), and walks us through musty museum overflow storage where she finds forgotten fossils with yellowed labels, before taking us along to the momentous dig where she and the team unearthed Danuvius guggenmosi himself—and the incredible reverberations his discovery caused around the world. Praise for Ancient Bones: "Readable and thought-provoking. Madelaine Böhme is an iconoclast whose fossil discoveries have challenged long-standing ideas on the origins of the ancestors of apes and humans." —Steve Brusatte, New York Times-bestselling author of The Rise and Fall of the Dinosaurs "An inherently fascinating, impressively informative, and exceptionally thought-provoking read." —Midwest Book Review "An impressive introduction to the burgeoning recalibration of paleoanthropology." —Kirkus Reviews (starred review)

Book excerpt: Around 60,000 years ago, a man—genetically identical to us—lived in Africa. Every person alive today is descended from him. How did this real-life Adam wind up as the father of us all? What happened to the descendants of other men who lived at the same time? And why, if modern humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races? Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour through the history and development of early humankind.
