New Evidence for Two Human Origins by Gary T. Mayer Pdf
The subject of human origins is a topic that not only feeds our curiosity; it also offers to be a topic that can bring us greater meaning to our lives. It has been assumed by many scientists and biblical scholars that the human race emerged from a single nucleus. Could this have been a wrong assumption? New evidence has come to light indicating that Adam and Eves descendants married into an existing race. Where did this existing race come from? When and where did these two races merge? This book provides a thesis which answers all these questions and, in so doing, harmonizes the teaching of the Bible and the true teachings of science.
In 1856 - as Darwin was completing Origin of Species - the fossilized remains of a stocky, powerful human-like creature were discovered in a cave in the Neander Valley in Germany. This work offers an account of the search for man's beginnings and out of a particular man - dead for 40, 000 years - who began a revolution that changed the world.

In the Light of Evolution by National Academy of Sciences Pdf
The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

Java Man by Carl C. Swisher III,Carl Celso Swisher,Garniss H. Curtis,Roger Lewin Pdf
"'Garniss, lend me your knife for a second, will you,' I whispered." So begins Java Man, the inside story of how one discovery—a human skull found on the island of Java—by two geologists shook the foundations of science. By uncovering new evidence about the hominid known as Java man, Carl C. Swisher and Garniss H. Curtis were able to date his fossil remains at 1.7 million years, an age that stunned the scientific community because it pushed back the time when humans migrating out of Africa first reached Eurasia by nearly one million years. Cowritten by the popular science writer Roger Lewin, this is a gripping and informative account of the discovery that breathed new life into the human origins debate.

Understanding Climate's Influence on Human Evolution by National Research Council,Division on Earth and Life Studies,Board on Earth Sciences and Resources,Committee on the Earth System Context for Hominin Evolution Pdf
The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it means to be human, including the origins of bipedalism; the emergence of our genus Homo; the first use of stone tools; increases in brain size; and the emergence of Homo sapiens, tools, and culture. The Earth's geological record suggests that some evolutionary events were coincident with substantial changes in African and Eurasian climate, raising the possibility that critical junctures in human evolution and behavioral development may have been affected by the environmental characteristics of the areas where hominins evolved. Understanding Climate's Change on Human Evolution explores the opportunities of using scientific research to improve our understanding of how climate may have helped shape our species. Improved climate records for specific regions will be required before it is possible to evaluate how critical resources for hominins, especially water and vegetation, would have been distributed on the landscape during key intervals of hominin history. Existing records contain substantial temporal gaps. The book's initiatives are presented in two major research themes: first, determining the impacts of climate change and climate variability on human evolution and dispersal; and second, integrating climate modeling, environmental records, and biotic responses. Understanding Climate's Change on Human Evolution suggests a new scientific program for international climate and human evolution studies that involve an exploration initiative to locate new fossil sites and to broaden the geographic and temporal sampling of the fossil and archeological record; a comprehensive and integrative scientific drilling program in lakes, lake bed outcrops, and ocean basins surrounding the regions where hominins evolved and a major investment in climate modeling experiments for key time intervals and regions that are critical to understanding human evolution.
What Does it Mean to be Human? by Richard Potts,Christopher Sloan Pdf
This generously illustrated book tells the story of the human family, showing how our species' physical traits and behaviors evolved over millions of years as our ancestors adapted to dramatic environmental changes. In What Does It Means to Be Human? Rick Potts, director of the Smithsonian's Human Origins Program, and Chris Sloan, National Geographic's paleoanthropolgy expert, delve into our distant past to explain when, why, and how we acquired the unique biological and cultural qualities that govern our most fundamental connections and interactions with other people and with the natural world. Drawing on the latest research, they conclude that we are the last survivors of a once-diverse family tree, and that our evolution was shaped by one of the most unstable eras in Earth's environmental history. The book presents a wealth of attractive new material especially developed for the Hall's displays, from life-like reconstructions of our ancestors sculpted by the acclaimed John Gurche to photographs from National Geographic and Smithsonian archives, along with informative graphics and illustrations. In coordination with the exhibit opening, the PBS program NOVA will present a related three-part television series, and the museum will launch a website expected to draw 40 million visitors.
The Descent of Man, and Selection in Relation to Sex by Charles Darwin Pdf
In the current resurgence of interest in the biological basis of animal behavior and social organization, the ideas and questions pursued by Charles Darwin remain fresh and insightful. This is especially true of The Descent of Man and Selection in Relation to Sex, Darwin's second most important work. This edition is a facsimile reprint of the first printing of the first edition (1871), not previously available in paperback. The work is divided into two parts. Part One marshals behavioral and morphological evidence to argue that humans evolved from other animals. Darwin shoes that human mental and emotional capacities, far from making human beings unique, are evidence of an animal origin and evolutionary development. Part Two is an extended discussion of the differences between the sexes of many species and how they arose as a result of selection. Here Darwin lays the foundation for much contemporary research by arguing that many characteristics of animals have evolved not in response to the selective pressures exerted by their physical and biological environment, but rather to confer an advantage in sexual competition. These two themes are drawn together in two final chapters on the role of sexual selection in humans. In their Introduction, Professors Bonner and May discuss the place of The Descent in its own time and relation to current work in biology and other disciplines.
Bones, Stones and Molecules by David W. Cameron,Colin P. Groves Pdf
Bones, Stones and Molecules provides some of the best evidence for resolving the debate between the two hypotheses of human origins. The debate between the 'Out of Africa' model and the 'Multiregional' hypothesis is examined through the functional and developmental processes associated with the evolution of the human skull and face and focuses on the significance of the Australian record. The book analyzes important new discoveries that have occurred recently and examines evidence that is not available elsewhere. Cameron and Groves argue that the existing evidence supports a recent origin for modern humans from Africa. They also specifically relate these two theories to interpretations of the origins of the first Australians. The book provides an up-to-date interpretation of the fossil, archaeological and the molecular evidence, specifically as it relates to Asia, and Australia in particular. Readily accessible to the layperson and professional Provides concise coverage of current scientific evidence Presents a robust computer-generated model of human speciation over the last 7 million years Well illustrated with figures and photographs of important fossil specimens Presents a synthesis of great ape and human evolution
Richard Leakey's personal account of his fossil hunting and landmark discoveries at Lake Turkana, his reassessment of human prehistory based on new evidence and analytic techniques, and his profound pondering of how we became "human" and what being "human" really means.

The Indigenous Paleolithic of the Western Hemisphere by Paulette F. C. Steeves Pdf
2022 Choice Outstanding Academic Title The Indigenous Paleolithic of the Western Hemisphere is a reclaimed history of the deep past of Indigenous people in North and South America during the Paleolithic. Paulette F. C. Steeves mines evidence from archaeology sites and Paleolithic environments, landscapes, and mammalian and human migrations to make the case that people have been in the Western Hemisphere not only just prior to Clovis sites (10,200 years ago) but for more than 60,000 years, and likely more than 100,000 years. Steeves discusses the political history of American anthropology to focus on why pre-Clovis sites have been dismissed by the field for nearly a century. She explores supporting evidence from genetics and linguistic anthropology regarding First Peoples and time frames of early migrations. Additionally, she highlights the work and struggles faced by a small yet vibrant group of American and European archaeologists who have excavated and reported on numerous pre-Clovis archaeology sites. In this first book on Paleolithic archaeology of the Americas written from an Indigenous perspective, The Indigenous Paleolithic of the Western Hemisphere includes Indigenous oral traditions, archaeological evidence, and a critical and decolonizing discussion of the development of archaeology in the Americas.
A Story of Us by Lesley Newson,Peter Richerson Pdf
It's time for a story of human evolution that goes beyond describing "ape-men" and talks about what women and children were doing. In a few decades, a torrent of new evidence and ideas about human evolution has allowed scientists to piece together a more detailed understanding of what went on thousands and even millions of years ago. We now know much more about the problems our ancestors faced, the solutions they found, and the trade-offs they made. The drama of their experiences led to the humans we are today: an animal that relies on a complex culture. We are a species that can and does rapidly evolve cultural solutions as we face new problems, but the intricacies of our cultures mean that this often creates new challenges. Our species' unique capacity for culture began to evolve millions of years ago, but it only really took off in the last few hundred thousand years. This capacity allowed our ancestors to survive and raise their difficult children during times of extreme climate chaos. Understanding how this has evolved can help us understand the cultural change and diversity that we experience today. Lesley Newson and Peter Richerson, a husband-and-wife team based at the University of California, Davis, began their careers with training in biology. The two have spent years together and individually researching and collaborating with scholars from a wide range of disciplines to produce a deep history of humankind. In A Story of Us, they present this rich narrative and explain how the evolution of our genes relates to the evolution of our cultures. Newson and Richerson take readers through seven stages of human evolution, beginning seven million years ago with the apes that were the ancestors of humans and today's chimps and bonobos. The story ends in the present day and offers a glimpse into the future.
Race And Human Evolution by Milford Wolpoff,Rachel Caspari Pdf
Where do humans come from? How did they evolve? How did different races come into existence? The quest for modern human origins has both fascinated and divided people for centuries. Theories of race and questions of whether humans can be categorized in different species have caused polarization and discord in the sciences throughout history, and theories currently in vogue may have as much to do with contemporary cultural politics as with science. Race and Human Evolution is a far-ranging account by leading researchers in the field that describes the latest scientific evidence and the conflicting theories about human evolution. Milford Wolpoff and Rachel Caspari describe the “Eve” or “Out-of-Africa” theory, which holds that all living people are the descendants of a single common ancestor (“Eve”) who began a new species of humanity in Africa some 200,000 years ago and whose progeny spread throughout the world, giving rise to the different human races. The authors show that the evidence of the fossil record and genetic data support “Multiregionalism,” which posits that for some two million years human populations have been entwined in a network of widespread peoples who evolved together because they met and interbred, giving the races today many ancestors, not a single common one. Race and Human Evolution shows how the debate over the “Eve” theory reflects a long history of theories about human origins and race that has been fraught with social and political implications. Race and human evolution have become tangled during some of the most important eras in our history: European colonizations, which sparked questions over the humanity of indigenous natives, and the slavery issue and whether Jefferson's claims of humanity and quality for all people applied to slaves. While Darwinism, the discovery of Neanderthals, and Mendel's genetic theories combined to give us modern paleoanthropology, the eugenics movement and even Nazism also sprang from these ideas.The debate now raging cannot free itself of this background. Certain to be controversial but also to illuminate an argument that has persisted for centuries and which persists in some of today's most inflammatory social and political issues, Race and Human Evolution provides an authoritative account of the science and the scientists behind the controversy over the origin of humanity and its racial differences.
70,000 years ago, two new haplogroups appeared in East Africa, the L3 mtDNA lineage and the CT Y-chromosomal lineage. Almost all non-Africans can trace their maternal and paternal ancestry from these two lines. This understanding establishes the earliest possible dating for an African migration event populating Eurasia and America.Archaeological evidence places modern humans in Australasia earlier than 70,000 years ago. Genetic research confirms that Australasian Aboriginal populations are descended from the HgL3 and HgCT lineages and stem from the same founding population as do modern Asians and Europeans. One theory that attempted to explain this all away by involving multiple waves of migrants has recently collapsed under the weight of the contrary evidence.Archaeological sites in the Levant, Middle East, China and India all offer evidence of a previous colonisation of the Eurasian continent by modern humans long before the children of HgL3 and HgCT took possession of the world. What happened to these first people? Why don't we carry their genes today?Modern humans as we know them today bear traces of extinct relatives in their genome. We are left to wonder what brought about the end of the world for Neanderthals, Denisovans, Floresiensis and other yet to be named hominins. Why did our ancestors encounter an almost empty continent as they moved through Eurasia?During the last few years, a series of incredible discoveries have finally provided the evidence required to answer these and other profoundly important questions of our mysterious human origins.It is now possible to pinpoint the precise moment that doom fell upon the first modern humans of Eurasia in the form of a natural cataclysm that equally devastating for the Neanderthals and Denisovans. The myth of the aggressive conquering migrants from Africa killing their cousins is at last exposed for what it is, a sham, a wild guess with no scientific basis.Perhaps the first wave of modern humans entering Europe and Asia began their journey in Africa 200,000 - 150,000 years ago, but the recolonisation of Eurasia 70,000 - 60,000 years ago started from Australasia.This book calls for a paradigm displacement, but such a bold request requires detailed evidence. The only question remaining now is, whether you are ready to explore the evidence for yourself and follow the Forgotten Exodus?
