How New Humans Are Made

It is not okay to call something a miracle without even trying to understand it. This is human developmental biology (human embryology, in terms of cells and molecules) for everyone curious enough to see it through, from the perspective of the business of becoming human as individuals and as species; making new humans; how it happens (cells do it, ALL of it); and common variations of the process. It cannot be made quite simple and be kept quite true, but we will move as far toward simple as we can without losing touch with sound evidence. Variations from the normal version of the process, particularly malformations and twinning and chimerism, figure prominently in the story because there is no better way to learn about the usual than to study the unusual and see what differences in the endings these observable differences at the beginnings can make. In this book, when technical terminology is the only way, or the best way, to say what needs to be said, it is defined and explained making the words a worthwhile part of what is here to be learned. This book defines its own new field. We cannot claim to understand how anything human] works as human], with no effort at understanding the emergence of its form and functions. Old and new unanswered questions are waiting to be dug out from under old unquestioned answers about how becoming human unfolds. We will also address some popular and weighty, but deeply empty assertions about the circumstances and mechanisms of our beginnings and our ceaseless becoming. We will find fundamental questions from the humanities' unanswerable except from biology. Human developmental biology is a foundational discipline within the humanities.

In this stunningly original book, Richard Wrangham argues that it was cooking that caused the extraordinary transformation of our ancestors from apelike beings to Homo erectus. At the heart of Catching Fire lies an explosive new idea: the habit of eating cooked rather than raw food permitted the digestive tract to shrink and the human brain to grow, helped structure human society, and created the male-female division of labour. As our ancestors adapted to using fire, humans emerged as "the cooking apes". Covering everything from food-labelling and overweight pets to raw-food faddists, Catching Fire offers a startlingly original argument about how we came to be the social, intelligent, and sexual species we are today. "This notion is surprising, fresh and, in the hands of Richard Wrangham, utterly persuasive ... Big, new ideas do not come along often in evolution these days, but this is one." -Matt Ridley, author of Genome

From the first dog to the first beefalo, from farming to CRISPR, the human history of remaking nature When the 2020 Nobel Prize was awarded to the inventors of CRISPR, the revolutionary gene-editing tool, it underlined our amazing and apparently novel powers to alter nature. But as biologist Beth Shapiro argues in Life as We Made It, this phenomenon isn’t new. Humans have been reshaping the world around us for ages, from early dogs to modern bacteria modified to pump out insulin. Indeed, she claims, reshaping nature—resetting the course of evolution, ours and others’—is the essence of what our species does. In exploring our evolutionary and cultural history, Shapiro finds a course for the future. If we have always been changing nature to help us survive and thrive, then we need to avoid naive arguments about how we might destroy it with our meddling, and instead ask how we can meddle better. Brilliant and insightful, Life as We Made It is an essential book for the decades to come.

Winner of the W.W. Howells Book Prize from the American Anthropological Association and named one of the best science books of 2021 by Science News “DeSilva takes us on a brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution, in order to illustrate the powerful story of how a particular mode of movement helped make us one of the most wonderful, dangerous and fascinating species on Earth.”—Agustín Fuentes, Professor of Anthropology, Princeton University and author of Why We Believe: Evolution and the Human Way of Being “Breezy popular science at its best. . . . Makes a compelling case overall.”—Science News Blending history, science, and culture, a stunning and highly engaging evolutionary story exploring how walking on two legs allowed humans to become the planet’s dominant species. Humans are the only mammals to walk on two, rather than four legs—a locomotion known as bipedalism. We strive to be upstanding citizens, honor those who stand tall and proud, and take a stand against injustices. We follow in each other’s footsteps and celebrate a child’s beginning to walk. But why, and how, exactly, did we take our first steps? And at what cost? Bipedalism has its drawbacks: giving birth is more difficult and dangerous; our running speed is much slower than other animals; and we suffer a variety of ailments, from hernias to sinus problems. In First Steps, paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is. A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. Delving deeply into the story of our past and the new discoveries rewriting our understanding of human evolution, First Steps examines how walking upright helped us rise above all over species on this planet. First Steps includes an eight-page color photo insert.

A powerful, counterintuitive new theory of human nature arguing that our evolutionary success depends on our ability to be friendly--from a pair of trailblazing scientists and New York Times bestselling authors. For most of the approximately 200,000 years that our species has existed, we shared the planet with at least four other types of humans. They were smart, they were strong, and they were inventive. Neanderthals even had the capacity for spoken language. But, one by one, our hominid relatives went extinct. Why did we thrive? In delightfully conversational prose and based on years of his own original research, Brian Hare, professor in the department of evolutionary anthropology and the Center for Cognitive Neuroscience at Duke University, and his wife Vanessa Woods, a research scientist and award-winning journalist, offer a powerful, elegant new theory called "self-domestication" which suggests that we have succeeded not because we were the smartest or strongest but because we are the friendliest. This explanation flies in the face of conventional wisdom. Since Charles Darwin wrote about "evolutionary fitness," scientists have confused fitness with strength, tactical brilliance, and aggression. But what helped us innovate where other primates did not is our knack for coordinating with and listening to others. We can find common cause and identity with both neighbors and strangers if we see them as "one of us." This ability makes us geniuses at cooperation and innovation and is responsible for all the glories of culture and technology in human history. But this gift for friendliness comes at cost. If we perceive that someone is not "one of us," we are capable of unplugging them from our mental network. Where there would have been empathy and compassion, there is nothing, making us both the most tolerant and the most merciless species on the planet. To counteract the rise of tribalism in all aspects of modern life, Hare and Woods argue, we need to expand our empathy and friendliness to include people who aren't obviously like ourselves. Brian Hare's groundbreaking research was developed in close collaboration with Richard Wrangham and Michael Tomasello, giants in the field of cognitive evolution. Survival of the Friendliest explains both our evolutionary success and our potential for cruelty in one stroke and sheds new light onto everything from genocide and structural inequality to art and innovation.

There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.

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.

The New Humans reveals the very real possibility that we as a people are already evolving into the next higher species of hominids. The lives of the most advanced humans on Earth are portrayed as they struggle to survive in a post cold war, government run institution designed with dark secrets. Each member of this unique brotherhood is carrying a special ability that sets them apart from our world. The recorded life of the most powerful man in existence is examined as he discovers when he is a boy that he has an advanced brain. Tim Walker’s evolved brain gives him the ability for higher cognitive thinking, perceiving without the use of eyes and psychokinesis. He realizes at a young age that he is superior to us in every way. This knowledge coupled with his abilities makes Tim extremely dangerous to us as we try to cope with his existence. Also as we learn and understand why nature created such superior humans we start to realize that we are not the true heirs of the planet Earth after all ...
