Download and read online Mapping Human History in PDF and EPUB Until just a few years ago, we knew surprisingly little about the 150,000 or so years of human existence before the advent of writing. Some of the most momentous events in our past - including our origins, our migrations across the globe, and our acquisition of language - were veiled in the uncertainty of 'prehistory'. That veil is being lifted at last by geneticists and other scientists. Mapping Human History is nothing less than an astonishing 'history of prehistory'. Steve Olson travelled through four continents to gather insights into the development of humans and our expansion throughout the world. He describes, for example, new thinking about how centres of agriculture sprang up among disparate foraging societies at roughly the same time. He tells why most of us can claim Julius Caesar and Confucius among our forebears. He pinpoints why the ways in which the story of the Jewish people jibes with, and diverges from, biblical accounts. And using very recent genetic findings, he explodes the myth that human races are a biological reality.
Download and read online Why We Get Sick in PDF and EPUB The next time you get sick, consider this before picking up the aspirin: your body may be doing exactly what it's supposed to. In this ground-breaking book, two pioneers of the science of Darwinian medicine argue that illness as well as the factors that predispose us toward it are subject to the same laws of natural selection that otherwise make our bodies such miracles of design. Among the concerns they raise: When may a fever be beneficial? Why do pregnant women get morning sickness? How do certain viruses "manipulate" their hosts into infecting others? What evolutionary factors may be responsible for depression and panic disorder? Deftly summarizing research on disorders ranging from allergies to Alzheimer's, and form cancer to Huntington's chorea, Why We Get Sick, answers these questions and more. The result is a book that will revolutionize our attitudes toward illness and will intrigue and instruct lay person and medical practitioners alike. From the Trade Paperback edition.
Download and read online Human origins in PDF and EPUB Ever since the recognition of the Neanderthals as an archaic form of human in the mid-nineteenth century, the fossilized bones of extinct humans have been used by paleoanthropologists to explore human origins. These bones tell the story of how the earliest humans first emerged in Africa some 6 to 7 million years ago. The bones also reveal that as humans became anatomically and behaviorally more modern, they swept out of Africa in waves into Asia, Europe, and finally into the New World. Even as paleoanthropologists continued to make important discoveries, experts in genetics were looking at the human species from a very different angle. In 1953 James Watson and Francis Crick first envisioned the double helix structure of DNA, the basic building block of all life. In the 1970s it was shown that humans share 98.7 percent of their genes with the great apes--that in fact genetically we are more closely related to chimpanzees than chimpanzees are to gorillas. And most recently the entire human genome has been mapped--we now know where each of the genes are located on the DNA strands that make up our chromosomes. In Human Origins: What Bones and Genomes Tell Us about Ourselves, two of the worlds foremost scientists, geneticist Rob DeSalle and paleoanthropologist Ian Tattersall, show how research into the human genome confirms what fossil bones have told us about human origins. This unprecedented integration of the fossil and genomic records provides the most complete understanding possible of humanity's place in nature, its emergence from the rest of the living world, and the evolutionary processes that have molded human populations to be what they are today.
Download and read online Race and Science in PDF and EPUB During the course of American history, scientific theories have been used to legitimate racial ideas that in turn have been important in creating and interpreting the law. Race and Science collects essays from leading voices in law, history, history of science, botany, and the social sciences, resulting in a rich and comprehensive multidisciplinary exploration of the roots of and the scientific challenges to racial essentialism. The notion that someone's racial identity and characteristics define everything of importance about them has become deeply embedded in American culture, society, and science. These essays illuminate the roots of this belief and present case studies that explore how and why natural and social scientists have challenged these racist views. Race and Science will be of interest to historians, social scientists, educators, and scientists, and others interested in racism as a phenomenon in American culture.
Download and read online Pandora s Seed in PDF and EPUB In The Journey of Man, renowned geneticist and anthropologist Spencer Wells traced human evolution back to our earliest ancestors, creating a remarkable and readable map of our distant past. Now, in his thrilling and thoughtful new book, he examines our cultural inheritance in order to find the turning point that led us to the path we are on today, one he believes we must veer from in order to survive. Pandora's Seed takes us on a powerful and provocative globe-trotting tour of human history, back to a seminal event roughly 10,000 years ago, when our species made a radical shift in its way of life: we became farmers rather than hunter-gatherers, setting in motion a momentous chain of events that could not have been foreseen at the time. Although this decision to control our own food supply is what propelled us into the modern world, Wells demonstrates with the latest genetic and anthropological data that such a dramatic shift in lifestyle had a downside that we're only beginning to recognize. Growing grain crops ultimately made the planet more crowded, sedentary and unhealthy. The expanding population and the need to apportion limiting resources such as water created hierarchies and inequalities. The desire to control - and no longer cooperate with - nature altered the concept of religion, making deities fewer and more influential, foreshadowing today's fanaticisms. The proximity of humans and animals bred diseases that metastasized over time. Freedom of movement and choice were replaced by a pressure to work that is the forebear of anxiety and depression millions feel today. Wells then offers a hopeful prescription for altering a life to which we were always ill-suited, changing priorities and self-destructive appetites before it's too late. A riveting and accessible scientific detective story, Pandora's Seed is an eye-opening book for anyone fascinated by the past and concerned about the future.
Download and read online Human Evolution in PDF and EPUB What makes us human? How did we develop language, thought and culture? Why did we survive, and other human species fail? The past 12,000 years represent the only time in the sweep of human history when there has been only one human species. How did this extraordinary proliferation of species come about - and then go extinct? And why did we emerge such intellectual giants? The tale of our origins has inevitably been told through the 'stones and bones' of the archaeological record, yet Robin Dunbar shows it was our social and cognitive changes rather than our physical development which truly made us distinct from other species.

Download and read online DNA USA A Genetic Portrait of America in PDF and EPUB Crisscrossing the continent, a renowned geneticist provides a groundbreaking examination of America through its DNA. The best-selling author of The Seven Daughters of Eve now turns his sights on the United States, one of the most genetically variegated countries in the world. From the blue-blooded pockets of old-WASP New England to the vast tribal lands of the Navajo, Bryan Sykes takes us on a historical genetic tour, interviewing genealogists, geneticists, anthropologists, and everyday Americans with compelling ancestral stories. His findings suggest: • Of Americans whose ancestors came as slaves, virtually all have some European DNA. • Racial intermixing appears least common among descendants of early New England colonists. • There is clear evidence of Jewish genes among descendants of southwestern Spanish Catholics. • Among white Americans, evidence of African DNA is most common in the South. • European genes appeared among Native Americans as early as ten thousand years ago. An unprecedented look into America's genetic mosaic and how we perceive race, DNA USA challenges the very notion of what we think it means to be American.
Download and read online An Imaginary Tale in PDF and EPUB Today complex numbers have such widespread practical use--from electrical engineering to aeronautics--that few people would expect the story behind their derivation to be filled with adventure and enigma. In An Imaginary Tale, Paul Nahin tells the 2000-year-old history of one of mathematics' most elusive numbers, the square root of minus one, also known as i. He recreates the baffling mathematical problems that conjured it up, and the colorful characters who tried to solve them. In 1878, when two brothers stole a mathematical papyrus from the ancient Egyptian burial site in the Valley of Kings, they led scholars to the earliest known occurrence of the square root of a negative number. The papyrus offered a specific numerical example of how to calculate the volume of a truncated square pyramid, which implied the need for i. In the first century, the mathematician-engineer Heron of Alexandria encountered I in a separate project, but fudged the arithmetic; medieval mathematicians stumbled upon the concept while grappling with the meaning of negative numbers, but dismissed their square roots as nonsense. By the time of Descartes, a theoretical use for these elusive square roots--now called "imaginary numbers"--was suspected, but efforts to solve them led to intense, bitter debates. The notorious i finally won acceptance and was put to use in complex analysis and theoretical physics in Napoleonic times. Addressing readers with both a general and scholarly interest in mathematics, Nahin weaves into this narrative entertaining historical facts and mathematical discussions, including the application of complex numbers and functions to important problems, such as Kepler's laws of planetary motion and ac electrical circuits. This book can be read as an engaging history, almost a biography, of one of the most evasive and pervasive "numbers" in all of mathematics.
