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.

Well, it’s really a war. Your enemies are your own genes, backed by millions of years of evolution, and the only way to win is to outsmart them. Renowned surgeon and founder of Gundry MD, Dr. Steven Gundry’s revolutionary book shares the health secrets other doctors won’t tell you: • Why plants are “good” for you because they’re “bad” for you, and meat is “bad” because it’s “good” for you • Why plateauing on this diet is actually a sign that you’re on the right track • Why artificial sweeteners have the same effects as sugar on your health and your waistline • Why taking antacids, statins, and drugs for high blood pressure and arthritis masks health issues instead of addressing them Along with the meal planner, 70 delicious recipes, and inspirational stories, Dr. Gundry’s easy-to-memorize tips will keep you healthy and on course.
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.

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 Tears of the Cheetah in PDF and EPUB The history of life on Earth is dominated by extinction events so numerous that over 99.9% of the species ever to have existed are gone forever. If animals could talk, we would ask them to recall their own ancestries, in particular the secrets as to how they avoided almost inevitable annihilation in the face of daily assaults by predators, climactic cataclysms, deadly infections and innate diseases. In Tears of the Cheetah, medical geneticist and conservationist Stephen J. O'Brien narrates fast-moving science adventure stories that explore the mysteries of survival among the earth's most endangered and beloved wildlife. Here we uncover the secret histories of exotic species such as Indonesian orangutans, humpback whales, and the imperiled cheetah-the world's fastest animal which nonetheless cannot escape its own genetic weaknesses. Among these genetic detective stories we also discover how the Serengeti lions have lived with FIV (the feline version of HIV), where giant pandas really come from, how bold genetic action pulled the Florida panther from the edge of extinction, how the survivors of the medieval Black Death passed on a genetic gift to their descendents, and how mapping the genome of the domestic cat solved a murder case in Canada. With each riveting account of animal resilience and adaptation, a remarkable parallel in human medicine is drawn, adding yet another rationale for species conservation-mining their genomes for cures to our own fatal diseases. Tears of the Cheetah offers a fascinating glimpse of the insight gained when geneticists venutre into the wild.
