Some women could be teachers or seamstresses, but career options were few. Certainly no women were doctors. But Elizabeth refused to accept the common beliefs that women weren’t smart enough to be doctors, or that they were too weak for such hard work. And she would not take no for an answer. Although she faced much opposition, she worked hard and finally—when she graduated from medical school and went on to have a brilliant career—proved her detractors wrong. This inspiring story of the first female doctor shows how one strong-willed woman opened the doors for all the female doctors to come.

    Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this--the greatest biography of all--is one in whose closing pages we find ourselves.--from OriginsIn Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.Rhodes's accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

    Rich illustrations, systematic resumes, and extensive citations make it a valuable references source.

    A group of young scientists, under the guidance of Dr. George Church, the most brilliant geneticist of our time, works to make fantasy reality by sequencing the DNA of a frozen woolly mammoth harvested from above the Arctic circle, and splicing elements of that sequence into the DNA of a modern elephant. Will they be able to turn the hybrid cells into a functional embryo and bring the extinct creatures to life in our modern world?Along with Church and his team of Harvard scientists, a world-famous conservationist and a genius Russian scientist plan to turn a tract of the Siberian tundra into Pleistocene Park, populating the permafrost with ancient herbivores as a hedge against an environmental ticking time bomb.

    Yet today there is only one—homo sapiens. What happened to the others? And what may happen to us?In this first volume of the full-color illustrated adaptation of his groundbreaking book, renowned historian Yuval Harari tells the story of humankind’s creation and evolution, exploring the ways in which biology and history have defined us and enhanced our understanding of what it means to be “human.” From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens challenges us to reconsider accepted beliefs, connect past developments with contemporary concerns, and view specific events within the context of larger ideas. Featuring 256 pages of full-color illustrations and easy-to-understand text covering the first part of the full-length original edition, this adaptation of the mind-expanding book furthers the ongoing conversation as it introduces Harari’s ideas to a wide new readership.

    So who better than an alien to explain it all? Enter Bloort 183, a scientist from an asexual alien race threatened by disease, who's been charged with researching the fundamentals of human DNA and evolution and laying it all out in clear, simple language so that even his slow-to-grasp-the-point leader can get it. In the hands of the award-winning writer Mark Schultz, Bloort's predicament becomes the means of giving even the most science-phobic reader a complete introduction to the history and science of genetics that's as easy to understand as it is entertaining to read.

    Frances E. Jensen, a mother, teacher, researcher, and internationally known expert in neurology, introduces us to the mystery and magic of the teen brain. One of the first books to focus exclusively on the neurological development of adolescents, The Teenage Brain presents new findings, dispels widespread myths, and provides practical suggestions for negotiating this difficult and dynamic life stage for both adults and adolescents.Interweaving easy-to-follow scientific data with anecdotes drawn from her experiences as a parent, clinician, and public speaker, Dr. Jensen explores adolescent brain functioning and development, including learning and memory, and investigates the impact of influences such as drugs, multitasking, sleep, and stress. The Teenage Brain reveals how: Adolescents may not be as resilient to the effects of drugs as we previously thought. Occasional use of marijuana has been shown to cause lingering memory problems, and long-term use can affect later adulthood I.Q. Multi-tasking causes divided attention and can reduce learning ability. Emotionally stressful situations in adolescence can have permanent effects on mental health, and may lead to higher risk for certain neuropsychiatric disorders such as depression.Rigorous yet accessible, warm yet direct, The Teenage Brain sheds new light on young adults, and provides practical suggestions for how parents, schools, and even the legal system can better help them during this crucial period.

    

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    Although several books have been written about this surprising event, known as the Cambrian explosion, none has explained why it occurred. Indeed, none was able to. Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's controversial but increasingly accepted "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Drawing on evidence not just from biology, but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating account of a young scientist's intellectual journey, and a celebration of the scientific method.

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.
