Book Description
This book examines an important paradigm shift in biology: Plants and animals, traditionally viewed as individuals, are now considered to be complex systems and host to a plethora of microorganisms. After first presenting historical aspects of microbiota research, bacterial compositions of individual microbiomes and the critical analysis of current methods, the book discusses how microbial communities inside the human body are profoundly affected by numerous factors, such as macro- and micro-nutrients, physical exercise, antibiotics, gender and age. As described by current research, the author highlights how microbiomes contribute to the fitness of the host by providing nutrients, inhibiting pathogens, aiding in the storage of fat during pregnancy, and contributing to development and behavior. The author not only focusses on prokaryotic components in microbiomes, but also addresses single-cell eukaryotes and viruses. This follow-up to the successful book The Hologenome Concept: Human, Animal and Plant Microbiota, published in 2013, provides a contemporary overview of microbiomes. It appeals to anyone working in the life sciences and biomedicine.

The Beast Within
Author: Jessica Serra
Publisher: JHU Press
ISBN: 1421448084
Category : Science
Languages : en
Pages : 195
Book Description
How different from animals are we really? Are humans the only creatures who love, laugh, cry, possess morals, and wage war? In The Beast Within, scientific researcher and ethologist Jessica Serra upends the assumptions that underpin our very human hypothesis that we possess a superior place in the hierarchy of organisms on Earth. How did we come to think of our animality as standing in opposition to our humanity—and does this reasoning have a scientific basis? Through the fascinating discoveries made by ethologists, anthropologists, and archeologists, Serra deciphers our behaviors in light of their animal roots and demystifies ideas about how different animals are from humans. She compares human behaviors with those exhibited by other species in chapters spanning topics as varied as sex, morality, emotions, intelligence, and family. Exploring the evolution of various animal species, as well as the evolution of historical ideas about humanity and animality, Serra theorizes that human behaviors and motivations may hold more in common with those of animals than we think. These explorations of scientific findings encourage us to reconsider how much we have truly removed ourselves from "the beast within."

Hormonal
Author: Martie Haselton
Publisher: Little, Brown Spark
ISBN: 0316369195
Category : Health & Fitness
Languages : en
Pages : 234
Book Description
The hidden intelligence of hormones and their role in empowering women to succeed sexually, reproductively, and socially. Did you know women walk more, eat less, socialize more, meet more men, dance more, and flirt more when they're ovulating? Or that PMS may have evolved to get rid of boyfriends with unfit sperm? Behind the "fickle" differences in what women find sexy about men, or what they like to wear, there's a hidden adaptive intelligence that has been shaped over eons. In this provocative and paradigm-shattering book, Martie Haselton, the world's leading researcher on sexuality and the ovulation cycle, takes a deep, revealing look at the biological processes that so profoundly influence our behavior and sets forth a radical new understanding of women's bodies, minds, and sexual relationships, one that embraces hormonal cycles as adaptive solutions to genuine biological challenges. At the core of Hasleton's new Darwinian feminism is her remarkable discovery that humans, like our animal cousins, possess a special phase of sexuality, called estrus, which comes with a host of physiological and behavioral changes. Rigorously researched, entertaining, and empowering, Hormonal offers women deep new insights into their bodies, brains, relationships, and affairs, allowing them to make better-informed choices about sex, marriage, friendship, contraception, and more. Above all, Hormonal is a clarion call to appreciate and embrace the genius of female biology.

ISBN: 1633888002
Category : Science
Languages : en
Pages : 325
Book Description
For as long as humans have been on Earth, we have looked up to the stars for clues to our own existence. Medical doctor and evolutionary biologist William B. Miller, Jr. suggests that we may find more meaningful solutions at the end of a microscope rather than a telescope. Using powerful analogies and exacting science, Bioverse explores the wonders of the perpetual partnership between our personal cells and the microbial world, resulting in an entirely new view of our living planet. To understand life in all its varieties, we must undertake to understand our cells. While the partnership between our cells and our microbes has largely been thought of as that of “host” and “guest,” Millerrevealsthetrue partnership under which both our microbial fraction and our own personal cells conduct a life-long dialogue, redefining our traditional conceptions of intelligence and problem-solving. This radical new approach explains exactly how our human choices are centered within the same cellular rules that enable our cells to seamlessly sustain our lives. We are now entering the “Era of the Cell,” a time in history during which medical and scientific innovations have spurred growth far beyond ever imagined by our ancestors. For the first time, we are not only building machines to enhance our lives but engineering living organisms to assist our futures. From the biological origins of evolution to the invention of the compound microscope by a Dutch lens maker in the 17th century, to new research that reveals surprising links between our microbiome and our moods and behavior, and surprising stories of the cellular world from the deepest oceans, wildest jungles, and outer reaches of our solar system, Millerintroduces readers to a greater understanding of our impact on the planet and the world’s reciprocal impact on each of us. By exploring the extent of our deeply integrated cellular world, Bioverse provides profound insights about ourselves, our health and well-being, our social systems, and our permanent relationship to the planet and the cosmos.

Objection
Author: Debra Lieberman
Publisher: Oxford University Press
ISBN: 0190491302
Category : Psychology
Languages : en
Pages : 265
Book Description
Why do we consider incest wrong, even when it occurs between consenting adults unable to have children? Why are words that gross us out more likely to be deemed "obscene" and denied the protection of the First Amendment? In a world where a gruesome photograph can decisively influence a jury and homosexual behavior is still condemned by some as "unnatural," it is worth asking: is our legal system really governed by the power of reason? Or do we allow a primitive human emotion, disgust, to guide us in our lawmaking? In Objection, psychologists Debra Lieberman and Carlton Patrick examine disgust and its impact on the legal system to show why the things that we find stomach-turning so often become the things that we render unlawful. Shedding light on the evolutionary and psychological origins of disgust, the authors reveal how ancient human intuitions about what is safe to eat or touch, or who would make an advantageous mate, have become co-opted by moral systems designed to condemn behavior and identify groups of people ripe for marginalization. Over time these moral stances have made their way into legal codes, and disgust has thereby served as the impetus for laws against behaviors almost universally held to be "disgusting" (corpse desecration, bestiality) - and as the implicit justification for more controversial prohibitions (homosexuality, use of pornography). Written with a critical eye on current events, Lieberman and Patrick build a case for a more reasoned approach to lawmaking in a system that often confuses "gross" with "wrong."
