In 1966, simple Darwinism, which holds that evolution functions primarily at the level of the individual organism, was threatened by opposing concepts such as group selection, a popular idea stating that evolution acts to select entire species rather than individuals. George Williams's famous argument in favor of the Darwinists struck a powerful blow to those in opposing camps. His Adaptation and Natural Selection, now a classic of science literature, is a thorough and convincing essay in defense of Darwinism; its suggestions for developing effective principles for dealing with the evolution debate and its relevance to many fields outside biology ensure the timelessness of this critical work.

     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    Just a half century ago, this idea was revolutionary. In April 1953, James Watson and Francis Crick published in Nature their groundbreaking work revealing the double helix structure of DNA. While this discovery received wide attention from both mainstream media and the academic community, it was just one part of the bigger story in this history of molecular biology. By the mid-1950s, the scientific community confirmed that genes were indeed comprised of DNA; they just needed to crack the genetic code—and the race was on. Life’s Greatest Secret is the full and rich history of this challenge and the characters—many of whom were not biologists—whose work contributed to this grand scientific endeavor: mathematician and father of cybernetics Norbert Wiener, physicist Erwin Schrödinger, information theorist Claude Shannon, and biologists Jacques Monod and Marshall Nirenberg.In Life’s Greatest Secret, science historian and zoologist Matthew Cobb shows that the race to crack the genetic code was mostly a matter of craft—individuals or small groups struggling with ideas and concepts as much as they were with facts, trying to find the right experiment to answer the right questions, even if they didn’t know what the questions were, and finding that, even when the most definitive answer served mostly to reveal more ignorance, whether in 1953, with Watson and Crick, or in 1961, when Nirenberg and Matthaei showed how DNA codes for specific amino acids, and again and again thereafter, or in 2000, with the first publication of a human genome. Each discovery was a leap forward in our understanding of the natural world and our place within in, akin to the discoveries of Galileo and Einstein in the realm of physics, or the publication of Darwin’s On the Origin of Species. And each served to show how much bigger the problem was that anyone had previously imagined, a trend that continues, as Cobb shows, even today, whether we are discussing gene regulation, epigenetics, or GMOs.Life’s Greatest Secret is a story of ideas and of experimentation, of ingenuity, insight, and dead-ends, in the hunt to make the greatest discovery of twentieth century biology. Ultimately, though, this is a story of humans exploring what it is that makes us human.

    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.

    But what were and are the true potentates of our planet? Insects, says Scott Richard Shaw—millions and millions of insect species. Starting in the shallow oceans of ancient Earth and ending in the far reaches of outer space—where, Shaw proposes, insect-like aliens may have achieved similar preeminence—Planet of the Bugs spins a sweeping account of insects’ evolution from humble arthropod ancestors into the bugs we know and love (or fear and hate) today. Leaving no stone unturned, Shaw explores how evolutionary innovations such as small body size, wings, metamorphosis, and parasitic behavior have enabled insects to disperse widely, occupy increasingly narrow niches, and survive global catastrophes in their rise to dominance. Through buggy tales by turns bizarre and comical—from caddisflies that construct portable houses or weave silken aquatic nets to trap floating debris, to parasitic wasp larvae that develop in the blood of host insects and, by storing waste products in their rear ends, are able to postpone defecation until after they emerge—he not only unearths how changes in our planet’s geology, flora, and fauna contributed to insects’ success, but also how, in return, insects came to shape terrestrial ecosystems and amplify biodiversity. Indeed, in his visits to hyperdiverse rain forests to highlight the current insect extinction crisis, Shaw reaffirms just how crucial these tiny beings are to planetary health and human survival. In this age of honeybee die-offs and bedbugs hitching rides in the spines of library books, Planet of the Bugs charms with humor, affection, and insight into the world’s six-legged creatures, revealing an essential importance that resonates across time and space.

    It infected nearly one-third of the world’s population and killed ten percent of those it struck. In its wake, schools and businesses closed, hospitals became overwhelmed, and the sick spilled out into makeshift care centers in public spaces. Policemen, public transportation workers, and everyday citizens in face masks were a common—and eerie—sight. Yet, discussion of this global pandemic often takes a backseat to World War I and other contemporary events.

    The prolonged encounter between the Cro-Magnons and the archaic Neanderthals and between 45,000 and 30,000 years ago was one of the defining moments of history. The Neanderthals survived for some 15,000 years in the face of the newcomers, but were finally pushed aside by the Cro-Magnons' vastly superior intellectual abilities and cutting-edge technologies, which allowed them to thrive in the intensely challenging climate of the Ice Age.What do we know about this remarkable takeover? Who were the first modern Europeans and what were they like? How did they manage to thrive in such an extreme environment? And what legacy did they leave behind them after the cold millennia? The age of the Cro-Magnons lasted some 30,000 years?longer than all of recorded history. Cro-Magnon is the story of a little known, yet seminal, chapter of human experience.

    Berra, whose "Darwin: The Man" lectures are in high demand worldwide, tells the fascinating story of the person and the idea that changed everything.
