Jim McKnight examines both the biological and the social evolutionary theories of the causation of homosexuality. He considers such questions as, how the discovery of a gay gene would fit with Darwin's theory of 'survival of the fittest'.

Provides a comprehensive summary of the research on the biology of homosexuality.

What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee. Although many details remain unresolved, the general conclusion is quite clear: A person's sexual orientation arises in large part from biological processes that are already underway before birth. LeVay also makes it clear that these lines of research have a lot of potential because--far from seeking to discover "what went wrong" in the lives of gay people, attempting to develop "cures" for homosexuality, or returning to traditional explanations that center on parent-child relationships, various forms of "training," or early sexual experiences--our modern scientists are increasingly seeing sexual variety as something to be valued, celebrated, and welcomed into society.

Christians affirm that everything exists because of God--from subatomic quarks to black holes. Science often claims to explain nature without including God at all. And thinking Christians often feel forced to choose between the two. But the good news is that we don't have to make a choice. Science does not overthrow the Bible. Faith does not require rejecting science. World-renowned scientist Francis Collins, author of The Language of God, along with fellow scientist Karl Giberson show how we can embrace both. Their fascinating treatment explains how God cares for and interacts with his creation while science offers a reliable way to understand the world he made. Together they clearly answer dozens of the most common questions people ask about Darwin, evolution, the age of the earth, the Bible, the existence of God and our finely tuned universe. They also consider how their views stack up against the new atheists as well as against creationists and adherents of intelligent design. The authors disentangle the false conclusions of Christians and atheists alike about science and evolution from the actual results of research in astronomy, physics, geology and genetics. In its place they find a story of the grandeur and beauty of a world made by a supremely creative God.

WINNER OF THE 2020 GOVERNOR GENERAL'S LITERARY AWARD FOR NONFICTION “Wondrously and elegantly written in language that astonishes and moves the reader…This is an important book: an emotional and intellectual tour de force.” —Jane Urquhart An experimental memoir about Partition, immigration, and generational storytelling, This Red Line Goes Straight to Your Heart weaves together the poetry of memory with the science of embodied trauma, using the imagined voices of the past and the vital authority of the present. We begin with a man off balance: one in one thousand, the only child in town whose polio leads to partial paralysis. We meet his future wife, chanting Hai Rams for Gandhiji and choosing education over marriage. On one side of the line that divides this book, we follow them as their homeland splits in two and they are drawn together, moving to Canada and raising their children in mining towns and in crowded city apartments. And when we turn the book over, we find the daughter's tale—we see how the rupture of Partition, the asymmetry of a father's leg, the virus of a mother's rage, makes its way to the next generation. Told through the lenses of biology, physics, history and poetry, this is a memoir that defies form and convention to immerse the reader in the feeling of what remains when we've heard as much of the truth as our families will allow, and we're left to search for ourselves among the pieces they've carried with them.

Now that people are aware that data can make the difference in an election or a business model, data science as an occupation is gaining ground. But how can you get started working in a wide-ranging, interdisciplinary field that’s so clouded in hype? This insightful book, based on Columbia University’s Introduction to Data Science class, tells you what you need to know. In many of these chapter-long lectures, data scientists from companies such as Google, Microsoft, and eBay share new algorithms, methods, and models by presenting case studies and the code they use. If you’re familiar with linear algebra, probability, and statistics, and have programming experience, this book is an ideal introduction to data science. Topics include: Statistical inference, exploratory data analysis, and the data science process Algorithms Spam filters, Naive Bayes, and data wrangling Logistic regression Financial modeling Recommendation engines and causality Data visualization Social networks and data journalism Data engineering, MapReduce, Pregel, and Hadoop Doing Data Science is collaboration between course instructor Rachel Schutt, Senior VP of Data Science at News Corp, and data science consultant Cathy O’Neil, a senior data scientist at Johnson Research Labs, who attended and blogged about the course.
