In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an arduous and even deadly ritual called a “lek.” To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers. When achieved, consummation with a female takes seconds.

For centuries, the dietary needs of dogs were a secondary consideration. Our loyal companions, domesticated from wolves, lived on scraps from human meals, whatever was available and convenient at the time. In rural communities, a dog’s diet might have included leftovers, bones, and whatever they could scavenge. There was little thought given to balancing nutrients, matching caloric needs to activity levels, or preventing diet-related diseases. The invention of commercial dog food in the mid-19th century marked a pivotal shift.

Find a missing book. That was the job the woman in the Doc Martens gave us. Easy money, right? Only now it seems she's actually an ancient, powerful sorcerer, and the book is a Book of Power that doesn't want to be found.

So now we've got one spectacularly displeased sorcerer, a hungry, still-missing book, a dentist with bad hygiene, and a neighbourhood having some reality issues to deal with. Plus about a day before the book turns our world - and us - inside out.

Animal scientists have long considered domestic livestock to be too dumb to know how to eat right, but the lifetime research of animal behaviorist Fred Provenza and his colleagues has debunked this myth. Their work shows that when given a choice of natural foods, livestock have an astoundingly refined palate, nibbling through the day on as many as fifty kinds of grasses, forbs, and shrubs to meet their nutritional needs with remarkable precision.

From beloved, award-winning poet Aimee Nezhukumatathil comes a debut work of nonfiction - a collection of essays about the natural world, and the way its inhabitants can teach, support, and inspire us.

When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don't see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones and Bird Songs guides the listener through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter.

In this landmark book of popular science, Daniel E. Lieberman - chair of the department of human evolutionary biology at Harvard University and a leader in the field - gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease.

Effective altruism is built upon the simple, but profound, idea that living a fully ethical life involves doing the "most good you can do". Such a life requires an unsentimental view of charitable giving: To be a worthy recipient of our support, an organization must be able to demonstrate that it will do more good with our money or our time than other options open to us. Singer introduces us to an array of remarkable people who are restructuring their lives in accordance with these ideas and shows how living altruistically often leads to greater personal fulfillment.
