For all that science knows about the living world, notes David P. Barash, there are even more things we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

The Origin of Humankind is Richard Leakey's personal view of the development of Homo sapiens. At the heart of his new picture of evolution is the introduction of a heretical notion: Once the first apes walked upright, the evolution of modern humans became possible and perhaps inevitable. From this one evolutionary step comes all the other evolutionary refinements and distinctions that set the human race apart from the apes.

Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25 percent of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals but not because we are evolutionary outliers.

The world is in crisis! What is the solution? Ultimately, we have to find the redeeming, and thus transforming, understanding of our psychologically troubled human condition. And it is precisely that dreamed-of insight, and its now desperately needed transformation of our lives, that Australian biologist Jeremy Griffith presents in this book.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

Humans, it turns out, are intrinsically wired to seek short-term success at the expense of long-term prosperity. Kristian Rönn, an entrepreneur formerly affiliated with the University of Oxford’s Future of Humanity Institute, calls these deeply rooted impulses “Darwinian demons.” These forces, a by-product of natural selection, can lead us to act in shortsighted ways that harm others—and even imperil our survival as a species. If this evolutionary glitch is left unchecked, the consequences will grow in magnitude as the power of technology accelerates.

Why is the world the way it is? How did we get here? Does everything happen for a reason, or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world.

There are rare moments in time when we make choices that irreversibly change the world, and our lives, forever. Today is one of those moments. Scientists, engineers and philosophers alike warn us that without a radical shift in our thinking, we are on track to be the last generation of pure humans that the world will know. Within a single generation we will devolve into a hybrid species of synthetic bodies, Artificial Intelligence (AI), and computer chips that limit our ability to think, to love, and to adapt to the conditions of the emerging world in a healthy way.

Are the ways we look at menopause all wrong? Historian Susan Mattern says yes, and The Slow Moon Climbs reveals just how wrong we have been. Taking listeners from the rainforests of Paraguay to the streets of Tokyo, Mattern draws on historical, scientific, and cultural research to reveal how our perceptions of menopause developed from prehistory to today. For most of human history, people had no word for menopause and did not view it as a medical condition. Rather, in traditional foraging and agrarian societies, it was a transition to another important life stage.

For decades medical science has believed that genes determined our biological destiny. Now the new genetics has changed that assumption forever. You will always have the genes you were born with, but genes are dynamic, responding to everything we think, say, and do. Suddenly they've become our strongest allies for personal transformation. When you make lifestyle choices that optimize how your genes behave, you can reach for a state of health and fulfillment undreamed of even a decade ago.

We are now on the doorstep of a fourth change brought about by two technologies: AI and robotics. The Fourth Age provides extraordinary background information on how we got to this point, and how - rather than what - we should think about the topics we’ll soon all be facing: machine consciousness, automation, employment, creative computers, radical life extension, artificial life, AI ethics, the future of warfare, superintelligence, and the implications of extreme prosperity.

In The Social Leap, William von Hippel lays out a revolutionary hypothesis, tracing human development through three critical evolutionary inflection points to explain how events in our distant past shape our lives today. From the mundane, such as why we exaggerate, to the surprising, such as why we believe our own lies and why fame and fortune are as likely to bring misery as happiness, the implications are far-reaching and extraordinary.

How did human minds become so different from those of other animals? What accounts for our capacity to understand the way the physical world works, to think ourselves into the minds of others, to gossip, read, tell stories about the past, and imagine the future? These questions are not new: they have been debated by philosophers, psychologists, anthropologists, evolutionists, and neurobiologists over the course of centuries. One explanation widely accepted today is that humans have special cognitive instincts.

Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs - they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken - imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time.

«Nos encantaría descubrir que cada especie tiene un reloj biológico en sus células, porque, de existir ese reloj y si fuéramos capaces de dar con él, quizá pudiéramos pararlo y de ese modo volvernos eternos», le plantea Arsuaga a Millás en este libro en el que la ciencia se entrelaza con la literatura. El paleontólogo desvela aspectos esenciales de nuestra existencia al escritor, y se debate sobre la conveniencia de transmitir su visión azarosa de la vida a un Millás a dieta que descubre que la vejez es un país en el que todavía se siente extranjero.

It is difficult to conceive of the vast scale of the history of life on Earth, from the very first living organisms sparking into life in hydrothermal deep-sea vents to the dizzying diversity of life today. The evolution of life is a sweeping epic of a tale, with twists and turns, surprising heroes and unlikely survivors. The Earth beautifully distils this complex story into a meaningful scale. In taking a closer look at 47 carefully selected organisms over 15 periods in our planetary history, this audiobook tells the whole story of life on Earth.

In Origin Story, medical historian Howard Markel recounts the two-year period (1858 to 1860) of Darwin's writing of On the Origin of Species through its spectacular success and controversy. Simultaneously, Markel delves into the mysterious health symptoms Darwin developed, combing the literature to emerge with a cogent diagnosis of a case that has long fascinated medical historians.

Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how.

Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes!" Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original arguments - drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy - that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally.
