In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. Lead researcher Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so. Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid.

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 shaped over eons. Rather than making women irrational - as the conventional and irredeemably sexist wisdom goes - the female hormonal cycle has been exquisitely fine-tuned to give women the advantages they needed to succeed in our ancestral environments, and perhaps also today.

Thousands of religions have adherents today, and countless more have existed throughout history. What accounts for this astonishing diversity? This extraordinarily ambitious and comprehensive book demonstrates how evolutionary systematics and philosophy can yield new insight into the development of organized religion. Lance Grande—a leading evolutionary systematist—examines the growth and diversification of hundreds of religions over time, highlighting their historical interrelationships.

How did humans come to be who we are? In his marvelous, eccentric, and widely lauded book Being a Beast, legal scholar, veterinary surgeon, and naturalist extraordinaire Charles Foster set out to understand the consciousness of animal species by living as a badger, otter, fox, deer, and swift. Now, he inhabits three crucial periods of human development to understand the consciousness of perhaps the strangest animal of all—the human being.

On his popular science blog, Pharyngula, PZ Myers has entertained millions of fans with his infectious love of evolutionary science and his equally infectious disdain for creationism, biblical literalism, intelligent design theory, and other products of godly illogic. This funny and fearless book collects and expands on some of his most popular writings, giving the religious fanaticism of our times the gleeful disrespect it deserves by skewering the apocalyptic fantasies, magical thinking, hypocrisies, and pseudoscientific theories advanced by religious fundamentalists of all stripes.

Author David Deamer addresses questions that are the cutting edge of research on the origin of life. In Assembling Life, he provides an overview of conditions on the early Earth four billion years ago and explains why freshwater hot springs are a plausible alternative to salty seawater as a site where life can begin.

We have long attributed man's violent, aggressive, competitive nature to his animal ancestry. But what if we are just as given to cooperation, empathy, and morality by virtue of our genes? What if our behavior actually makes us apes? What kind of apes are we?

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

The entirety of the human brain’s 4-billion-year story can be summarised as the culmination of five evolutionary breakthroughs, starting from the very first brains, all the way to the modern human brains. Each breakthrough emerged from new sets of brain modifications, and equipped animals with a new suite of intellectual faculties. These five breakthroughs are the organising map to this book, and they make up our itinerary for our adventure back in time. Each breakthrough also has fascinating corollaries to breakthroughs in AI.

Our Political Nature is the first book to reveal the hidden roots of our most deeply held moral values. It shows how political orientations across space and time arise from three clusters of measurable personality traits. These clusters entail opposing attitudes toward tribalism, inequality, and differing perceptions of human nature. Together, these traits are by far the most powerful cause of left-right voting, even leading people to regularly vote against their economic interests.

Just 150 years ago, most of our world was an unexplored wilderness. Our sense of its age was vastly off the mark. And what we believed to be the history of our own species consisted of fantastic myths and fairy tales; fossils, known for millennia, were seen as the bones of dragons and other imagined creatures. How did we learn so much so quickly? Remarkable Creatures celebrates the pioneers who replaced our fancies with the even more remarkable real story of how our world evolved.

For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as "junk," sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes.

What is human consciousness, and how is it possible? This question fascinates thinking people from poets and painters to physicists, psychologists, and philosophers. From Bacteria to Bach and Back is Daniel C. Dennett's brilliant answer, extending perspectives from his earlier work in surprising directions, exploring the deep interactions of evolution, brains, and human culture.

This audiobook takes you on an exciting journey into the past to uncover the story of the Denisovans. Hidden deep in the Denisova Cave in Siberia, their remains went unnoticed for centuries. But when scientists discovered them, it changed what we knew about human history.

Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

V. S. Ramachandran is at the forefront of his field - so much so that Richard Dawkins dubbed him the "Marco Polo of neuroscience". Now, in a major new work, Ramachandran sets his sights on the mystery of human uniqueness. Taking us to the frontiers of neurology, he reveals what baffling and extreme case studies can teach us about normal brain function and how it evolved.

Horses have a story to tell - one of resilience, sociability, and intelligence and of partnership with human beings. In The Horse, journalist and equestrienne Wendy Williams brings that story brilliantly to life. Williams chronicles the 56-million-year journey of horses as she visits with experts around the world, exploring what our biological affinities and differences can tell us about the bond between horses and humans and what our longtime companions might think and feel.

Over billions of years, ancient fish evolved to walk on land, reptiles transformed into birds that fly, and apelike primates evolved into humans that walk on two legs, talk, and write. For more than a century, paleontologists have traveled the globe to find fossils that show how such changes have happened.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Once, we humans could only observe evolution. Suddenly, we had conquered it. And yet, in Life as We Made It, evolutionary biologist Beth Shapiro argues that - despite how amazing our new technologies are - our ability to alter the course of evolution isn’t new. What is new is that where once we shaped evolution through brute force, we can now do it as artisans. That power comes not a moment too soon. If we are going to survive in the next few centuries, we must revise the book of life.
