Human Genetics

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 Human Blend is a science-fiction adventure centered around a group of thieves living in a future where physical alterations and enhancements are a common occurrence. If you could take on a body with any features you wanted, what would it look like? And what would you do with them - human or otherwise?

For the last three billion years or so, life on Earth was shaped by natural forces. Evolution tended to happen slowly, with species crafted across millennia. Then, a few hundred thousand years ago, along came a bolshie, big-brained, bipedal primate we now call Homo sapiens, and with that, the Earth’s natural history came to an abrupt end. We are now living through the post-natural phase, where humans have become the leading force shaping evolution. This audiobook considers the many ways that we’ve altered the DNA of living things and changed the fate of life on earth.

In the new essays collected here, an interdisciplinary group of scholars asks age-old questions about the nature and well-being of humans in the context of a revolutionary new biotechnology - one that has the potential to change the genetic make-up of both existing people and future generations. Welcoming listeners who study related issues and those not yet familiar with the formal study of bioethics, the authors of these essays open up a conversation about the ethics of gene editing.

This dynamic chronicle of the race to find the "missing links" between humans and apes transports readers into the highly competitive world of fossil hunting and into the lives of the ambitious scientists intent on pinpointing the dawn of humankind. The quest to find where and when the earliest human ancestors first appeared is one of the most exciting and challenging of all scientific pursuits.

What makes us human? Why are we the only animals who wear clothes, drive cars, trawl the internet, and fly helicopters on Mars? It’s all because we’ve learnt to talk, yet remarkably, we still don’t know how we did it. Speech! suggests an answer that’s been hiding in plain sight - the simple yet radical shift that turned our analog grunts and shrieks into words. But, its consequences are far from simple: being able to share ideas through language was an evolutionary tipping point - it allowed us to link up our minds.

If we are, in part, a product of our genes, can free will exist? Incisive and engaging, this indispensable tour of evolutionary biology runs the gamut of contemporary debates, from science and religion to our place in the universe.

Akshaya is the hybrid daughter of a human mother and an alloy, a genetically engineered posthuman—and she’s the future of life on the planet Meru. But not if the determined Akshaya can help it. Before choosing where her future lies, she wants to circumnavigate the most historic orb in the universe—the birthplace of humanity: Earth.

Sometimes the difference between reality and insanity is only a matter of absurdity. There is nothing Milo Bishop fears more than the thought that he is going insane. Having grown up hearing his Uncle Jay’s stories about the strange mermaids Milo never had a reason to believe they were actually true. But when a near-death experience gives Milo a vision of a mermaid calling to him for help, Milo is forced to test his uncle’s claims.

Viruses are the world's most abundant life form, and now, when humanity is in the midst of a close encounter with their immense power, perhaps the most feared. But do we understand viruses? Possibly the most enigmatic of living things, they are sometimes not considered a life form at all...

When the alien known as Zava finally finds a sentient world that is worthy of his time and study, many thoughts race through his head. Perhaps a simple survey of the planet would suffice, or maybe a detailed analysis of the sentient civilizations that reside there. He could even conduct an abduction of a few human subjects, all in the name of science and research.

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.

Edward J. Larson is a Pulitzer Prize-winning author and eminent science historian. This marvelously readable, yet sumptuously erudite work traces the development of the scientific theory of evolution. From Darwin's essential trip to the Galápagos, to the most contemporary studies in sociobiology, this work takes listeners both into the field and laboratories of the world's greatest evolutionary scientists, and shows how the theory of evolution has itself evolved.

Few of us know much about the biology of sex determination, but what could be more interesting than to discover how we are shaped into males and females? In this book, Elof Carlson tells the incredible story of the difficult quest to understand how the body forms girls and boys. Carlson's history takes us from antiquity to the present day to detail how each component of human reproduction and sexuality was identified and studied....

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

A sweeping, paradigm-shifting account of how evolution is no longer driven just by nature but also by human choices Why are conditions like autism, asthma, obesity, and allergies exploding at unprecedented rates? Why are we living longer, getting smarter, having far fewer kids? If Darwin was...

Into the Twilight takes place 200 years into the future, when Jacob Ladder and Emma Fine, strangers to one another, wake from two centuries of suspended life to a future that challenges many of their deep-rooted assumptions about what it means to be and remain human. As the story opens, the human race faces demise from within and without. Mulling over its options, the governing council decides that the human genome will require “major redesigning” or “scrapping” if what’s left of humanity is to survive. And that’s where Ike comes in.

In this audiobook, The Human Odyssey, we explore the evolution of those characteristics that make us human. The first section looks at our family tree and why some branches survived and not others. Swings in climate are emerging as a factor in what traits succeeded and failed; meanwhile, DNA analyses show that Homo sapiens interbred with other human species, which played a key role in our survival.

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.

Between what can be learned from evolutionary psychology and cognitive science a picture emerges. In Sex, Murder, and the Meaning of Life, social psychologist Douglas Kenrick fuses these two fields to create a coherent story of human nature. In his analysis, many ingrained, apparently irrational behaviors—one-night stands, prejudice, conspicuous consumption, even art and religious devotion—are quite explicable and (when desired) avoidable.
