Human Genetics

The idea of a missing link between humanity and our animal ancestors predates evolution and popular science and actually has religious roots in the deist concept of the Great Chain of Being. Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being "animal" and started being "human". In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion.

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.

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.

As biologist Jeremy Griffith explains in The Interview (which psychiatrist Professor Harry Prosen described as the most important interview of all time), while we humans lacked the explanation for our 2-million-year corrupted human condition we had no choice but to deny that our distant ape ancestors lived in a state of cooperative and loving innocence.

A spirited collection of essays by cutting-edge neuroscientists that irreverently explores the quirky and counter intuitive aspects of brain function. Neuroscientist David J. Linden approached leading brain researchers and asked each the same question: "What idea about brain function would you most like to explain to the world?" Their responses make up this one-of-a-kind collection of popular science essays that seeks to expand our knowledge of the human mind and its possibilities.

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.

The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

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.

We've all asked ourselves the question. It's impossible to look up at the stars and NOT think about it: Are we alone in the universe? Books, movies, and television shows proliferate that attempt to answer this question and explore it. In Out There, Space.com senior writer Dr. Michael Wall treats that question as merely the beginning, touching off a wild ride of exploration into the final frontier. He considers, for instance, the myriad of questions that would arise once we do discover life beyond Earth (an eventuality which, top NASA officials told Wall, is only drawing closer).

Hundreds of years in the future our civilization is shrunk down but we go on. There is advanced technology, there are robots. And there are clones. E. A. Smithe is a borrowed person, his personality an uploaded recording of a deceased mystery writer. Smithe is a piece of property, not a legal human. As such, Smithe can be loaned to other branches. Which he is. Along with two fellow reclones, a cookbook and romance writer, they are shipped to Polly's Cove, where Smithe meets a little girl who wants to save her mother, a father who is dead but perhaps not.

Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution.

In 1997, Yiannis Kouros ran 188 miles in 24 hours. In 1984, at age 42, Maria Moreira gave birth to her 10th set of twins. In 1973, Terry Tao learned to read when he was two years old. Tao started college at age nine, and at 24 was appointed a full-time professor at UCLA. What does it feel like to be exceptional? And what does it take to get there? Why can some people achieve greatness when others can’t, no matter how hard they try? Just how much potential does our species have? Evolutionary biologist Rowan Hooper has the answers.

AD 2107: A generation ago, Earth and the cislunar colonies banned genetic and cybernetic modifications. But out in the Asteroid Belt, anything goes. Dozens of flourishing space habitats are spawning exotic new societies and strange new varieties of humans. It’s a volatile situation that threatens the peace and stability of the entire solar system.

Pets have never been more popular. Over half of American households share their home with either a cat or a dog, and many contain both. This is a huge change from only a century ago, when the majority of domestic cats and dogs were working animals, keeping rodents at bay, guarding property, herding sheep. Nowadays, most are valued solely for the companionship they provide. As mankind becomes progressively more urban and detached from nature, we seem to be clinging to the animals that served us well in the past.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

The emerging field of evolutionary psychology remains controversial, perhaps especially among Christians. Yet according to Justin Barrett and Pamela Ebstyne King, it can be a powerful tool for understanding human nature and our distinctively human purpose. Thriving with Stone Age Minds provides an introduction to evolutionary psychology, explaining key concepts like hyper-sociality, information gathering, and self-control.

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.

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.

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.

In this fascinating exploration, geneticist Bryan Sykes turns his sights on the United States, one of the most genetically variegated countries in the world. From the blue-blooded pockets of old-WASP New England to the vast tribal lands of the Navajo, Bryan Sykes takes us on a historical genetic tour, interviewing genealogists, geneticists, anthropologists, and everyday Americans with compelling ancestral stories.
