The Accidental Homo Sapiens

What happens now that human population has outpaced biological natural selection? Two leading scientists reveal how we became who we are—and what we might become. When we think of evolution, the image that likely comes to mind is the iconic, straight-forward image of a primate morphing into a human being. Yet random events have played huge roles in determining the evolutionary histories of everything from lobsters to humans. However, random genetic novelties are most likely to "stick" in small populations. It is mathematically unlikely to happen in large ones. With our enormous and seemingly inexorably expanding population, humanity has fallen under the influence of the famous (or infamous) “bell curve.” This revelatory new book explores what the future of our species could hold, while simultaneously revealing what we didn’t become—and what we won’t become. A cognitively unique species, our actions fall on a bell curve as well. Individuals may be saintly or evil, narrow-minded or visionary. But it is possible not just for the species, but for a person to be all of these things—even in a single day. We all fall somewhere within the giant hyperspace of the human condition that these curves describe. The Accidental Homo Sapiens shows readers that though humanity now exists on this bell curve, we are far from a stagnant species. Tattersall and DeSalle reveal how biological evolution in modern humans has given way to a cultural dynamic that is unlike anything else the Earth has ever witnessed, and that will keep life interesting—perhaps sometimes too interesting—for as long as we exist on this planet.

The last man standing? Earth is in crisis. And the intergalactic managers who oversee all creatures of the Milky Way Galaxy are tasked to bottom-line man's usefulness. Should they let homo sapiens survive or watch them continue to their own destruction? To answer that, the extraterrestrials charged with evaluating us as a species discover incredible truths about who we are - the good, the bad, the really, really bizarre. They look at how we govern and decide to change the rules. The Accidental President takes a deep dive into our politics and human nature based on hard-to-believe but historically accurate facts. Take a fresh look at the two-legged creatures who dominate the third planet from the Sun, and follow the extraterrestrials as they tally our vices and virtues to reach a final judgment. Or do they? The Accidental President, I. Michael Grossman's seventh book, is raw satire. You may laugh, even cheer at his take on humanity, or consider him outrageous. But you'll find yourself rolling your eyes about curious creatures known as humankind.

“With a delightfully irascible sense of humor, Henry Gee reflects on our origin . . . an excellent primer on how—and how not—to think about human evolution.” —Carl Zimmer, author of Parasite Rex 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, arguing that it reflects a profound misunderstanding of how evolution works and, when applied to the evolution of our own species, supports mistaken ideas about our own place in the universe. Gee presents a robust and stark challenge to our tendency to see ourselves as the acme of creation. Far from being a quirk of religious fundamentalism, human exceptionalism, Gee argues, is an error that also infects scientific thought. Touring the many features of human beings that have recurrently been used to distinguish us from the rest of the animal world, Gee shows that our evolutionary outcome is one possibility among many, one that owes more to chance than to an organized progression to supremacy. He starts with bipedality, which he shows could have arisen entirely by accident, as a by-product of sexual selection, then moves on to technology, large brain size, intelligence, language, and, finally, sentience. He reveals each of these attributes to be alive and well throughout the animal world—they are not, indeed, unique to our species. The Accidental Species combines Gee’s expertise and experience with healthy skepticism and humor to create a book that aims to overturn popular thinking on human evolution. The key is not what’s missing—but how we’re linked.

Your author decided to write this book about Human Evolution after seeing a Science Program about Evolution on KCET, the Public Service TV Station in the Los Angeles area. I was impressed with the amount of research going on in this area trying to find out where we, Homosapiens, came from. I decided to use the Google and Yahoo search engines to find out the latest probes which I used for this book. I have included the many reference sources so the reader can visit these Internet accounts to keep up with what is happening after this book is published. In other words, this is a snapshot-in-time report of what is happening research-wise at the end of the first decade of the 21st Century.

“Rutherford describes [The Book of Humans] as being about the paradox of how our evolutionary journey turned ‘an otherwise average ape’ into one capable of creating complex tools, art, music, science, and engineering. It’s an intriguing question, one his book sets against descriptions of the infinitely amusing strategies and antics of a dizzying array of animals.”—The New York Times Book Review Publisher’s Note: The Book of Humans was previously published in hardcover as Humanimal. In this new evolutionary history, geneticist Adam Rutherford explores the profound paradox of the human animal. Looking for answers across the animal kingdom, he finds that many things once considered exclusively human are not: We aren’t the only species that “speaks,” makes tools, or has sex outside of procreation. Seeing as our genome is 98 percent identical to a chimpanzee’s, our DNA doesn’t set us far apart, either. How, then, did we develop the most complex culture ever observed? The Book of Humans proves that we are animals indeed—and reveals how we truly are extraordinary.

Why aren’t we more like other apes? How did we win the evolutionary race? Find out how “wise” Homo sapiens really are. Prehistory has never been more exciting: New discoveries are overturning long-held theories left and right. Stone tools in Australia date back 65,000 years—a time when, we once thought, the first Sapiens had barely left Africa. DNA sequencing has unearthed a new hominid group—the Denisovans—and confirmed that crossbreeding with them (and Neanderthals) made Homo sapiens who we are today. A Pocket History of Human Evolution brings us up-to-date on the exploits of all our ancient relatives. Paleoanthropologist Silvana Condemi and science journalist François Savatier consider what accelerated our evolution: Was it tools, our “large” brains, language, empathy, or something else entirely? And why are we the sole survivors among many early bipedal humans? Their conclusions reveal the various ways ancient humans live on today—from gossip as modern “grooming” to our gendered division of labor—and what the future might hold for our strange and unique species.
