The Accidental Species
Misunderstandings of Human Evolution
Henry Gee
University of Chicago Press, 2013
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, 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 firsthand experience on the editorial side of many incredible paleontological findings 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.

Apes and Human Evolution
Russell H. Tuttle
Harvard University Press, 2014

In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes—sophisticated but instinctively aggressive and destructive beings.

Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture—speech, mating proscriptions, kinship structures, and moral codes—are symbolic systems that are not manifest in ape niches.

This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.

A Brain for All Seasons
Human Evolution and Abrupt Climate Change
William H. Calvin
University of Chicago Press, 2002
One of the most shocking realizations of all time has slowly been dawning on us: the earth's climate does great flip-flops every few thousand years, and with breathtaking speed. In just a few years, the climate suddenly cools worldwide. With only half the rainfall, severe dust storms whirl across vast areas. Lightning strikes ignite giant forest fires. For most mammals, including our ancestors, populations crash.

Our ancestors lived through hundreds of such abrupt episodes since the more gradual Ice Ages began two and a half million years ago—but abrupt cooling produced a population bottleneck each time, one that eliminated most of their relatives. We are the improbable descendants of those who survived—and later thrived.

William H. Calvin's marvelous A Brain for All Seasons argues that such cycles of cool, crash, and burn powered the pump for the enormous increase in brain size and complexity in human beings. Driven by the imperative to adapt within a generation to "whiplash" climate changes where only grass did well for a while, our ancestors learned to cooperate and innovate in hunting large grazing animals.

Calvin's book is structured as a travelogue that takes us around the globe and back in time. Beginning at Darwin's home in England, Calvin sits under an oak tree and muses on what controls the speed of evolutionary "progress." The Kalahari desert and the Sterkfontein caves in South Africa serve as the backdrop for a discussion of our ancestors' changing diets. A drought-shrunken lake in Kenya shows how grassy mudflats become great magnets for grazing animals. And in Copenhagen, we learn what ice cores have told us about abrupt jumps in past climates.

Perhaps the most dramatic discovery of all, though, awaits us as we fly with Calvin over the Gulf Stream and Greenland: global warming caused by human-made pollution could paradoxically trigger another sudden episode of global cooling. Because of the accumulation of greenhouse gases in the atmosphere, the oceanic "conveyor belt" that sends warmer waters into the North Atlantic could abruptly shut down. If that happens again, much of the Earth could be plunged into a deep chill within a few years. Europe would become as cold and dry as Siberia. Agriculture could not adapt quickly enough to avoid worldwide famines and wars over the dwindling food supplies—a crash from which it would take us many centuries to recover.

With this warning, Calvin connects us directly to evolution and the surprises it holds. Highly illustrated, conversational, and learned, A Brain for All Seasons is a fascinating view of where we came from, and where we're going.

Chimpanzees and Human Evolution
Martin N. Muller
Harvard University Press, 2017

Knowledge of chimpanzees in the wild has expanded dramatically in recent years. This comprehensive volume, edited by Martin Muller, Richard Wrangham, and David Pilbeam, brings together scientists who are leading a revolution to discover and explain what is unique about humans, by studying their closest living relatives. Their observations and conclusions have the potential to transform our understanding of human evolution.

Chimpanzees offer scientists an unmatched view of what distinguishes humanity from its apelike ancestors. Based on evidence from the hominin fossil record and extensive morphological, developmental, and genetic data, Chimpanzees and Human Evolution makes the case that the last common ancestor of chimpanzees and humans was chimpanzee-like. It most likely lived in African rainforests around eight million years ago, eating fruit and walking on its knuckles. Readers will learn why chimpanzees are a better model for the last common ancestor than bonobos, gorillas, or orangutans. A thorough chapter-by-chapter analysis reveals which key traits we share with chimpanzees and which appear to be distinctive to Homo sapiens, and shows how understanding chimpanzees helps us account for the evolution of human uniqueness. Traits surveyed include social behaviors and structures, mating systems, diet, hunting practices, tool use, culture, cognition, and communication.

Edited by three of primatology’s most renowned experts, with contributions from 32 scholars drawing on decades of field research, Chimpanzees and Human Evolution provides readers with detailed up-to-date information on what we can infer about our chimpanzee-like ancestors and points the way forward for the next generation of discoveries.

Culture and the Course of Human Evolution
Gary Tomlinson
University of Chicago Press, 2018
The rapid evolutionary development of modern Homo sapiens over the past 200,000 years is a topic of fevered interest in numerous disciplines. How did humans, while undergoing few physical changes from their first arrival, so quickly develop the capacities to transform their world? Gary Tomlinson’s Culture and the Course of Human Evolution is aimed at both scientists and humanists, and it makes the case that neither side alone can answer the most important questions about our origins.
 
Tomlinson offers a new model for understanding this period in our emergence, one based on analysis of advancing human cultures in an evolution that was simultaneously cultural and biological—a biocultural evolution. He places front and center the emergence of culture and the human capacities to create it, in a fashion that expands the conceptual framework of recent evolutionary theory. His wide-ranging vision encompasses arguments on the development of music, modern technology, and metaphysics. At the heart of these developments, he shows, are transformations in our species’ particular knack for signmaking. With its innovative synthesis of humanistic and scientific ideas, this book will be an essential text.

The Dominant Animal
Human Evolution and the Environment
Paul R. Ehrlich and Anne H. Ehrlich
Island Press, 2008
In humanity’s more than 100,000 year history, we have evolved from vulnerable creatures clawing sustenance from Earth to a sophisticated global society manipulating every inch of it. In short, we have become the dominant animal. Why, then, are we creating a world that threatens our own species? What can we do to change the current trajectory toward more climate change, increased famine, and epidemic disease?
 
Renowned Stanford scientists Paul R. Ehrlich and Anne H. Ehrlich believe that intelligently addressing those questions depends on a clear understanding of how we evolved and how and why we’re changing the planet in ways that darken our descendants’ future. The Dominant Animal arms readers with that knowledge, tracing the interplay between environmental change and genetic and cultural evolution since the dawn of humanity. In lucid and engaging prose, they describe how Homo sapiens adapted to their surroundings, eventually developing the vibrant cultures, vast scientific knowledge, and technological wizardry we know today.
 
But the Ehrlichs also explore the flip side of this triumphant story of innovation and conquest. As we clear forests to raise crops and build cities, lace the continents with highways, and create chemicals never before seen in nature, we may be undermining our own supremacy. The threats of environmental damage are clear from the daily headlines, but the outcome is far from destined. Humanity can again adapt—if we learn from our evolutionary past.
 
Those lessons are crystallized in The Dominant Animal. Tackling the fundamental challenge of the human predicament, Paul and Anne Ehrlich offer a vivid and unique exploration of our origins, our evolution, and our future.

Human Evolution and Development
Nico M. van Straalen Dick Roelofs
Amsterdam University Press, 2019
Our understanding of human evolution is proceeding at an unprecedented rate over the last years due to spectacular fossil finds, reconstructions based on genome comparison, ancient DNA sequencing and new insights into developmental genetics. This book takes an integrative approach in which the development of the human embryo, the evolutionary history of our body, the structure of human populations, their dispersal over the world and their cultures are examined by integrating paleoanthropology, developmental biology, comparative zoology, population genetics and phylogenetic reconstruction.
The authors discuss questions like: - What do we know about ancient humans? - What happens in the development of an embryo? - How did we manage to walk upright and why did we lose our hair? - What is the relationship between language, migration and evolution? - How does our body respond to the challenges of modern society?
In addition to being a core text for the study of the life sciences, Human Evolution and Development is an easy-to-read overview for the interested layperson.

Java Man
How Two Geologists Changed Our Understanding of Human Evolution
Carl C. Swisher III, Garniss H. Curtis, and Roger Lewin
University of Chicago Press, 2001
"'Garniss, lend me your knife for a second, will you,' I whispered." So begins Java Man, the inside story of how one discovery—a human skull found on the island of Java—by two geologists shook the foundations of science. By uncovering new evidence about the hominid known as Java man, Carl C. Swisher and Garniss H. Curtis were able to date his fossil remains at 1.7 million years, an age that stunned the scientific community because it pushed back the time when humans migrating out of Africa first reached Eurasia by nearly one million years. Cowritten by the popular science writer Roger Lewin, this is a gripping and informative account of the discovery that breathed new life into the human origins debate.

Kinship to Mastery
Biophilia In Human Evolution And Development
Stephen R. Kellert
Island Press, 1997

Kinship to Mastery is a fascinating and accessible exploration of the notion of biophilia -- the idea that humans, having evolved with the rest of creation, possess a biologically based attraction to nature and exhibit an innate affinity for life and lifelike processes. Stephen R. Kellert sets forth the idea that people exhibit different expressions of biophilia in different contexts, and demonstrates how our quality of life in the largest sense is dependent upon the richness of our connections with nature.

While the natural world provides us with material necessities -- food, clothing, medicine, clean air, pure water -- it just as importantly plays a key role in other aspects of our lives, including intellectual capacity, emotional bonding, aesthetic attraction, creativity, imagination, and even the recognition of a just and purposeful existence. As Kellert explains, each expression of biophilia shows how our physical, material, intellectual, emotional, and spiritual well-being is to a great extent dependent on our relationships with the natural world that surrounds us.

Kinship to Mastery is a thought-provoking examination of a concept that, while not widely known, has a significant and direct effect on the lives of people everywhere. Because the full expression of biophilia is integral to our overall health, our ongoing destruction of the environment could have far more serious consequences than many people think. In a readable and compelling style, Kellert describes and explains the concept of biophilia, and demonstrates to a general audience the wide-ranging implications of environmental degradation.

Kinship to Mastery continues the exploration of biophilia begun with Edward O. Wilson's landmark book Biophilia (Harvard University Press, 1984) and followed by The Biophilia Hypothesis (Island Press, 1993), co-edited by Wilson and Kellert, which brought together some of the most creative scientists of our time to explore Wilson's theory in depth.

The Lives of the Brain
Human Evolution and the Organ of Mind
John S. Allen
Harvard University Press, 2009

Though we have other distinguishing characteristics (walking on two legs, for instance, and relative hairlessness), the brain and the behavior it produces are what truly set us apart from the other apes and primates. And how this three-pound organ composed of water, fat, and protein turned a mammal species into the dominant animal on earth today is the story John S. Allen seeks to tell.

Adopting what he calls a “bottom-up” approach to the evolution of human behavior, Allen considers the brain as a biological organ; a collection of genes, cells, and tissues that grows, eats, and ages, and is subject to the direct effects of natural selection and the phylogenetic constraints of its ancestry. An exploration of the evolution of this critical organ based on recent work in paleo­anthropology, brain anatomy and neuroimaging, molecular genetics, life history theory, and related fields, his book shows us the brain as a product of the contexts in which it evolved: phylogenetic, somatic, genetic, ecological, demographic, and ultimately, cultural-linguistic. Throughout, Allen focuses on the foundations of brain evolution rather than the evolution of behavior or cognition. This perspective demonstrates how, just as some aspects of our behavior emerge in unexpected ways from the development of certain cognitive capacities, a more nuanced understanding of behavioral evolution might develop from a clearer picture of brain evolution.

Lucy’s Legacy
Sex and Intelligence in Human Evolution
Alison Jolly
Harvard University Press, 1999

Alison Jolly believes that biologists have an important story to tell about being human—not the all-too-familiar tale of selfishness, competition, and biology as destiny but rather one of cooperation and interdependence, from the first merging of molecules to the rise of a species inextricably linked by language, culture, and group living. This is the story that unfolds in Lucy’s Legacy, the saga of human evolution as told by a world-renowned primatologist who works among the female-dominant ringtailed lemurs of Madagascar.

We cannot be certain that Lucy was female—the bones themselves do not tell us. However, we do know, as Jolly points out in this erudite, funny, and informative book, that the females who came after Lucy—more adept than their males in verbal facility, sharing food, forging links between generations, migrating among places and groups, and devising creative mating strategies—played as crucial a role in the human evolutionary process as “man” ever did. In a book that takes us from the first cell to global society, Jolly shows us that to learn where we came from and where we go next, we need to understand how sex and intelligence, cooperation and love, emerged from the harsh Darwinian struggle in the past, and how these natural powers may continue to evolve in the future.

Religion in Human Evolution
From the Paleolithic to the Axial Age
Robert N. Bellah
Harvard University Press, 2011

A New York Times Book Review Editors’ Choice
An ABC Australia Best Book on Religion and Ethics of the Year
Distinguished Book Award, Sociology of Religion Section of the American Sociological Association

Religion in Human Evolution is a work of extraordinary ambition—a wide-ranging, nuanced probing of our biological past to discover the kinds of lives that human beings have most often imagined were worth living. It offers what is frequently seen as a forbidden theory of the origin of religion that goes deep into evolution, especially but not exclusively cultural evolution.

“Of Bellah’s brilliance there can be no doubt. The sheer amount this man knows about religion is otherworldly…Bellah stands in the tradition of such stalwarts of the sociological imagination as Emile Durkheim and Max Weber. Only one word is appropriate to characterize this book’s subject as well as its substance, and that is ‘magisterial.’”
—Alan Wolfe, New York Times Book Review

Religion in Human Evolution is a magnum opus founded on careful research and immersed in the ‘reflective judgment’ of one of our best thinkers and writers.”
—Richard L. Wood, Commonweal

The Riddled Chain
Chance, Coincidence and Chaos in Human Evolution
McKee, Jeffrey Kevin
Rutgers University Press, 2000

Did human evolution proceed in an inevitable fashion? Can we attribute our origins solely to natural selection, or were more mischievous forces at work?

These are the questions investigated by anthropologist Jeff McKee. He argues that if we were to wind back the clock to our split from ancestral apes, evolution would proceed differently. Ever since our ancestors first stood up on two feet, natural selection undoubtedly was an important factor in guiding human evolution. But McKee shakes the standard notion that natural selection steered early hominids toward particular environmental adaptations. The fossil remains of our ancestors reveal a different story one of an adaptable hominid with no particular direction. It becomes clear that the evolutionary road to Homo sapiens was not paved solely by natural selection; indeed, there was no road to follow. There was just a dim path cut out by prehistoric coincidences and contingencies. Had any link in the evolutionary chain of events been slightly different, then our species would not be as it is today . . . or our ancestors may not have survived at all. 

With equal doses of humor and awe, McKee illustrates how the chain of evolution has been riddled by chance, coincidence, and chaos. He uses familiar examples, noting that many of us exist as individuals because of chance meetings of our parents. From the present back through prehistory, chance is at the heart of our creation is chaos. The classic example of chaos is the butterfly effect: a single butterfly, flapping its wings, causes a tiny change in the atmosphere, which in turn amplifies to affect the course of storms on another continent. McKee ties such examples of unpredictability to fossil evidence and computer simulations, revealing the natural coincidences that shaped our evolution. Although chaos exacted an evolutionary price by limiting the powers of natural selection, it also made us what we are. One can only conclude that human beings were neither inevitable nor probable.
