Cro-Magnons were the first fully modern Europeans—not only the creators of the stunning cave paintings at Lascaux and elsewhere, but the most adaptable and technologically inventive people that had yet lived on earth. The prolonged encounter between the Cro-Magnons and the archaic Neanderthals and between 45,000 and 30,000 years ago was one of the defining moments of history. The Neanderthals survived for some 15,000 years in the face of the newcomers, but were finally pushed aside by the Cro-Magnons’ vastly superior intellectual abilities and cutting-edge technologies, which allowed them to thrive in the intensely challenging climate of the Ice Age.
What do we know about this remarkable takeover? Who were the first modern Europeans and what were they like? How did they manage to thrive in such an extreme environment? And what legacy did they leave behind them after the cold millennia? The age of the Cro-Magnons lasted some 30,000 years—longer than all of recorded history. Cro-Magnon is the story of a little known, yet seminal, chapter of human experience.
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.
Until two million years ago, our ancestors were apelike beings the size of chimpanzees. Then Homo erectus was born and we became human. What caused this extraordinary transformation?
In this stunningly original book, renowned primatologist Richard Wrangham argues that cooking created the human race. At the heart of Catching Fire lies an explosive new idea: The habit of eating cooked rather than raw food permitted the digestive tract to shrink and the human brain to grow, helped structure human society, and created the male-female division of labor. As our ancestors adapted to using fire, humans emerged as “the cooking apes.”
A groundbreaking new theory of evolution, Catching Fire offers a startlingly original argument about how we came to be the social, intelligent, and sexual species we are today.
Somewhere in Africa, more than a million years ago, a line of apes began to rear their young differently than their Great Ape ancestors. From this new form of care came new ways of engaging and understanding each other. How such singular human capacities evolved, and how they have kept us alive for thousands of generations, is the mystery revealed in this bold and wide-ranging new vision of human emotional evolution.
Mothers and Others finds the key in the primatologically unique length of human childhood. If the young were to survive in a world of scarce food, they needed to be cared for, not only by their mothers but also by siblings, aunts, fathers, friends—and, with any luck, grandmothers. Out of this complicated and contingent form of childrearing, Sarah Hrdy argues, came the human capacity for understanding others. Mothers and others teach us who will care, and who will not.
From its opening vision of “apes on a plane”; to descriptions of baby care among marmosets, chimpanzees, wolves, and lions; to explanations about why men in hunter-gatherer societies hunt together (hint: it’s called the Showing-Off Hypothesis), Mothers and Others is compellingly readable. But it is also an intricately knit argument that ever since the Pleistocene, it has taken a village to raise children—and how that gave our ancient ancestors the first push on the path toward becoming emotionally modern human beings.
How language evolved has been called “the hardest problem in science.” In Adam’s Tongue, Derek Bickerton—long a leading authority in this field—shows how and why previous attempts to solve that problem have fallen short. Taking cues from topics as diverse as the foraging strategies of ants, the distribution of large prehistoric herbivores, and the construction of ecological niches, Bickerton produces a dazzling new alternative to the conventional wisdom. Language is unique to humans, but it isn’t the only thing that sets us apart from other species—our cognitive powers are qualitatively different. So could there be two separate discontinuities between humans and the rest of nature? No, says Bickerton; he shows how the mere possession of symbolic units—words—automatically opened a new and different cognitive universe, one that yielded novel innovations ranging from barbed arrowheads to the Apollo spacecraft. Written in Bickerton’s lucid and irreverent style, this book is the first that thoroughly integrates the story of how language evolved with the story of how humans evolved. Sure to be controversial, it will make indispensable reading both for experts in the field and for every reader who has ever wondered how a species as remarkable as ours could have come into existence.
