Thinking Big How The Evolution Of Social Life Shaped The Human Mind

A closer look at genealogy, incorporating how biological, anthropological, and technical factors can influence human lives We are at a pivotal moment in understanding our remote ancestry and its implications for how we live today. The barriers to what we can know about our distant relatives have been falling as a result of scientific advance, such as decoding the genomes of humans and Neanderthals, and bringing together different perspectives to answer common questions. These collaborations have brought new knowledge and suggested fresh concepts to examine. The results have shaken the old certainties. The results are profound; not just for the study of the past but for appreciating why we conduct our social lives in ways, and at scales, that are familiar to all of us. But such basic familiarity raises a dilemma. When surrounded by the myriad technical and cultural innovations that support our global, urbanized lifestyles we can lose sight of the small social worlds we actually inhabit and that can be traced deep into our ancestry. So why do we need art, religion, music, kinship, myths, and all the other facets of our over-active imaginations if the reality of our effective social worlds is set by a limit of some one hundred and fifty partners (Dunbar’s number) made of family, friends, and useful acquaintances? How could such a social community lead to a city the size of London or a country as large as China? Do we really carry our hominin past into our human present? It is these small worlds, and the link they allow to the study of the past that forms the central point in this book.

A closer look at social history and the growth of the human brain When and how did the brains of our hominin ancestors become human minds? When and why did our capacity for language, art, music and dance evolve? This pathbreaking book proposes that it was the need for early humans to live in ever-larger social groups over greater distances—the ability to “think big”—that drove the enlargement of the human brain and the development of the human mind. This social brain hypothesis, put forward by evolutionary psychologists such as Robin Dunbar, can be tested against archaeological and fossil evidence. The conclusions here—the fruits of over seven years of research—build on the insight that modern humans live in effective social groups of about 150 (so-called “Dunbar’s number”), some three times the size of those of apes and our early ancestors. We live in a world dominated by social networking. Yet our virtual contact lists, whether on Facebook or Twitter, are on average no bigger than Dunbar’s number.

Tested against archaeological evidence, this pathbreaking and provocative book shows we still inhabit social worlds that originated deep in our evolutionary past. Our virtual contact lists, whether on Facebook or Twitter, are on average about 150 - the so-called 'Dunbar's Number' - some three times the size of those of apes and our early ancestors. - When and how did the brains of our hominin ancestors become human minds? - When and why did our capacity for language or art, music and dance evolve? The fruits of over seven years of research, 'Thinking Big' suggests that it was the need for early humans to live in ever-larger social groups that drove the enlargement of the human brain and the development of the human mind.

This volume readdresses the past contribution from archaeology towards the study of evolutionary issues, and ties evolutionary psychology into the extensive historical data from the past, allowing us to escape the confined timeframe of the comparatively recent human mind and explore the question of just what it is that makes us so different.

“Even-handed, up-to-date, and clearly written. . . . If you want to navigate between the Scylla and Charybdis of Neanderthal controversies, you’ll find no better guide.” —Brian Fagan, author of Cro-Magnon In recent years, the common perception of the Neanderthal has been transformed thanks to new discoveries and paradigm-shattering scientific innovations. It turns out that the Neanderthals’ behavior was surprisingly modern: they buried the dead, cared for the sick, hunted large animals in their prime, harvested seafood, and spoke. Meanwhile, advances in DNA technologies have forced a reassessment of the Neanderthals’ place in our own past. For hundreds of thousands of years, Neanderthals evolved in Europe very much in parallel to the Homo sapiens line evolving in Africa, and, when both species made their first forays into Asia, the Neanderthals may even have had the upper hand. Here, Dimitra Papagianni and Michael A. Morse look at the Neanderthals through the full dramatic arc of their existence—from their evolution in Europe to their expansion to Siberia, their subsequent extinction, and ultimately their revival in popular novels, cartoons, cult movies, and TV commercials.

The discovery of ancient stone implements alongside the bones of mammoths by John Evans and Joseph Prestwich in 1859 kicked open the door for a time revolution in human history. Clive Gamble explores the personalities of these revolutionaries and the significant impact their work had on the scientific advances of the next 160 years.

Explains what the mind is, how it evolved, and how it allows us to see, think, feel, laugh, interact, enjoy the arts, and ponder the mysteries of life.

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. Unlike other living animal species, we are born with complicated mechanisms for reasoning about causation, reading the minds of others, copying behaviors, and using language. Cecilia Heyes agrees that adult humans have impressive pieces of cognitive equipment. In her framing, however, these cognitive gadgets are not instincts programmed in the genes but are constructed in the course of childhood through social interaction. Cognitive gadgets are products of cultural evolution, rather than genetic evolution. At birth, the minds of human babies are only subtly different from the minds of newborn chimpanzees. We are friendlier, our attention is drawn to different things, and we have a capacity to learn and remember that outstrips the abilities of newborn chimpanzees. Yet when these subtle differences are exposed to culture-soaked human environments, they have enormous effects. They enable us to upload distinctively human ways of thinking from the social world around us. As Cognitive Gadgets makes clear, from birth our malleable human minds can learn through culture not only what to think but how to think it.
