What happened to the others? And what may happen to us?
There are three reasons why I think this book is worth reading:

My Book Highlights:
"... You could never convince a monkey to give you a banana by promising him limitless bananas after death in monkey heaven..."
"... How do you cause people to believe in an imagined order such as Christianity, democracy or capitalism? First, you never admit that the order is imagined..."
"... Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behaviour, one that goes against the laws of nature, simply cannot exist, so it would need no prohibition..."
"... One of history’s few iron laws is that luxuries tend to become necessities and to spawn new obligations..."
"... How many young college graduates have taken demanding jobs in high-powered firms, vowing that they will work hard to earn money that will enable them to retire and pursue their real interests when they are thirty-five? But by the time they reach that age, they have large mortgages, children to school, houses in the suburbs that necessitate at least two cars per family, and a sense that life is not worth living without really good wine and expensive holidays abroad. What are they supposed to do, go back to digging up roots? No, they double their efforts and keep slaving away..."
"... Consistency is the playground of dull minds..."
"... Biology enables, culture forbids..."
"... We did not domesticate wheat. It domesticated us..."
"... The romantic contrast between modern industry that “destroys nature” and our ancestors who “lived in harmony with nature” is groundless. Long before the Industrial Revolution, Homo sapiens held the record among all organisms for driving the most plant and animal species to their extinctions. We have the dubious distinction of being the deadliest species in the annals of life..."
"... Money is the most universal and most efficient system of mutual trust ever devised..."
"... This is the essence of the Agricultural Revolution: the ability to keep more people alive under worse conditions..."
"... Happiness does not really depend on objective conditions of either wealth, health or even community. Rather, it depends on the correlation between objective conditions and subjective expectations..."
"... Nothing captures the biological argument better than the famous New Age slogan: ‘Happiness begins within.’ Money, social status, plastic surgery, beautiful houses, powerful positions – none of these will bring you happiness. Lasting happiness comes only from serotonin, dopamine and oxytocin..."
"... Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behavior, one that goes against the laws of nature, simply cannot exist..."
"... Large numbers of strangers can cooperate successfully by believing in common myths. Any large-scale human cooperation – whether a modern state, a medieval church, an ancient city or an archaic tribe – is rooted in common myths that exist only in people’s collective imagination..."
"... Each year the US population spends more money on diets than the amount needed to feed all the hungry people in the rest of the world..."
"... Evolution has made Homo sapiens, like other social mammals, a xenophobic creature. Sapiens instinctively divide humanity into two parts, ‘we’ and ‘they’..."
"... In order to change an existing imagined order, we must first believe in an alternative imagined order..."
"... Hierarchies serve an important function. They enable complete strangers to know how to treat one another without wasting the time and energy needed to become personally acquainted..."
"... Domesticated chickens and cattle may well be an evolutionary success story, but they are also among the most miserable creatures that ever lived. The domestication of animals was founded on a series of brutal practices that only became crueler with the passing of the centuries..."
"... The Agricultural Revolution certainly enlarged the sum total of food at the disposal of humankind, but the extra food did not translate into a better diet or more leisure. Rather, it translated into population explosions and pampered elites. The average farmer worked harder than the average forager and got a worse diet in return. The Agricultural Revolution was history’s biggest fraud.2 Who was responsible? Neither kings, nor priests, nor merchants. The culprits were a handful of plant species, including wheat, rice, and potatoes. These plants domesticated Homo sapiens, rather than vice versa..."
"... Our language evolved as a way of gossiping..."
"... Our DNA still thinks we are in the Savannah..."
"... In contrast, humankind ascended to the top so quickly that the ecosystem was not given time to adjust. Moreover, humans themselves failed to adjust. Most top predators of the planet are majestic creatures. Millions of years of dominion have filled them with self-confidence. Sapiens by contrast is more like a banana republic dictator. Having so recently been one of the underdogs of the savannah, we are full of fears and anxieties over our position, which makes us doubly cruel and dangerous. Many historical calamities, from deadly wars to ecological catastrophes, have resulted from this over-hasty jump..."
"... When agriculture and industry came along people could increasingly rely on the skills of others for survival, and new ‘niches for imbeciles’ were opened up. You could survive and pass your unremarkable genes to the next generation by working as a water carrier or an assembly-line worker..."
"... Our lack of brothers and sisters makes it easier to imagine that we are the epitome of creation and that a chasm separates us from the rest of the animal kingdom. When Charles Darwin indicated that Homo sapiens was just another kind of animal, people were outraged. Even today many refuse to believe it. Had the Neanderthals survived, would we still imagine ourselves to be a creature apart? Perhaps this is exactly why our ancestors wiped out the Neanderthals. They were too familiar to ignore, but too different to tolerate..."
