Laura Betzig studies history as natural history. She's done fieldwork in the Caroline Islands; looked at the cross-cultural record; and read ancient, medieval and modern history. She's written over a hundred scientific and scholarly articles on subjects from sex in the Old Testament, to the persecution of Christians, to the causes of the English Revolution; she's published 3 books; and she's spent the last couple of decades at work on The Badge of Lost Innocence, a history of the West.

Why is equality rare in history? 

It's rare in natural history too, and that�s a good clue. Whenever animals get together, they play by the same rules. Stronger animals take more than their share; weaker animals take less. Winners relax, are well fed, and breed. Losers work harder, eat less, and don�t get as much sex. Sometimes the differences are small. Other times, they�re not. Just short of 28 years after he boarded HMS Beagle and set sail around the world, Darwin ended The Origin of Species with a prophecy: �Much light will be thrown on the origin of man and his history.� Betzig asks: How much light?

She started her career on Ifaluk Atoll, a 6-square kilometer ring of coral 7� north of the equator in a Micronesian archipelago. Where she discovered that, compared to the families of commoners, chiefs' families were better off. When fish were redistributed after island-wide catches, chiefs went home with more than their share; when taro and other staples were traded on a daily basis, their households took in more than they gave out; they were able to spend more time with their daughters and sons; they adopted out more of their children than they adopted in. And they were able to raise bigger families as a result.

Betzig followed up with a comparative study of 106 politically autonomous societies drawn from the Standard Cross Cultural Sample. Where it became obvious that, on every continent, political power maps onto sexual access in an almost linear way. In societies without hierarchies, most men make do with one woman at a time. At the edge of the Serengeti and in the forests of Paraguay, the best Hadza and Ach� hunters father around 10 sons and daughters. Big men, on the other hand, often have dozens of women. A Yanomam� headman on the Orinoco River Basin was the progenitor of 231 grandchildren by 43 children; and in settlements all along the salmon-rich Northwest Coast, chiefs supported as many as 10 wives, with dozens of captive slaves. And emperors have had access to hundreds or thousands of women. The Sui Dynasty emperor Yangdi, who built the Grand Canal and rebuilt the Great Wall, kept an inner palace retinue of 100,000; and on statues and scarabs and ostraca and in the tomb of the 19th-dynasty pharaoh Rameses II, the names of more than 50 sons�generals, hereditary counts, chiefs of secrets, scribes�survive from his 66-year reign.

Over the last couple of decades, Betzig has looked at the historical record. Where she's found that, over the last few centuries, political and reproductive privileges declined at the same time. Under the Roman Empire, knights and senators were punished for sexual excesses; but Roman emperors like Augustus had access to wives, to the concubines who occupied their palace apartments, and to hundreds or thousands of slaves. Even under the Roman Church, dukes with iniquitous morals got locked up in monasteries for life; but kings like Charlemagne had sexual access to spouses, to the trollops who lived in their castles, and to the well-secured and well-provided-for serfs who worked on their estates. But as the millennium turned, things changed. After king John conceded Magna Carta in 1215, his son Henry III summoned knights and citizens to Westminster, where taxes were granted and petitions were heard. Subsequent parliaments had Edward II, Richard II and Henry VI deposed: they were "incorrigible and without hope of amendment;" or "women had been violated and raped;" or "the ravishing and defiling of religious women, maidens, widows and men's wives" had gone on. Then on a cold day in 1649, "for the advancement and upholding of the personal interest of will, power, and pretended prerogative to himself and his family, against the public interest, common right, liberty, justice, and peace of the people of this nation," a High Court of Justice had the head of Charles I cut off. Which raises another question.

What makes societies more or less fair? 

Why do winners take all in some groups, and why do winners in other groups take less? Because, as Darwin pointed out in The Descent of Man, mobility makes hierarchies topple. �Nomadic habits, whether over wide plains, or through the dense forests of the tropics, or along the shores of the sea, have in every case been highly detrimental.� Animals tend to form groups where resources are clumped, or where they're hemmed in by obstacles to flight. And as the costs of leaving a society increase, monarchies rise up. That's true of social insects, fish, birds and mammals. And as it turns out, it's true of us.

For hundreds of thousands of years, most of us made a living by moving around. We followed the migrations of game animals, and the windfalls of natural harvests; we wandered in search of water, and from shelter to shelter. And whenever the food and water were gone, we moved on.

Then over the last few thousand years, we started to settle down. On land between the Tigris and Euphrates, bordered to the east by the Zagros Mountains and by the Syrian Desert to the west, the Akkadian empire began. Egypt became an empire on the black land of the Nile, bounded by the red land of deserts that stretched east and west. Empires on the Indus and Ganges were hemmed in by the Himalayas, or Abodes of Snow, and by the Hindu Killers, or Kush. And on the territory of Qin, surrounded by mountains and girdled by the Yellow River, the first emperor of China rose up.

When those barriers opened up, empires were lost. After pope Urban II preached at Clermont in the fall of 1095, caravans of crusaders headed east toward the Levant. They settled down with Syrian, Armenian or Saracen women at Edessa, Antioch, Tripoli or Jerusalem; they supported children and grandchildren of their own. Then after Columbus set sail in the fall of 1492, caravels of colonists headed west across the Atlantic. They went in pursuit of happiness; they were looking for the blessings of liberty, for themselves and their Posterity.

Laura Betzig got a Ph.D. in anthropology at Northwestern University; she�s held research and teaching positions at Northwestern, the University of California, and the University of Michigan Museum of Natural History. She�s lectured all over the US and Europe in departments of biology, anthropology, history, economics, philosophy, political science, psychology and religion; at interdisciplinary conferences; and to general audiences. She's done interviews for ABC World News Tonight, the History Channel, the Discovery Channel, the Learning Channel, the CBC, Britain�s Channel 4, KRO TV in the Netherlands, Netflix, iTunes and Amazon Prime. She blogs on �The Political Animal� for Psychology Today; she�s answered the Annual Question at Edge; and her work has been written up in newspapers and magazines like Time, The London Times, The New York Times, The Washington Post, New Scientist, Smithsonian, Discover, Worth, The Economist, The Atlantic, Politico, Slate, The Huffington Post, BBC Future and US News & World Report.

Laura's daughter Alexa, MIT '07, Harvard '11, assesses targeted cancer therapies for a biotech in Cambridge; her son Max, Carnegie Mellon '11, Booth '22, who led his soccer team to consecutive NCAA tournament berths, works in Chicago in finance. Many of their ancestors were self-made.  Laura's father, who invented machine tools, founded a company at 60; her brother Eric, who invents microscopes, won a Nobel Prize for Chemistry in 2014. Laura and her husband, the pediatrician Paul Turke, live together near their grandchildren, on Strawberry Lake.
