Our prehistoric forebears are often portrayed as spear-wielding savages, but the earliest human societies are likely to have been founded on enlightened egalitarian principles, according to scientists.

A study has shown that in contemporary hunter-gatherer tribes, men and women tend to have equal influence on where their group lives and who they live with. The findings challenge the idea that sexual equality is a recent invention, suggesting that it has been the norm for humans for most of our evolutionary history.

Mark Dyble, an anthropologist who led the study at University College London, said: “There is still this wider perception that hunter-gatherers are more macho or male-dominated. We’d argue it was only with the emergence of agriculture, when people could start to accumulate resources, that inequality emerged.”

Dyble says the latest findings suggest that equality between the sexes may have been a survival advantage and played an important role in shaping human society and evolution. “Sexual equality is one of a important suite of changes to social organisation, including things like pair-bonding, our big, social brains, and language, that distinguishes humans,” he said. “It’s an important one that hasn’t really been highlighted before.” Link

Of the many myths told about American slavery, one of the biggest is that it was an archaic practice that only enriched a small number of men.

The argument has often been used to diminish the scale of slavery, reducing it to a crime committed by a few Southern planters, one that did not touch the rest of the United States. Slavery, the argument goes, was an inefficient system, and the labor of the enslaved was considered less productive than that of a free worker being paid a wage. The use of enslaved labor has been presented as premodern, a practice that had no ties to the capitalism that allowed America to become — and remain — a leading global economy.

But as with so many stories about slavery, this is untrue. Slavery, particularly the cotton slavery that existed from the end of the 18th century to the beginning of the Civil War, was a thoroughly modern business, one that was continuously changing to maximize profits.

To grow the cotton that would clothe the world and fuel global industrialization, thousands of young enslaved men and women — the children of stolen ancestors legally treated as property — were transported from Maryland and Virginia hundreds of miles south, and forcibly retrained to become America’s most efficient laborers. As they were pushed into the expanding territories of Mississippi and Louisiana, sold and bid on at auctions, and resettled onto forced labor camps, they were given a task: to plant and pick thousands of pounds of cotton.

Hunter-gatherers, for example, tend to believe that all objects – whether animal, vegetable or mineral – have supernatural aspects (animism) and that the world is imbued with supernatural forces (animatism). These must be understood and respected; human morality generally doesn’t figure significantly. This worldview makes sense for groups too small to need abstract codes of conduct, but who must know their environment intimately. (An exception: Shinto, an ancient animist religion, is still widely practised in hyper-modern Japan.)

At the other end of the spectrum, the teeming societies of the West are at least nominally faithful to religions in which a single watchful, all-powerful god lays down, and sometimes enforces, moral instructions: Yahweh, Christ and Allah. The psychologist Ara Norenzayan argues it was belief in these “Big Gods” that allowed the formation of societies made up of large numbers of strangers. Whether that belief constitutes cause or effect has recently been disputed, but the upshot is that sharing a faith allows people to co-exist (relatively) peacefully. The knowledge that Big God is watching makes sure we behave ourselves. Link
