In America during the 1970s, mothers maintained skin-to-skin contact with babies as little as 16 percent of the time, which is a level that traditional societies would probably consider a form of child abuse. Also unthinkable would be the modern practice of making young children sleep by themselves. In two American studies of middle-class families during the 1980s, 85 percent of young children slept alone in their own room—a figure that rose to 95 percent among families considered “well educated.” Northern European societies, including America, are the only ones in history to make very young children sleep alone in such numbers. The isolation is thought to make many children bond intensely with stuffed animals for reassurance. Only in Northern European societies do children go through the well-known developmental stage of bonding with stuffed animals; elsewhere, children get their sense of safety from the adults sleeping near them.
The point of making children sleep alone, according to Western psychologists, is to make them “self-soothing,” but that clearly runs contrary to our evolution. Humans are primates—we share 98 percent of our DNA with chimpanzees—and primates almost never leave infants unattended, because they would be extremely vulnerable to predators. Infants seem to know this instinctively, so being left alone in a dark room is terrifying to them. Compare the self-soothing approach to that of a traditional Mayan community in Guatemala: “Infants and children simply fall asleep when sleepy, do not wear specific sleep clothes or use traditional transitional objects, room share and cosleep with parents or siblings, and nurse on demand during the night.” Another study notes about Bali: “Babies are encouraged to acquire quickly the capacity to sleep under any circumstances, including situations of high stimulation, musical performances, and other noisy observances which reflect their more complete integration into adult social activities.”
As modern society reduced the role of community, it simultaneously elevated the role of authority. The two are uneasy companions, and as one goes up, the other tends to go down. In 2007, anthropologist Christopher Boehm published an analysis of 154 foraging societies that were deemed to be representative of our ancestral past, and one of their most common traits was the absence of major wealth disparities between individuals. Another was the absence of arbitrary authority. “Social life is politically egalitarian in that there is always a low tolerance by a group’s mature males for one of their number dominating, bossing, or denigrating the others,” Boehm observed. “The human conscience evolved in the Middle to Late Pleistocene as a result of… the hunting of large game. This required… cooperative band-level sharing of meat.”
Because tribal foragers are highly mobile and can easily shift between different communities, authority is almost impossible to impose on the unwilling. And even without that option, males who try to take control of the group—or of the food supply—are often countered by coalitions of other males. This is clearly an ancient and adaptive behavior that tends to keep groups together and equitably cared for. In his survey of ancestral-type societies, Boehm found that—in addition to murder and theft—one of the most commonly punished infractions was “failure to share.” Freeloading on the hard work of others and bullying were also high up on the list. Punishments included public ridicule, shunning, and, finally, “assassination of the culprit by the entire group.”
A cave painting from the early Holocene in Spain shows ten figures with bows in their hands and a lone figure prone on the ground with what appear to be ten arrows sticking out of him. The configuration strongly suggests an execution rather than death in combat. Boehm points out that among current-day foraging groups, group execution is one of the most common ways of punishing males who try to claim a disproportionate amount of the group’s resources.
