experiments also failed as they relied on centralized control, suppression, and fear to gain “cooperation” in executing their initially idealistic plans.
The heart was missing in all these endeavors, reinforced by the notion that nature itself was an unfeeling, unintelligent, mechanical process. Darwin’s writings, however, explicitly contrasted with this premise. “There is no fundamental difference between man and the higher mammals in their mental faculties,” he wrote in his 1871 book The Descent of Man. As far as emotions were concerned, he also asserted that “the lower animals, like man, manifestly feel pleasure and pain, happiness and misery.”
It took over 140 years for scientists to officially confirm this aspect of Darwin’s theory. On July 7, 2012, “The Cambridge Declaration on Consciousness” stated “unequivocally” that “non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of consciousness states along with the capacity to exhibit intentional behaviors. Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological substrates that generate consciousness.” The document acknowledged that “neural networks aroused during affective states in humans are also critically important for generating emotional behaviors in animals.” This includes “all mammals and birds, and many other creatures, including octopuses.”
Research in the late-twentieth century also confirmed Kropotkin’s thesis that sociability is an important factor in survival and in the ongoing evolution of multiple species. There’s even a biochemical basis for this inclination. The hormone oxytocin, which is present in all mammals, buffers the fight-or-flight response in favor of “tend-and-befriend” behavior. This powerful neuropeptide, once thought to be released only in females during labor and milk production, also appears in men when they engage in nurturing activities, including petting and caring for animals. In both sexes, oxytocin heightens learning capacity, social recognition circuits, and pain thresholds. It also helps heal wounds faster, lowers aggression, and creates a sense of connection and well-being.
The wonders of oxytocin have spurred further research into the long-term transformational effects of the human-animal bond itself, leading to an unmistakable conclusion: Caring for others is a part of nature that has taken on a life of its own, moving far beyond parenting direct offspring. Evolution has a heart. It’s much more than a fleshy pump. We ignore its vast connecting wisdom at our peril. And we evolve in direct relation to how consciously we embrace it.
Seeing Is Believing
Social media abounds with animal videos illustrating strong interspecies relationships and heroic acts of protection. Most striking, of course, are interactions between carnivores and creatures that would normally be considered food. In one popular scene, a polar bear gently plays with a Siberian husky. In another clip, a wild deer emerges from the woods to frolic with a large family dog.
“Well, that’s easy to explain,” one scientifically minded colleague told me. “Over thousands of years, our ancestors selected for friendly canines that could be trusted with our chickens, our sheep, our goats, and our children.”
“But how do you account for the overtures made by the polar bear and the deer?” I asked in response. We both shook our heads in silent wonder.
In still another video, we see the stunning effects of oxytocin. An Irish barn cat, who has just given birth, becomes enamored with a group of ducklings nearby. With her system swimming in the ultimate bonding hormone, the feline’s mothering instincts override her hunting instincts. One by one, she carries the hatchlings back to her blanket, not to eat them, but to nurse them. And the fluffy yellow puffballs begin to snuggle, softly chirping, sipping milk alongside her purring newborns! As time goes on, the connection grows stronger, with the fast-growing ducks waddling behind their adoptive mother, towering over their feisty kitten siblings on morning walks to explore the farm.
Granted, these clips mostly feature domesticated animals that were bred to live with other species. But naturalists have also observed coyotes and badgers hunting ground squirrels together, and zebras engaging in cooperative migratory activities with wildebeests. Beyond these scientifically validated examples, thousands of impressive amateur videos have captured supportive, even altruistic behavior among wild animals. Even though they may be willing to kill to protect their family members, however, large herbivores stop fighting when an aggressor backs off. This tendency to avoid fighting to the death, to “live and let live,” is a major characteristic of what I’ve come to call “nonpredatory power.”
Juggling Clichés
Twenty years ago, I heard the first of many talented cowboys waxing poetic on what became a very popular theme. “Humans are predators, and horses are prey animals,” he said during a well-attended lecture-demonstration. “And yet they allow us on their backs. Imagine that, letting a lion on your back! Isn’t that incredible?”
Audiences rarely question this now-oft-repeated notion. However, this colorful yet simplistic interpretation of the horse-human relationship encourages experienced and amateur riders alike to ignore the daily reality of what both species are capable of. In the first place, humans are not carnivores. While some people habitually act predatory in just about any context, Homo sapiens are omnivores with a strange, sometimes-confusing mix of physical and behavioral characteristics. For instance, horses and other herbivores have eyes on the sides of their heads, emphasizing peripheral vision. Humans, like lions, look directly ahead, reinforcing a goal-oriented perspective scientists believe was designed for stalking. Even so, we have no fangs, and our nails can’t rip through paper, let alone flesh. With the teeth and digestive system of a vegetarian, we have to cook our steaks and cut them into bite-size portions — if we choose to go that route. But we can also thrive on plant-based diets.
The problem is we’ve grown up in a culture of conquerors where predatory behavior is rewarded in far too many businesses and reinforced in far too many schools (especially in the highly competitive, sometimes-cutthroat world of higher education). Those who refuse to claw their way to the top often have trouble imagining an alternative because popular metaphors related to power are almost exclusively carnivorous.
The persistent image of humans as predators actually disempowers more sensitive members of the population. Remember, misrepresentations of Darwin’s theories were promoted throughout the twentieth century to justify aggressive, opportunistic corporate and political interests. During that time, it was also useful to portray nonpredatory animals as gutless, anxiety-ridden prey. Gentle, caring people often follow suit, neglecting the skills needed to use power effectively, sometimes even accepting the role of victim because they can’t stomach becoming a tyrant.
In nature, however, carnivores and herbivores both display intelligent, richly nuanced behaviors that contradict stereotypes. Horses, zebras, water buffalo, and elk will often graze relatively unconcerned as a predator who has recently eaten a big meal walks through their pasture. Yet when an agile carnivore is on the prowl, large herds will scatter long before the predator can get close. Nonpredatory animals conserve energy for true emergencies by assessing the intentions and emotional states of other species at a distance.
This is why horses allow humans on their backs. As we go through the various rituals necessary to ride them, they can tell we’re not planning to eat them. But here’s where it gets tricky for humans who deal in clichés. These agile, socially intelligent animals also understand the difference between mutually respectful, supportive behavior and aggressive, needlessly controlling behavior.
Dominant and/or more sensitive herd members have even higher standards for anyone who adopts the physically intimate leadership role that riding requires. It’s also important to remember that horses like to play games with power, speed, boundaries, and assertiveness. Young stallions in particular are not at all shy about challenging a two-legged handler in the same ways they’re accustomed to sparring with one another. Older, more experienced horses tend to be calmer and more accommodating around people, but they also know how to drive off predators.
In this context, it’s especially important to remember that herbivores sometimes choose fight over flight, and not only when cornered. If you’re naïve, presumptuous, or ornery enough to act like a predator in their presence,
