‘If Not Pal, Why Good friend-Shaped?’ A Beary Scientific Investigation
Why are bears equally adorable and lethal? Scientific American investigates why these apex predators are “friend-shaped”
There is a meme about bears floating close to the World wide web: “If not buddy, why pal-formed?”
This is an intriguing issue if you make your mind up to take it severely. Most fatal apex predators have a specific ferocity to them that doesn’t scream “friend”—think lions, wolves and crocodiles. So why do bears seem so sweet and cuddly? Have we just been conditioned by teddy bears and Paddington to find them harmless and comforting, or is there a thing else likely on? It turns out that evolution and human psychology might assist us comprehend their mate-shaped mother nature.
“I believe that humans have this massive bias in conditions of how we see bears,” says Rae Wynn-Grant, an ecologist and an affiliated researcher at the University of California, Santa Barbara, who has been finding out bears for 14 a long time. Bears have showcased prominently in folklore in quite a few cultures around the environment, including some Indigenous cultures in North America that have seen the animals as humans’ kin. We have even found bears in the sky and named constellations after them. “We have often identified ourselves to be fairly connected with distinct species of bears,” Wynn-Grant suggests. “We see ourselves in them.”

This deep link may occur, in section, since people and the eight identified species of bears reside in related environments. Folks and bears can have a wide range of habitats, but both equally normally thrive in forested regions near bodies of h2o, this sort of as rivers and lakes. They also have equivalent dietary behaviors as omnivores. Fruits, nuts, honey and meat could make a awesome supper for a black bear or a human.
And then there’s the actual physical resemblance—if you squint. “If a human had been on all fours, they may possibly resemble a bear. And if a bear was upright, it may well resemble a individual,” Wynn-Grant states. She’s not exaggerating: last summer a video clip of a sunshine bear in a Chinese zoo went viral since of how uncannily humanlike it looked while standing on its hind legs. (Wynn-Grant fielded lots of calls from reporters inquiring her to verify that it was, in truth, a bear.)
Continue to, bears have progressed to have lots of characteristics that we really don’t, and at the very least a several of them contribute to their all round close friend-shapedness. For just one, they have fluffy fur, theoretically fantastic for petting. They also have little, rounded ears, which they advanced as an adaptation to preserve heat. Bigger, pointy ears would have a lot more floor space, which would outcome in the more rapidly transfer of heat.

And then there is bears’ big, boopable nose. “When it comes to their sense of scent, that is their superpower,” Wynn-Grant points out. “Polar bears can scent their prey less than the sea ice from exceptionally lengthy distances. So it’s their feeling of odor that genuinely guides them and is a large component of their ecology.”
Why do we come across these characteristics welcoming? It could be that we just think bears glance like dogs, which individuals domesticated over thousands of yrs explicitly to be our pals. Tens of tens of millions of many years back, bears and canine experienced a common ancestor, and they nonetheless share some actual physical traits. In just the purchase Carnivora, the two are each portion of the suborder Caniformia, which refers to “doglike” carnivores. Other caniforms incorporate racoons, seals, crimson pandas and otters—which are very pal-shaped animals.
Some of bears’ features—especially their chubby, rounded face—might also remind us of our very own infants. In the 1940s ethologist Konrad Lorenz proposed a so-referred to as toddler schema to make clear why infants of numerous species have identical characteristics that are distinctive from all those of grownups: huge eyes, a round facial area and plump cheeks. These kinds of physical features could possibly cause a nurturing reaction in humans, a response that allows our offspring endure. Investigate displays that this kind of attributes evoke constructive feelings and social connections that can be measured by looking at modifications in mind activity and amounts of oxytocin, an significant bonding hormone.
Bears are inclined to be quite round, plump creatures. So they could look to be mate-shaped mainly because we have involved those people functions with harmlessness and social bonding. But the simple fact that they appear like our infants does not imply all those associations are accurate.
“Understand that I am like a bear lover, as a result of and by way of. [But] I individually really do not feel that bears glimpse that cuddly. I do not assume that they glance like close friends. When I see bears, I see predators,” Wynn-Grant states. For her operate, “I sedate them and tackle their bodies and do checkups, and I look at their claws and their fangs and stuff. So I’m type of like, ‘Oh, these are vicious animals.’”
The moral of the tale: bears may be mate-shaped, but remaining a great friend to bears doesn’t indicate taming them or reducing their wildness. “I believe that all wild animals must keep on being wild and not domesticated, not held in captivity, unless of course it is for rigorous conservation good reasons,” Wynn-Grant states. “Feeling like, ‘Oh, bears are just hanging out with us they’re ours,’ that actually can move science backward in a direction we do not want.”
