‘If Not Friend, Why Friend-Shaped?’ A Beary Scientific Investigation
Why are bears each cute and lethal? Scientific American investigates why these apex predators are “friend-shaped”

There’s a meme about bears floating across the Web: “If not friend, why friend-shaped?”
That is an intriguing query if you happen to resolve to take it critically. Most dangerous apex predators have a sure ferocity to them that doesn’t scream “friend”—assume lions, wolves and crocodiles. So why do bears appear so cute and cuddly? Have we simply been conditioned by teddy bears and Paddington to seek out them secure and comforting, or is there one thing else occurring? It seems that evolution and human psychology would possibly assist us perceive their friend-shaped nature.
“I think that humans have this huge bias in terms of how we see bears,” says Rae Wynn-Grant, an ecologist and an affiliated researcher on the College of California, Santa Barbara, who has been finding out bears for 14 years. Bears have featured prominently in folklore in lots of cultures world wide, together with some Indigenous cultures in North America which have considered the animals as people’ kin. We now have even seen bears within the sky and named constellations after them. “We have always found ourselves to be quite connected with different species of bears,” Wynn-Grant says. “We see ourselves in them.”

This deep connection would possibly occur, partially, as a result of people and the eight identified species of bears dwell in comparable environments. Individuals and bears can have a wide range of habitats, however each usually thrive in forested areas close to our bodies of water, similar to rivers and lakes. In addition they have comparable dietary habits as omnivores. Fruits, nuts, honey and meat might make a pleasant dinner for a black bear or a human.
After which there’s the bodily resemblance—if you happen to squint. “If a human were on all fours, they might resemble a bear. And if a bear was upright, it might resemble a person,” Wynn-Grant says. She’s not exaggerating: final summer season a video of a solar bear in a Chinese language zoo went viral due to how uncannily humanlike it appeared whereas standing on its hind legs. (Wynn-Grant fielded many calls from reporters asking her to substantiate that it was, certainly, a bear.)
Nonetheless, bears have developed to have loads of options that we do not, and at the very least just a few of them contribute to their general friend-shapedness. For one, they’ve fluffy fur, theoretically excellent for petting. In addition they have small, rounded ears, which they developed as an adaptation to preserve warmth. Larger, pointy ears would have extra floor space, which might outcome within the quicker switch of warmth.

After which there’s bears’ massive, boopable nostril. “When it comes to their sense of smell, that is their superpower,” Wynn-Grant explains. “Polar bears can smell their prey under the sea ice from incredibly long distances. So it’s their sense of smell that really guides them and is a huge part of their ecology.”
Why do we discover these options pleasant? It might be that we merely assume bears appear like canine, which people domesticated over 1000’s of years explicitly to be our buddies. Tens of tens of millions of years in the past, bears and canine had a typical ancestor, and so they nonetheless share some bodily traits. Throughout the order Carnivora, the 2 are each a part of the suborder Caniformia, which refers to “doglike” carnivores. Different caniforms embrace racoons, seals, purple pandas and otters—that are fairly friend-shaped animals.
A few of bears’ options—particularly their chubby, rounded face—may additionally remind us of our personal infants. Within the Forties ethologist Konrad Lorenz proposed a so-called child schema to clarify why infants of many species have comparable options which can be distinct from these of adults: massive eyes, a spherical face and plump cheeks. These types of bodily traits would possibly set off a nurturing response in people, a response that helps our offspring survive. Analysis exhibits that such traits evoke constructive feelings and social connections that may be measured by adjustments in mind exercise and ranges of oxytocin, an necessary bonding hormone.
Bears are typically very spherical, plump creatures. So they could look like friend-shaped as a result of we’ve got related these options with harmlessness and social bonding. However the truth that they appear like our infants doesn’t imply these associations are right.
“Understand that I am like a bear lover, through and through. [But] I personally don’t think that bears look that cuddly. I don’t think that they look like friends. When I see bears, I see predators,” Wynn-Grant says. For her work, “I sedate them and handle their bodies and do checkups, and I look at their claws and their fangs and stuff. So I’m kind of like, ‘Oh, these are vicious animals.’”
The ethical of the story: bears could also be friend-shaped, however being a great pal to bears doesn’t imply taming them or minimizing their wildness. “I think that all wild animals should remain wild and not domesticated, not held in captivity, unless it’s for strict conservation reasons,” Wynn-Grant says. “Feeling like, ‘Oh, bears are just hanging out with us; they’re ours,’ that actually can move science backward in a direction we don’t want.”
