The Dividing Line Between Human And Animal Has Been Blurred Again As AI Reveals Startlingly Complex Whale Language

By unlocking the mysteries of how sperm whales communicate and demonstrating their impressive cognitive abilities, researchers hope to get people invested in the fate of these endangered animals.

Sperm whales are chatty.

Their language is markedly different from the deep cetacean moans associated with other whales, taking the form of Morse code-like clicks that boom through the ocean in a decibel range almost twice that of jet engines.

And while we’ve long known animals like monkeys assign specific meaning to short vocalizations varying from alarm calls to affirmations of social rank, sperm whale conversations can endure for an hour or more, with participants exchanging complex strings of clicks that vary depending on context, environment and even which pod family is speaking.

While artificial intelligence has been maligned over the past few years as people grapple with its rapid progress and potential for abuse, it remains the best tool we have for teasing out patterns that our human minds can’t discern, especially from large quantities of data.

With more than 9,000 recordings of sperm whales, Project CETI — Cetacean Translation Initiative, a non-profit effort to decode and translate sperm whale communication — had precisely the kind of huge data cache that AI excels at analyzing.

By feeding the recordings into specially trained machine learning algorithms, the research team was able to identify a wealth of new language patterns. While human languages are composed of quantized morphemes — prefixes, suffixes and root words — whale communication is broken down into sequences of clicks and pauses called “codas.”

Like Morse code, codas make a distinction between short clicks and long clicks. Sperm whales also vary the tempo of the clicks, which could represent inflection, “dialects” or concepts completely alien to the human mind.

“Some of what they’re doing might be totally different from our way of communicating and we’re probably never going to be able to fully grasp those differences,” Oregon State postdoctoral marine researcher Taylor Hersh told NPR.

Researchers believe the “inter-click intervals” — akin to ghost notes in music — may be as significant as the clicks themselves. Importantly, while human ears were able to identify and catalog some of the codas, the machine learning algorithms found many that human analysis missed.

That’s not surprising considering sperm whales — the loudest animals on Earth, capable of generating sounds up to 230 dB — took a much different evolutionary course and, as ocean-dwelling creatures weighing up to 90,000 pounds (40,800 kg) likely have a radically different sensorium compared to humans.

The comparisons to music go further than ghost notes.

“This study shows that coda types are not arbitrary, but rather that they form a newly discovered combinatorial coding system in which the musical concepts of rubato and ornamentation combine with two categorical, context-independent features known as rhythm and tempo, by analogy to musical terminology,” CETI’s team wrote on May 7 while unveiling the most recent study.

While people have used many abilities to mark the dividing line between humans and animals over the years — including the ability to use tools, experience emotions, and demonstrate self-awareness — human capacity for authentic language with syntax and context-dependent meaning was one of the stalwarts, standing the test of time as new research toppled the other dividers by showing animals do indeed use tools, experience rich emotions and have complex inner mental lives.

With this research, scientists are assembling a “sperm whale phonetic alphabet” that will make it easier to discern and catalog whale codas.

To be clear, there’s still a lot of work ahead before scientists can prove sperm whale codas are comparable to human definitions of language, but whether they strictly meet that definition may not matter. After all, it’s clear the clicks and pauses of whale codas are imbued with meaning, even if it remains elusive to us for the moment.

Indeed, “sperm whale communication has both contextual and combinatorial structure not previously observed in whale communication,” the team wrote.

Proving sperm whale codas are tantamount to human language isn’t the goal anyway. The team has two overriding priorities — decode the meanings behind the codas, and get the wider public invested in the fate of these endangered animals by showing they’re not so different from us.

“Our results show there is much more complexity than previously believed,” MIT AI lab director Daniela Rus told NPR, “and this is challenging the current state of the art or state of beliefs about the animal world.”

Owl’s Well That Ends Well For Manhattan’s Most Famous Wild Animal

Flaco the Eurasian Eagle Owl has become a New York celebrity since he escaped his enclosure at the Central Park Zoo early in 2023.

He’s been spotted flying through the concrete canyons of midtown, perched on fire escapes on the upper east side and ridding New York of its vermin — but he’s not your friendly neighborhood Spiderman.

He’s Flaco the Eurasian eagle-owl and New Yorkers have been rooting for him ever since he escaped from a small enclosure in Central Park Zoo and decided the entire park and its environs would be his domain.

Since then, Flaco has evaded capture, put aside concerns that he’d be able to survive in the big city and shocked the hell out of New Yorkers who have seen the curious little guy’s face pressed against the glass of their apartment windows, watching them intently.

“I audibly gasped,” 24-year-old Matt Sweeney told the Wall Street Journal after he realized something or someone was watching him through the window of his upper west side apartment.

“It absolutely scared the you-know-what out of me,” 31-year-old actress Reilly Richardson told the paper after she woke up one morning to find the peeping predator watching her from outside. “It’s New York City. It’s the last thing you expect to see.”

Flaco escaped Central Park Zoo in February after his enclosure, where he lived for 12 years, had been “vandalized,” according to zoo staff. It turns out someone sliced an opening in the mesh, giving Flaco an out which he quickly took advantage of.

For the next few months zookeepers chased him around Central Park, trying to lure him back with food and the recorded sounds of other owls, but Flaco wasn’t having it. In the meantime he became a celebrity, New York’s version of the famous mountain lion P-22, with crowds of birders and curious onlookers assembling to watch and photograph him.

Social media accounts tracking the raptor’s movements sprung up online, and all the attention became too much. Even though zookeepers gave up on returning him to his enclosure, Flaco apparently decided he was done being watched and became the watcher.

Since then he’s popped up all over Manhattan, delighting New Yorkers and giving others a scare as they noticed the two-foot owl tracking them from a fire escape or a window perch. In early November he left the comfy confines of Central Park — possibly spurred by the crowds and commotion of the annual NYC Marathon — and began exploring the city proper, popping up in random places each day.

Initially people were worried Flaco, who had spent his entire life in captivity, wouldn’t be able to feed himself. The owl quickly put those concerns to rest as he proved adept at feasting on New York’s abundant rodents, earning himself the nickname “New York’s Rat Czar” at a time when Mayor Eric Adams has declared war on the vermin.

Experts are divided on why Flaco is spending so much time watching people. As the only known Eurasian eagle owl living “wild” in North America, the little guy may be looking for a mate. They say he won’t find one of his species, but he could find an unpaired female of another species if he’s lucky.

Others say Flaco, who was raised by humans and isn’t afraid of our species, may believe a human could be his mate. That’s another way his predicament mirrors that of P-22, who settled in Los Angeles’ Griffith Park and became a local celebrity, but was cut off from potential mates by busy highways and miles of human-inhabited land.

Flaco
Nan Knighton, whose apartment faces Central Park, snapped this shot of Flaco outside her apartment.

Regardless, people in New York are enchanted by the unusual resident and delighted to see him. Nan Knighton, who took the above photo (via WSJ) told the paper she had an intense encounter with Flaco. After realizing a pair of intense eyes were tracking her inside her home, she made friends with the curious owl:

He stuck around for three hours. 

“I talked to him,” says Knighton, recalling telling Flaco he’s beautiful and gorgeous, and that she couldn’t believe she was speaking to an owl. When she walked into another room, Flaco’s head swiveled to follow her. 

Flaco stayed quiet until Knighton got within 6 inches of his face. “He just let out this little tiny hiss,” she says. “It was kind of like, ‘OK, I like you, but I don’t want to be beak to beak.’”

She turned her back to the owl to write something down. When she looked back, Flaco was gone.

UPDATED: Monkeys Go Missing From Dallas Zoo Weeks After Clouded Leopard Freed From Habitat

Authorities believe the person or people who stole the monkeys intend to sell them as pets or breeding animals.

UPDATE, 2/1/2023: A tip led police to an empty home in Lancaster, Texas, about 15 miles from the zoo. The missing tamarins were found inside a closet and were unharmed, per CNN. They were returned to the zoo and examined by veterinarians.

Police still want to speak to an unidentified man (see story below) who was seen on zoo grounds, but they haven’t said what the man was doing or how he may be connected to the thefts. The abduction of the tamarins follows two other incidents of breached enclosures at the zoo, and the theft of 12 squirrel monkeys from Zoosiana in Broussard, Louisiana, this weekend.

Original story, 1/31/2023:

Dallas police released a photo of a “person of interest” they’d like to speak to after a pair of emperor tamarin monkeys went missing from their enclosure in the Dallas Zoo, the latest of three incidents in which animal habitats at the zoo were breached by human hands.

The first incident happened on Jan. 13 when zookeepers noticed a three-year-old clouded leopard named Nova was missing from her enclosure. They found a breach in the mesh netting that serves as one of enclosure barriers, and said it was a clean, intentional cut with a blade, not from the animals.

After a frantic search — and multiple appeals to the public informing people the leopard was not dangerous and should not be shot — zookeepers found Nova hiding in a tree on the zoo grounds, not far from her enclosure. Nova’s sister, Luna, lives in the same enclosure and remained there.

That same day, staff at the zoo also found another breach, this time at the langur exhibit. Langurs are old-world, leaf-eating monkeys native to Asia. None of the monkeys were missing, but the discovery strengthened the suspicion that someone had tried to steal Nova and at least one monkey, but were not successful.

Now it appears that same person or a copycat has been successful in another habitat. On Jan. 30, zookeepers found a breach in a habitat that hold’s the zoo’s emperor tamarin monkeys. Two of the monkeys were missing.

Tamarins are tiny arboreal new world monkeys that have become popular pets due to “influencers” popularizing them on sites like Youtube and celebrities purchasing them.

There are an estimated 15,000 monkeys living as pets in the US, and some species fetch up to $7,500 as infants, when they’re violently “pulled” from their mothers when they’re just days old and sold. Most are temporary pets, lasting up to two years before docile, adorable infants become destructive, resentful juveniles and the “owners” decide to cut their losses. Buying monkeys as pets and subsequently abandoning them has become so common that sanctuary spots are at a premium, with a handful of sanctuaries taking thousands of monkeys annually.

Some people buy new babies every year or two, shipping the “old” ones off to sanctuaries — or simply dumping them in the woods where they don’t know how to fend for themselves — and repeating the process of infantalizing newly-purchased monkeys. Macaques, capuchins, marmosets and tamarins are the most popular monkeys kept as pets.

Despite the appeal to some people, humans cannot meet the social or environmental needs of monkeys, who naturally live in troops with complex social hierarchies and relationships.

“Monkeys are not surrogate children, and they’re not little people,” the Humane Society’s Debbie Leahy told the New York Post in a 2013 story.

“Pulling” monkeys from their mothers traumatizes infants and the mothers, and there is a wealth of data from primate maternal deprivation studies — going all the way back to the cruel experiments of psychologist Harry Harlow — documenting the psychological damage done to the animals when they’re removed from their mothers and troops.

“If you try to keep them as pets you’re creating a mentally disturbed animal in 99.9 percent of the cases,” Kevin Wright, director of conservation, science and sanctuary at Phoenix Zoo told National Geographic. “The animal will never be able to fit in any other home. Never learn how to get along with other monkeys. And, more often than not, will end up with a lot of behavioral traits that are self-destructive.”

Tamarins, which are often called “pocket monkeys” by people who keep them as pets, can fetch up to $5,000 apiece, generally less than larger primates like capuchins or macaques. Demand for macaques has skyrocketed since the pandemic, as laboratories test various drugs on the old world monkeys, and prices for infants have risen as well.

Despite officials at Dallas Zoo installing additional cameras and increasingly patrols on the grounds at night, an intruder or intruders were able to evade detection and successfully remove the animals some time between Sunday night and Monday morning.

Police have released an image of a man who was seen strolling through the zoo and have asked for the public’s help identifying him so detectives can speak with him. Police did not say why they believe the man, who is pictured wearing a hooded jacket and eating Doritos, would have information on the missing animals or what his role might be.

The People Who Clone Pets Want To Bring Back Extinct Species — And Clone Animals For Their Organs

Genetics, gene-editing and cloning have rapidly matured since the days of Dolly the Sheep, which means we have less time than we think to grapple with some heady moral questions.

Should scientists resurrect long-extinct species? Is it ethical to clone thousands of animals who will not live, but have their organs harvested for human patients?

Those are some of the questions people are asking as the cloning industry — once relegated to producing one-off copies and genetically identical versions of deceased pets for wealthy clients — is expanding with new capabilities.

This story by the BBC’s David Cox provides an informative, brief history of cloning before pivoting to the current state of the industry and how it could continue to evolve.

Two of the most fascinating prospects have to do with conservation. One company, Colossal, is working on bringing back the extinct woolly mammoth, while other scientists are turning to cloning as a way to prevent the extinctions of species like the white rhino, which is functionally extinct without any breeding pairs left living.

Dolly_face_closeup
Scottish scientists shocked the world when they cloned Dolly the Sheep in 1996.

As with anything in science, innovations in cloning unlock new applicative branches, and scientists have partnered with the medical field to address human health concerns. Some, like the practice of editing genes to prevent diseases in newborns, tend to fly under the radar. But others, like the push to adapt organs from animals like pigs so they can be replacements for human organs, are much more controversial and have met opposition from animal welfare groups.

Then there’s the elephant in the room, no pun intended. What about cloning humans?

Right now no one’s gone down that route, at least not publicly, because of the inevitable backlash. What’s happening deep in the bowels of clandestine medical facilities in nations with murky ethics laws is another question entirely.

I am opposed to human cloning, but I don’t believe it will remain the immutable taboo some people think it is. Someone will break the dam, and while that pioneer will likely get raked over the coals, the bell cannot be unrung. Things change so fast these days that what’s shocking one day merits a shrug the next, and it’s possible the world will be introduced to a man or woman one day before it’s revealed the person is, in fact, a clone. (Not unlike the way the world was introduced to Imma, a Japanese influencer and model who exists only digitally.)

Imma
Imma has more than 400,000 Instagram followers, she models the latest fashions and she appears in adverts for products like beverages and watches, but she doesn’t exist. She’s a digital creation.

They’ll be the Dolly the Sheep of the human race, and ethicists won’t get a say in whether they should exist because it’s already been done.

“See how normal they are?” people keen on cloning will say. “They’re just regular people. Are you going to tell them they shouldn’t live?”

But before that, it looks like the movie Gattaca will become reality, and people will order up a great baseball player or a child with intuitive musical genius just like they might commission a piece of art or a custom car job. Gene editing with CRISPR is surprisingly trivial.

Of course, it won’t be lost on people that we’re cloning humans when there are millions of unwanted, uncared-for street kids in the third world, not to mention people who live without the consideration of their fellow human beings in every nation. Just like it hasn’t escaped the notice of activists that South Korea and China are leaders in cloning pets, yet dogs and cats are also food in those countries.

What separates the dogs and cats bound for restaurant kitchens from the dogs and cats having their cells preserved for cloning?

Nothing except for their individual value to humans, just like pure luck separates a cat who finds a loving home from a cat who ends up euthanized with a needle. We are a fickle species.

Yet both the beloved pet and the unwanted shelter cat are sentient, experience intense emotions and have their own thoughts. That’s not conjecture, it’s fact as confirmed many times over experimentally, but it shocks a lot of people. Our education system has not done right by the billions of non-human minds we share our planet with.

Cloned monkeys
These rhesus macaque infants were cloned in a lab in China. The remaining barriers to human cloning are ethical, not technological.

I’ve thought about what might have happened if Buddy had been adopted by someone else, and what his fate may have been. I love the little guy, but it’s possible that someone else may have viewed him as an annoyance, a loud and incessantly chatty cat who needs an inordinate amount of attention and affection, sometimes lashes out, and needs to be surrendered.

Likewise, unwanted cats have languished in shelters for months before viral posts spark interest in them, and suddenly offers to adopt come in by the hundreds from across the globe. Nothing about those cats changed, but humans formed an emotional attachment to them after learning their stories.

Of course, the ethics of how we treat and consider animals can change depending on where you’re sitting. If you’re young, healthy and energetic, your view may be radically different than the person sitting on an organ donation waiting list, knowing their time may be up before a new liver or kidney becomes available. Suddenly a seemingly simple moral calculus becomes murky and complex.

There’s strong evidence that people who take the first steps toward cloning their beloved cats and dogs spend time wrestling with the ethics of the decision as well. Texas-based ViaGen, the western leader in commercial cloning, told the BBC that 90 percent of its clients are not people who have gone through with cloning, but have only taken the initial step of preserving their pets’ cells for $1,600.

And what of the mammoths? Bringing them back from extinction isn’t as simple as filling in the gaps in their genome, implanting gene-edited eggs in female elephants and hoping gestation takes care of the rest. Mammoths are social animals. Will an elephant mother raise a mammoth baby? Where does that mammoth baby belong? Without a herd of its own kind, can it be happy?

We can’t ask the mammoths, and even if we could, it might not be up to them anyway. As one paleogeneticist put it to NPR last year: What if the technology isn’t used to resurrect the mammoth, but to save the elephant? Does the end justify the means in the latter situation, but not the former?
