“Dog is man’s best friend” may be an ancient cliché, but when that friendship began is a longstanding question among scientists. A study led by a University of Arizona researcher is one step closer to an answer to how Indigenous people in the Americas interacted with early dogs and wolves.
The study, published in the journal Science Advances and based on archaeological remains from Alaska, shows that people and the ancestors of today’s dogs began forming close relationships as early as 12,000 years ago—about 2,000 years earlier than previously recorded in the Americas.
“We now have evidence that canids and people had close relationships earlier than we knew they did in the Americas,” said lead study author François Lanoë, an assistant research professor in the U of A School of Anthropology in the College of Social and Behavioral Sciences.

“People like me who are interested in the peopling of the Americas are very interested in knowing if those first Americans came with dogs,” Lanoë added. “Until you find those animals in archaeological sites, we can speculate about it, but it’s hard to prove one way or another. So, this is a significant contribution.”
Lanoë and his colleagues unearthed a tibia, or lower-leg bone, of an adult canine in 2018 at a longstanding archaeological site in Alaska called Swan Point, about 70 miles southeast of Fairbanks. Radiocarbon dating showed that the canine was alive about 12,000 years ago, near the end of the Ice Age.
Another excavation by the researchers in June 2023—of an 8,100-year-old canine jawbone at a nearby site called Hollembaek Hill, south of Delta Junction—also shows signs of possible domestication.
The smoking gun? A belly of fish
Chemical analyses of both bones found substantial contributions from salmon proteins, meaning the canine had regularly eaten the fish. This was not typical of canines in the area during that time, as they hunted land animals almost exclusively. The most likely explanation for salmon showing up in the animal’s diet? Dependence on humans.
“This is the smoking gun because they’re not really going after salmon in the wild,” said study co-author Ben Potter, an archaeologist with the University of Alaska Fairbanks.

The researchers are confident that the Swan Point canine helps establish the earliest known close relationships between humans and canines in the Americas. But it’s too early to say whether the discovery is the earliest domesticated dog in the Americas.
That is why the study is valuable, Potter said, “It asks the existential question, what is a dog?”
The Swan Point and Hollembaek Hill specimens may be too old to be genetically related to other known, more recent dog populations, Lanoë said.
“Behaviorally, they seem to be like dogs, as they ate salmon provided by people,” Lanoë said, “but genetically, they’re not related to anything we know.”
He noted that they could have been tamed wolves rather than fully domesticated dogs.

‘We still had our companions’
The study represents another chapter in a longstanding partnership with tribal communities in Alaska’s Tanana Valley, where archaeologists have worked since the 1930s, said study co-author Josh Reuther, an archaeologist with the University of Alaska Museum of the North.

Researchers regularly present their plans to the Healy Lake Village Council, which represents the Mendas Cha’ag people indigenous to the area, before undertaking studies, including this one. The council also authorized the genetic testing of the study’s new specimens.
Evelynn Combs, a Healy Lake member, grew up in the Tanana Valley, exploring dig sites as a kid and taking in what she learned from archaeologists. She’s known Lanoë, Potter and Reuther since she was a teenager. Now an archaeologist herself, Combs works for the tribe’s cultural preservation office.
“It is little—but it is profound—to get the proper permission and to respect those who live on that land,” Combs said.

Healy Lake members, Combs said, have long considered their dogs to be mystic companions. Today, nearly every resident in her village, she said, is closely bonded to one dog. Combs spent her childhood exploring her village alongside Rosebud, a Labrador retriever mix.
“I really like the idea that, in the record, however long ago, it is a repeatable cultural experience that I have this relationship and this level of love with my dog,” she said.
“I know that throughout history, these relationships have always been present. I really love that we can look at the record and see that, thousands of years ago, we still had our companions.”

Alaska Gov. Mike Dunleavy and the members of the state’s congressional delegation celebrated the lighting ceremony for this year’s U.S. Capitol Christmas Tree — which came from Alaska — on Tuesday in Washington, D.C.
This year’s tree, an 80-foot Sitka spruce, came from the Tongass National Forest. The only other Capitol Christmas Tree to come from Alaska was taken from the Chugach National Forest in 2015.

A fourth grader from Kenai, Rose Burke, also attended the ceremony alongside U.S. House Speaker Mike Johnson.
“Just like Alaska, it is big and beautiful,” said Burke, who won the U.S. Capitol Christmas Tree Essay Contest.
Also present were members of the Wrangell Cooperative Association, who sang and gave a blessing to the tree as part of the ceremony.
Thirteen hours after boarding a jet in Seattle recently, I stepped off onto Asian soil, breezing through customs and into an air-conditioned subway.
I was bound for a city of skyscrapers, art, soup dumplings and glorious urban hiking: Taipei.
Maybe you already know a little bit about Taiwan, the nation of some 23 million people.

Some outdoorsy Alaskans have ridden the Huandao, a network of bike paths and roads that circumnavigate the mountainous island.
Or you’ve read about Taiwan on the news — how it’s under constant threat from China, its saber-rattling neighbor across an 80-mile strait.
Allow me to take you on a quick diversion to Asia from your regular life, to explain why Taiwan, which I visited in late October, matters to Alaska — and the rest of the world.
Martial law to progressive democracy
Two years ago, I took a trip to Japan, and while I was there, I made a side visit to Taiwan.
At the time, I was contemplating the idea of working as a foreign correspondent, perhaps in Hong Kong. But a friend who’d worked in journalism in Asia suggested I check out Taiwan instead, because Hong Kong’s future appeared increasingly depressing: The Chinese government had crushed the region’s pro-democracy protests, leaving little drama or nuance to report on.

The friend was right: Last week, dozens of demonstrators were sentenced to up to a decade in prison.
Taiwan’s future, by contrast, was setting up to be a compelling drama — one that’s still playing out today.
A quick history lesson. For centuries, Taiwan’s Indigenous population has shared the island with people of mainland Chinese heritage, who migrated there in waves. One of the largest waves came in the late 1940s.
That’s when more than 1 million Chinese nationalists, led by Chiang Kai-Shek, fled to the island after losing their country’s civil war to the communists, led by Mao Zedong.
Chiang became the leader of Taiwan, but once there, his government, in hopes of retaking the mainland, continued referring to itself as the Republic of China — a name that Taiwan still uses today.

Chiang’s rule over Taiwan was authoritarian and repressive: His forces killed tens of thousands of people during an
anti-government uprising in 1947, with tens of thousands more killed and imprisoned during four subsequent decades of martial law — a period known as the White Terror.
But in the 1980s and 1990s, something surprising happened: Taiwan evolved into a thriving, progressive democracy.
Earlier this year, the Taiwanese people elected a new president, Lai Ching-te,in free and fair elections. Taiwan was the first Asian country to legalize same-sex marriage, in 2019. It holds an enormous annual Pride celebration in Taipei — this year’s included a speech from the vice president. There are regular protests and the country’s parliament hosts robust debate — including periodic fistfights.
The presence of that kind of open, democratic society — so close to China, and with a military supported by arms from the U.S. — risks serving as an inspiration to people living under Communist Party rule on the mainland. And it’s not the type of inspiration that the Communist Party likes.
Taiwan needs allies
On my previous trip to the island, I made some new friends and picked up on some of these political themes between bike rides, pork buns, monkey viewing and a Taiwan Series baseball game.

When I got home, I stayed up on Taiwan related news and kept talking about the country with an Anchorage friend of Taiwanese heritage.
He, in turn, connected me with the Taiwanese government’s officein Seattle. Which, as it turns out, is always looking for interested journalists to invite to the island.
After a brief correspondence, I was told, in February, to block off a week in October for an official visit.
I arrived back in Taipei on a Friday afternoon — just in time for dinner with a couple of Alaska friends who had also traveled to Taiwan for a bike trip. We sat outside next to a fish market, eating skewers of grilled beef, veggies and scallops, before I rode the mile back to my hotel room on one of Taipei’s ubiquitous shared bicycles — rentable for about a dollar an hour with a smartphone.
The next day I watched the Pride parade, a raucous festival of queer culture with floats sponsored by Uber and Google.
Another bike ride took me to a train to a bus, for an overnight stay in Taiwan’s northeast corner. I spent it in Jiufen, a mountainside getaway of tea rooms and guesthouses, then hiked and explored markets and museums the next day before returning to Taipei for the start of my official visit.
More about the official part: To preserve their relations with China, all but roughly a dozen of the world’s countries decline to give Taiwan formal diplomatic recognition — meaning that its government has to get creative to forge ties with sympathetic populations.

A few times a year, the Ministry of Foreign Affairs, or MOFA, pays for an entire delegation of journalists to spend a week in the country — mostly for meetings with government officials, but also for gorging themselves on Taiwan’s delectable cuisine and viewing tourist attractions like a remarkably lifelike miniature cabbage carved from jade.
For me, this entailed criss-crossing Taipei in a curtain-festooned tour bus with a very solicitous MOFA staff member and a dozen other reporters — from Haiti, Slovakia, the Netherlands, Canada, Italy, Australia, Finland, Nigeria and South Korea.
The initiative is hosting around 100 reporters this year at a total cost of some $500,000, which largely pays for journalists’ flights and hotels, according to MOFA officials. To maintain my independence and credibility in reporting on Taiwan, I combined my trip with a vacation, paid for my own plane ticket to Taipei and found a cheap AirBnB; I did not pay for the group meals hosted by MOFA.
“We try to make friends with the rest of the world,” Catherine Hsu, a top MOFA official, told us over the fanciest lunch I’d ever eaten — seven courses dished out at a hotel restaurant inside Taipei’s main railway station.

Taiwan needs friends because without them, it stands little chance against its large, powerful neighbor across the strait.
Taiwan is an economic powerhouse: Its biggest company, Taiwan Semiconductor Manufacturing Co., is the global leader in high performance semiconductors and has been valued at more than $1 trillion; the island also is home to other semiconductor businesses and high-tech industries.
But even a country whose per-person gross domestic product is in line with Israel’s and Spain’s can’t compete with the blunt force threatened by China, which calls Taiwan a “sacred and inseparable part” of its territory and vows to reunify it.
Taiwan currently spends some $20 billion a year on national defense, and military infrastructure and bomb shelters dot the island. But China’s defense budget is roughly 10 times that, and it regularly conducts menacing military drills — in one recent case, simulating a blockade of Taiwan and in another, launching missiles that flew over the island.
As Lai, the Taiwanese president, visited Hawaii this week just after a newly approved U.S. arms sale, China’s military issued a statement saying it would “resolutely crush any ‘Taiwan independence’ separatists.”
‘We will play an important role’
Over our week in Taiwan, my group was ushered from ministry to ministry, with briefings on subjects like the nation’s network of high-tech industrial parks and its efforts to transition toward more climate-friendly energy sources.

But many of our meetings were dominated by a force that wasn’t in the room: China. We heard from criminal investigators about how Taiwan’s decades-long exclusion from the United Nations, at China’s behest, means it can’t participate in Interpol, the international policing organization. It has also been blocked from formal membership in the World Health Organization and the U.N.’s official climate talks.
Think tank officials reeled off polling data about Taiwanese citizens’ willingness to take up arms against China. And media fact-checkers told us about disinformation campaigns suspected to be seeded by China-aligned operatives.
Anchorage Democratic Sen. Bill Wielechowski also visited the country earlier this year and came away with similar impressions.
“The whole country, their whole identity is wrapped up in this notion that, at any time, China could come in and take over,” Wielechowski told me.
Wielechowski, who traveled with another Alaska state senator, Anchorage Democrat Elvi Gray-Jackson, is the latest in a long line of Alaska politicians to establish ties with Taiwan. Republican former Gov. Frank Murkowski is also a longtime ally, having taken more than two dozen trips to the country and served as an observer at Taiwan’s presidential elections.

Wielechowski’s and Gray-Jackson’s primary interest in Taiwan was foreign trade and reviving once-robust sales of Alaska products to the country. The state formerly had a trade office in Taipei, supporting substantial exports of Alaska timber and oil, and the two are interested in reviving it.
But Taiwan’s future is also directly relevant to Alaskans because of how Chinese military action could prompt an American response.
Alaska military bases host dozens of U.S. fighter jets, and experts say that if there’s any kind of conflict over Taiwan, their pilots and support crews are very likely to be dispatched to the Pacific.
“Look, I’m not going into war plan stuff, because that’s all classified and everything,” GOP U.S. Sen. Dan Sullivan told me last week. But, he added, two hours before our conversation, he’d had a discussion with Admiral Samuel Paparo, the commander of some 380,000 U.S. Indo-Pacific forces and civilians.
“We will play an important role,” Sullivan said. “We have a lot of forces, who are very close to the theater — closer than Hawaii. A major conflict in the Taiwan Strait would significantly impact the active duty forces in Alaska.”
Uncertainty with a new U.S. president
Sullivan, a former U.S. Marine, was once deployed to the Taiwan Strait and has since visited the country several times as a senator.

He’s been a key Republican ally of Taiwan in the U.S. Congress, amid an increasing penchant for isolationism among members of his party.
His staff sent me a 24-page booklet — “A Test of Wills: Why Taiwan Matters” — that it had made out of a series of Sullivan’s policy speeches.
But it’s too early to say if his views will win out in the new presidential administration. A Wall Street Journal correspondent shadowed Sullivan in Asia earlier this year, with the
resulting profile headlined: “A GOP Hawk Tries to Reassure a World on Edge About Trump.”
“In Taipei and Singapore, Sen. Dan Sullivan looks to quell foreign leaders’ fears that the U.S. won’t stand by allies if Trump wins,” the subhed reads. The piece describes Sullivan telling Taiwan’s vice president that “you can count on the United States of America,” but added that that promise “wasn’t wholly within (Sullivan’s) power to keep.”
My visit to Taiwan was just before Donald Trump won his second term. The U.S. election came up at nearly every meeting, with my fellow journalists repeatedly pressing Taiwanese officials on how they’d deal with Trump if he took office again.

Previously, Trump has said that Taiwan should pay the U.S. for its defense and complained that the island’s semiconductor industry is stealing American jobs; a former top aide said Taiwan could be “toast” if Trump was re-elected.
Taiwanese officials largely brushed off those comments and said they could work with Trump; one jokingly told us that, as a businessman, perhaps Trump could broker a deal to sell Taiwan some state-of-the-art F-35 fighter jets.
(The very solicitous Ministry of Foreign Affairs staffer followed up the next day with a group text requesting that the comment be considered off-the-record; I politely refused, given that the relatively high-ranking official declined to walk it back himself when given the opportunity immediately after he spoke.)
In our interview, Sullivan pointed out that Republican U.S. Sen. J.D. Vance, the vice president-elect, has spoken “publicly and very strongly” of the geopolitical importance of Taiwan — even as Vance has been much more skeptical of U.S. support for Ukraine.
But there’s little doubt that the election results are injecting new uncertainty into what’s long been an important alliance between the U.S. and Taiwan — at a time when the island is under increasing pressure not just militarily but economically.
Earlier this month, Reuters reported that SpaceX — run by Trump booster Elon Musk—asked some of its Taiwanese suppliers to transfer manufacturing to other countries because of China’s military threat.The news agency also reported last year that offshore wind power developers are increasingly thinking about how to insure their projects in the Taiwan Strait against events like war.

How, exactly, the U.S. should respond to these developments isn’t a question for me — it’s a question for the American public and its elected officials. And the public just gave those officials some strong signals by electing Trump.
There are compelling reasons for America to avoid another foreign military entanglement, which, in Taiwan, would almost certainly put Alaska service members in harm’s way.
But I’ve also seen Taiwan twice now, with my own eyes, and I can attest to what’s at stake. Its mist-flanked mountains, modern skyscrapers and high-tech semiconductor foundries. Its nightclubs and queer culture. And, most importantly, a democratic society where political and cultural freedoms have flowered in the ashes of an authoritarian past.
“They say, ‘Today, Ukraine,’” one of the Taiwanese officials told us on our visit. “‘Tomorrow might be Taiwan.’”

A new report that highlights how changing climate affects travel safety and the abundance of polar bears on land in Northwest Alaska was released this week.
The first Alaska’s Changing Environment report came out in 2019 and focused on physical and biological changes in Alaska.
This year’s edition, Alaska’s Changing Environment 2.0, updates long-term climate trends and looks at changes that have emerged or intensified in recent years, saidHeather McFarland, science communications lead at Alaska Center for Climate Assessment and Policy at the University of Alaska Fairbanks International Arctic Research Center.

Polar bears are spending more time on shore
Among dozens of scientists and Indigenous experts across the state who contributed to the report, some spoke about the changes affecting the North Slope and Northwest Arctic regions — for example, an increased polar bear presence around some communities.
Kaktovik resident Carla SimsKayotuk said in the report that she sees many more bears around her village.
“There are over 60 polar bears around our area,” SimsKayotuk, also an observer with the Alaska Arctic Observatory and Knowledge Hub, said in September.
As sea ice declines, more polar bears spend more time on land: Since the 1980s, the percentage of polar bears summering on shore increased from 5 to 30% in the Southern Beaufort Sea, and from 10 to 50% in the Chukchi Sea. Both populations spent about 30 days more on land.
“There’s been a continuous increase in the amount of time bears spend on land, and also what proportion comes on land in the summertime,” said Research Wildlife Biologist at the U.S. Geological Survey, Karyn Rode, who has been studying polar bears for several decades. “It is at least partly driven by the amount of sea ice available during the summer.”
Rode explained that when the ice retreats north, polar bears have a choice to stay with that ice and retreat toward the pole, farther away from the most productive ocean habitat, or to drop off and come on land.

“Bears that come on land have the benefit that there are bowhead whale carcasses from subsistence hunts, and the majority of bears that come on land will visit those,” she said.
Rode said that by 2040, the scientists forecast that about 50% of the Southern Beaufort Sea polar bear population would be coming on shore, increasing their time on land by another 40 days.
Now that polar bears are close to infrastructure more often, scientists wonder how they are responding to human-related disturbances. Todd Brinkman, associate professor at UAF’s Institute of Arctic Biology, led a research project looking at the effects of aircraft on bears.
“Bears were responding more strongly to helicopter activity than aircraft,” he said.
Brinkman said that in normal conditions when aircraft can fly high, above 1,500 feet, it doesn’t significantly affect the bears, However, when conditions change, and there is a low ceiling, aircraft has to fly lower, and there’s a greater opportunity for a disturbance.

Brinkman is also leading a study that looks at how increasing ship traffic might affect bears.
Polar bears on land are closer to people, which can create opportunities for tourism, as well as for human-bear conflicts, the report said.
Rode said that so far, she is not aware of data suggesting more conflicts.
Brinkman said that researchers, the U.S. Fish and Wildlife Service and the North Slope Borough Department of Wildlife Management staff are discussing what studies can address direct interactions between humans and bears. He said that one example the research could take is looking at the effectiveness of different deterrents or hazing techniques to pull a bear away from communities, but there are various ways to approach the question.
“The communities need to be part of this,” Brinkman said. “They need to really guide the research so whatever information we generate is useful to them, and it can help them make decisions.”

Unreliable ice makes travel more dangerous
The report highlighted the warming in the Northwest Arctic region and its effects on the residents.
Specifically, Kotzebue resident and observer Bobby Schaeffer said in the report that the changing climate has led to more difficult and dangerous travel, and, as a result, postponed activities and altered hunting season.
According to the report, Kotzebue Sound has warmed 12 degrees since the 1980s, and the freeze-up and break-up times have shifted.
Schaeffer said that when he was growing up in the ‘50s, he remembers having nine months of winter and three months of summer. Throughout his life, the climate has been changing.
“Rather than three months summers, we started having six months summers, early spring and late fall, about a month on each side,” he said.
This year, Kotzebue saw below-zero temperature for the first time on Nov. 26 — something that would happen in early September when Schaeffer was a child. It takes longer for the temperatures to drop and for the water to fully freeze up.

With longer periods of open water, the region started getting more frequent and intense storms.
“People are getting more concerned about massive storms,” Schaeffer said. “We’ve never had those when I was growing up, but now they’re more frequent, and they’re getting stronger.”
The ice around Kotzebue is affected too.
“It’s not getting thick anymore, and we are hunting closer and closer to land because that’s where the leads are now,” he said.
With slow freeze-up in the fall, hunters need to wait until they know the ice is thick enough before they can go out and try to hunt or fish, Schaeffer said. In turn, in spring, the snow disappears quickly, and the sun shines directly onto the ice, making it thin, especially around the channels where the current is the strongest, and near shallow sandbar areas, he said.
“It doesn’t take very long for it to get dangerous,” he said. “People fall in both times, both fall and spring. … People have lost their lives because of trying to traverse across the ice.”
