Researchers say fossil shows humans, dogs lived in C. America in 10,000 BC

The fossil of a jaw bone could prove that domesticated dogs lived in Central America as far back as 12,000 years ago, according to a study by Latin American scientists.

The dogs, and their masters, potentially lived alongside giant animals, researchers say.

A 1978 dig in Nacaome, northeast Costa Rica, found bone remains from the Late Pleistocene.

Excavations began in the 1990s and produced the remains of a giant horse, Equus sp, a glyptodon (a large armadillo), a mastodon (an ancestor of the modern elephant) and a piece of jaw from what was originally thought to be a coyote skull.

“We thought it was very strange to have a coyote in the Pleistocene, that is to say 12,000 years ago,” Costa Rican researcher Guillermo Vargas told AFP.

“When we started looking at the bone fragments, we started to see characteristics that could have been from a dog.

“So we kept looking, we scanned it… and it showed that it was a dog living with humans 12,000 years ago in Costa Rica.”

The presence of dogs is a sign that humans were also living in a place.

“We thought it was strange that a sample was classified as a coyote because they only arrived in Costa Rica in the 20th century.”

– First of its kind –

The coyote is a relative of the domestic dog, although with a different jaw and more pointed teeth.

“The dog eats the leftovers from human food. Its teeth are not so determinant in its survival,” said Vargas.

“It hunts large prey with its human companions. This sample reflects that difference.”

Humans are believed to have emigrated to the Americas across the Bering Strait from Siberia to Alaska during the last great ice age.

“The first domesticated dogs entered the continent about 15,000 years ago, a product of Asians migrating across the Bering Strait,” said Raul Valadez, a biologist and zooarcheologist from the National Autonomous University of Mexico.

“There have never been dogs without people,” Valadez told AFP by telephone.

The presence of humans during the Pleistocene has been attested in Mexico, Chile and Patagonia, but never in Central America, until now.

“This could be the oldest dog in the Americas,” said Vargas.

So far, the oldest attested dog remains were found in Alaska and are 10,150 years old.

Oxford University has offered to perform DNA and carbon dating tests on the sample to discover more genetic information about the animal and its age.

The fossil is currently held at Costa Rica’s national museum but the sample cannot be re-identified as a dog without validation by a specialist magazine.

“This dog discovery would be the first evidence of humans in Costa Rica during a period much earlier” than currently thought, said Vargas.

“It would show us that there were societies that could keep dogs, that had food surpluses, that had dogs out of desire and that these weren’t war dogs that could cause damage.”

Former South Korean President Yoon sentenced to five years in prison

Former South Korean president Yoon Suk-yeol was sentenced on Friday to five years in prison for obstruction of justice and other charges, concluding the first in a series of trials stemming from his failed attempt to impose martial law in December 2024.

The sentence is shorter than the 10-year prison term sought by prosecutors against the 65-year-old conservative former leader, whose move against Parliament triggered a major political crisis that ultimately led to his removal from office.

Yoon, a former prosecutor, is still facing seven additional trials. One of them, on charges of insurrection, could potentially result in the death penalty.

On Friday, the Seoul Central District Court ruled on one of the multiple secondary cases linked to the affair, which plunged the country into months of mass protests and political instability.

U.S. deportation flight returns venezuelans to Caracas after Maduro’s ouster

A new flight carrying 231 Venezuelans deported from the United States arrived on Friday at the airport serving Caracas, marking the first such arrival since the military operation that ousted and captured President Nicolás Maduro.

On January 3, U.S. forces bombed the Venezuelan capital during an incursion in which Maduro and his wife, Cilia Flores, were captured. Both are now facing narcotrafficking charges in New York.

This was the first U.S.-flagged aircraft transporting migrants to land in Venezuela since the military action ordered by President Donald Trump, who has stated that he is now in charge of the country.

The aircraft departed from Phoenix, Arizona, and landed at Maiquetía International Airport, which serves the Venezuelan capital, at around 10:30 a.m. local time (14:30 GMT), according to AFP reporters on the ground.

The deportees arrived in Venezuela under a repatriation program that remained in place even during the height of the crisis between the two countries, when Maduro was still in power. U.S. planes carrying undocumented Venezuelan migrants continued to arrive throughout last year, despite the military deployment ordered by Trump.

Sheinbaum highlights anti-drug gains after U.S. says challenges remain

Mexican President Claudia Sheinbaum on Friday highlighted her government’s achievements in the fight against drug trafficking, after the United States said challenges remain in combating organized crime.

On Thursday, Mexican Foreign Minister Juan Ramón de la Fuente held talks with his U.S. counterpart, Secretary of State Marco Rubio. Following the meeting, the U.S. State Department said in a statement that “despite progress, challenges still exist” in addressing organized crime.

“There are very strong results from joint cooperation and from the work Mexico is doing: first, a 50% reduction in fentanyl seizures at the U.S. border,” Sheinbaum said during her regular morning press conference.

The president also said that authorities have seized nearly 320 tons of drugs and that there has been a “40% decrease in intentional homicides in Mexico” since the start of her administration on October 1, 2024.

Sheinbaum added that the United States should implement campaigns to reduce drug consumption within its territory and curb the flow of weapons into Mexico.

“There are many results and there will be more, but there must be mutual respect and shared responsibility, as well as respect for our sovereignties,” she said.

On Monday, Sheinbaum held a phone call with U.S. President Donald Trump to discuss security issues. She said she once again ruled out the presence of U.S. troops in Mexico to fight drug cartels.

Security has been a recurring issue used by Trump to threaten tariffs on Mexico and to pressure negotiations over the USMCA (T-MEC) free trade agreement, which are scheduled for 2026.

The agreement is crucial for Mexico’s economy, as about 80% of the country’s exports are destined for the United States.
