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.”

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.”

Rubio signals possible engagement with Iranian factions amid internal divisions

U.S. Secretary of State Marco Rubio said Monday that Washington is hopeful of engaging with factions within the government of Iran, noting that the United States has received positive private signals.

Speaking to ABC News’ Good Morning America, Rubio suggested that internal divisions exist within the Islamic Republic and expressed confidence that figures with the authority to act could emerge.

“We are hopeful that this will be the case,” Rubio said. “Clearly, there are people there who are communicating with us in ways that those previously in power in Iran did not. This is reflected in some of the steps they appear willing to take.”

Despite this, Rubio maintained a firm stance toward Iran, reiterating that the ongoing conflict seeks to eliminate its capacity to develop nuclear weapons—an objective that President Donald Trump has previously claimed was achieved during a military strike last year.

King Charles III to visit the U.S. on first state trip since taking the throne

King Charles III and Queen Camilla will undertake a state visit to the United States on the recommendation of the British government, Buckingham Palace announced on Tuesday, adding that further details will be released at a later date.

The visit aims to highlight the historic ties and current relationship between the United Kingdom and the United States, as both countries prepare to mark the 250th anniversary of American independence in 2026.

The trip is expected to take place at the end of April and follows U.S. President Donald Trump’s visit to the United Kingdom last year, which sought to strengthen bilateral relations.

This will be Charles III’s first state visit to the United States since ascending to the throne in 2022, although he previously traveled there 19 times as Prince of Wales.

By comparison, Queen Elizabeth II made four state visits to the United States—in 1957, 1976, 1991, and 2007—while U.S. presidents have carried out four state visits to the United Kingdom since 1952, in 2003, 2011, 2019, and 2025.

Following the U.S. trip, the monarch is also expected to travel to Bermuda, marking his first official visit to the territory since becoming head of state.

The visit comes amid tensions between the two countries due to differences between President Trump and British Prime Minister Keir Starmer over the war in Iran. Starmer has reiterated that the United Kingdom will not take part in the conflict, although it will defend its interests and support allies in the Persian Gulf.

Trump has criticized that stance, urging countries not involved in the military campaign to act decisively, stating that “the hardest part is already done.”

The trip also follows a request by U.S. Congressman Ro Khanna, who called on the king to meet privately with victims linked to convicted sex offender Jeffrey Epstein during his stay.

The case has also involved the king’s brother, Prince Andrew, who has faced scrutiny over his past associations with Epstein. The former royal, stripped of his titles and honors, has denied any wrongdoing despite ongoing allegations and investigations.

Leopoldo López thanks Spain for fast-track citizenship but says “I am still Venezuelan”

Venezuelan opposition leader Leopoldo López expressed gratitude on Tuesday to the Government of Spain after being granted Spanish citizenship through an expedited process, following the revocation of his Venezuelan nationality by the administration of Nicolás Maduro.

Speaking in Madrid, López acknowledged the gesture but admitted having mixed emotions. “I am grateful to the Spanish government for granting me citizenship, but I have mixed feelings, as do millions of Venezuelans who have had to leave their country. It is not easy,” he said.

The opposition figure highlighted Spain’s role as a refuge for Venezuelans, while emphasizing that his identity remains unchanged. “Spain has been, for me, my family, and hundreds of thousands of Venezuelans, a homeland away from home. That does not mean we stop being Venezuelan. I am Venezuelan, I carry Venezuela in my heart, and everything I have done has been for Venezuela,” he added.

López requested Spanish nationality after the Venezuelan government stripped him of his citizenship in October, accusing him of promoting a “military invasion,” a move that left him effectively stateless.

Initially, he applied through the standard process in late 2025 but, unable to meet the requirements, later sought nationality through a special mechanism known as “carta de naturaleza,” with the support of Spain’s foreign minister, José Manuel Albares.

To support his application, López submitted documentation from the Inter-American Court of Human Rights, which determined that he had been a victim of political persecution, arbitrary detention, imprisonment, and other actions by the Venezuelan government.

“For me, this has been a long journey. The persecution by the dictatorship against me began many years ago. I was banned, persecuted, censored, imprisoned, and sentenced to 14 years in prison. I had to escape from Venezuela, from prison,” he said.

Spain’s decision to grant him citizenship through an exceptional procedure was justified by his “very special situation,” including the lack of documentation and legal status.
