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.”

Young Spanish Woman Receives Euthanasia After Legal Battle, Sparking Debate

A 25-year-old Spanish woman, Noelia Castillo, received euthanasia on Thursday following a prolonged legal dispute with her father.

She passed away at a care center in Sant Pere de Ribes, about 40 kilometers from Barcelona, where she had been living for some time, according to Spanish media reports.

In an interview broadcast a day earlier on Antena 3, Castillo expressed her exhaustion after enduring prolonged suffering. She indicated that her decision was influenced by a combination of personal circumstances and health-related challenges, including family conflicts and a condition of paraplegia following a previous incident that left her with lasting physical consequences.

Spain legalized euthanasia in 2021, becoming one of the few countries that allow patients under strict conditions to seek medical assistance to end their lives in order to avoid what the law defines as unbearable suffering.

The case has reignited debate in Spain over the ethical, legal, and family dimensions surrounding euthanasia, as well as the broader issue of support for individuals in vulnerable situations.

Over 300 U.S. Troops Wounded Since Start of Iran Conflict, CENTCOM Says

More than 300 U.S. service members have been injured since the start of the conflict with Iran on February 28, the United States Central Command confirmed on Friday.

“Since the beginning of Operation Epic Fury, approximately 303 U.S. service members have been wounded. The vast majority of these injuries are minor, and 273 troops have already returned to duty,” said U.S. Navy Captain Tim Hawkins.

A U.S. official, speaking on condition of anonymity to AFP, indicated that 10 American troops remain seriously injured.

According to the latest figures, an additional 13 U.S. service members have been killed since the conflict began, including seven in the Gulf region and six in Iraq.

Meanwhile, Iran’s armed forces warned on Friday that hotels hosting U.S. troops in the region could be considered legitimate military targets.

“When U.S. forces enter a hotel, from our perspective that hotel becomes American,” said armed forces spokesperson Abolfazl Shekarchi in remarks broadcast on state television.

Iran rejects negotiations as tensions escalate with United States

Iran has no intention of entering negotiations and will continue to resist, Foreign Minister Abbas Araghchi said Wednesday night, dismissing recent statements by U.S. President Donald Trump about possible talks.

Speaking to state television, Araghchi argued that Washington’s call for negotiations reflects a position of weakness. He added that the Islamic Republic seeks to end the war on its own terms, ensuring that such a conflict does not recur in the future.

Meanwhile, the White House issued a stark warning, stating that Trump would “unleash hell” on Iran if it refuses to accept a deal to end the conflict. Despite Tehran’s rejection, U.S. officials maintained that discussions remain ongoing.

White House spokesperson Karoline Leavitt reinforced the administration’s position, warning that failure to acknowledge what she described as Iran’s military defeat would result in even stronger action from Washington.

The increasingly aggressive rhetoric from both sides has diminished hopes for a near-term de-escalation in the conflict, which began following U.S. and Israeli strikes against Iran on February 28.

As tensions continue to rise, the prospect of a diplomatic resolution remains uncertain amid conflicting narratives and escalating threats from both governments.
