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.”

WHO worker killed as Israeli forces fire on Gaza medical convoy

An employee of the World Health Organization (WHO) was killed on Monday in Gaza Strip after Israeli forces opened fire on a medical convoy transporting patients for evacuation, according to witnesses and official accounts.

The Israel Defense Forces (IDF) said the vehicle approached troops in a “threatening manner,” alleging that the driver accelerated toward soldiers despite warning shots. “The troops fired warning shots. The vehicle continued advancing, and additional fire was directed at it,” the military said in a statement.

The army also claimed the vehicle lacked clear markings and was therefore treated as a potential threat.

However, survivors disputed that account. Raed Aslan, a passenger in the convoy, told reporters in Khan Younis that the vehicles were clearly marked with WHO insignia. “The vehicle was clearly identified as belonging to the WHO,” he said, adding that an Israeli tank blocked the road and fired at the driver despite the route being empty.

The convoy was transporting patients to the Rafah crossing, the only exit point available for medical evacuations abroad, as Israel does not permit transfers to Jerusalem or the West Bank.

The incident adds to a series of controversial cases involving Israeli military actions against humanitarian convoys. In April 2024, seven workers from World Central Kitchen were killed in an Israeli strike in Deir al-Balah. The military initially cited a “misidentification,” despite the vehicles being clearly marked.

Similarly, in March 2025, 15 paramedics, rescuers, and a UN worker were killed near Rafah. Israeli authorities first claimed emergency lights were off, but video evidence later contradicted that assertion.

A subsequent investigation by organizations including Forensic Architecture found that Israeli forces fired hundreds of rounds at the convoy, and that the vehicles were later destroyed and buried along with the bodies before being recovered days later.

The latest incident is likely to intensify scrutiny over the conduct of military operations in Gaza, particularly regarding the safety of humanitarian personnel and medical evacuations.

NASA’s Orion sets record as farthest crewed mission from Earth

NASA’s Orion spacecraft set a new milestone on Monday, becoming the crewed space mission to travel the farthest distance from Earth, surpassing the record set by Apollo 13, which reached 400,171 kilometers from the planet.

The Orion capsule, part of the Artemis II mission, achieved the record at 12:57 p.m. Eastern Time as it continued its journey toward the gravitational sphere of influence of the Moon.

The milestone came less than an hour before the crew was scheduled to begin observation activities during its planned lunar flyby.

“From here, in the ‘Integrity Cabin,’ as we surpass the greatest distance humans have ever traveled from Earth, we do so honoring the extraordinary efforts and achievements of those who came before us in human space exploration,” said Canadian astronaut Jeremy Hansen.

The mission, which launched last Wednesday from Cape Canaveral, is designed to orbit the Moon and return to Earth within ten days. According to the schedule, the spacecraft is expected to begin its lunar flyby at 2:45 p.m. ET, concluding around 9:20 p.m.

Petro accuses top guerrilla leader of bribing officers to evade military strikes

Colombian President defends his government's social reforms

The president of Colombia, Gustavo Petro, said Saturday that the country’s most wanted guerrilla leader is bribing members of the security forces to obtain advance information and evade military operations.

According to the government, Iván Mordisco, a dissident leader of the now-defunct FARC, is currently on the run in the जंगल following an الجيش bombardment last week that killed six of his closest collaborators in the department of Vaupés.

Authorities believe the guerrilla commander had been at the site shortly before the operation. “He buys off the commanders who are supposed to capture him; that’s how he escapes the bombings, but leaves his own people to die. He is warned before every strike,” Petro wrote on social media platform X.

The six individuals killed in the strike were part of Mordisco’s security ring, according to Defense Minister Pedro Sánchez.

Local media reported that one of those killed was a woman known as “alias Lorena,” who was allegedly Mordisco’s partner and the mother of his child.

After failed attempts to negotiate peace, Petro’s administration has shifted to a more aggressive military strategy against the guerrilla leader. In recent months, three of Mordisco’s brothers have been captured and now face charges including homicide, kidnapping, and arms trafficking.
