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.”

At Least Eight Dead and 19 Injured in Deadly Bus Crash in Veracruz, Mexico
A tragic bus accident in the eastern state of Veracruz left at least eight people dead and 19 others injured on Wednesday afternoon, according to local authorities.
The vehicle was traveling through the town of Zontecomatlán when it crashed near a ravine, state Civil Protection officials reported late Wednesday night. “Regrettably, the prosecutor’s office has confirmed eight fatalities,” the agency stated in an official release.
Emergency Response and Medical Care Rescue teams worked into the night to assist the survivors. The 19 injured passengers were stabilized at the scene before being transported to hospitals in the nearby municipalities of Chicontepec and Huayacocotla. While the identities of the victims have not yet been released, Mexican press reports indicate the bus was en route from Mexico City to Chicontepec.
A Recurring Issue on Mexican Highways Road accidents involving long-haul passenger buses and freight transport are a frequent occurrence in Mexico. Experts often cite excessive speed, mechanical failure, or driver fatigue as the primary catalysts for these tragedies.
This latest incident follows another major disaster in late November, where 10 people were killed and 20 injured in a similar bus crash in the western state of Michoacán. The recurring nature of these accidents continues to spark national debate regarding the enforcement of stricter safety regulations for commercial transport units.

Jair Bolsonaro Hospitalized for Inguinal Hernia Surgery While Serving Sentence for Attempted Coup
Former Brazilian President Jair Bolsonaro, currently serving a 27-year prison sentence for an attempted coup, underwent surgery this Thursday for an inguinal hernia. The procedure took place at the DF Star Hospital in Brasilia, according to his wife, Michelle Bolsonaro.
The 70-year-old former leader left prison on Wednesday for the first time since his incarceration in late November to prepare for the operation. “My love has just gone to the surgical center,” Michelle Bolsonaro posted on Instagram, where she has been documenting her accompaniment during his hospitalization.
Surgical Expectations and Health History Medical professionals treating the far-right ex-president (2019-2022) anticipate the operation will last approximately four hours. His recovery period in the hospital is expected to extend between five and seven days.
Dr. Claudio Birolini explained on Wednesday that while the surgery is standardized, it remains complex due to the patient’s history. Bolsonaro continues to suffer from the long-term effects of a 2018 campaign rally stabbing, an injury that required several major abdominal surgeries in the years following the attack.
“There is no such thing as a simple surgery. However, this is a scheduled and standardized procedure, so we expect it to be carried out without major complications,” Dr. Birolini stated.
Potential Additional Procedures Following the hernia repair, the medical team will evaluate whether Bolsonaro can undergo a second procedure: an anesthetic block of the phrenic nerve. This nerve controls the diaphragm, and the intervention would aim to resolve a chronic case of recurrent hiccups that has plagued the former president for years.
Bolsonaro remains under heavy security at the medical facility as he serves his lengthy sentence related to the events surrounding the January 2023 institutional crisis in Brazil.

Trump Orders Construction of New ‘Golden Fleet’ to Revitalize U.S. Naval Superiority
President Donald Trump issued an executive order this Monday for the immediate construction of two new warships that will bear his name. These vessels will be the pioneers of what he described as the “Golden Fleet,” a future generation of “Trump-class” battleships that he claimed would be “100 times more powerful” than those currently in service.
The announcement took place at his private residence in Mar-a-Lago, Florida. The President indicated that following the initial two ships, the administration aims to commission up to 25 additional vessels. He is scheduled to meet with Florida-based contractors next week to expedite production, criticizing existing defense firms for failing to deliver results efficiently.
This naval expansion is a cornerstone of Trump’s goal to revitalized the American shipbuilding industry and address the strategic gap between the U.S. and competitors like China.
The move comes amid heightened geopolitical tension. Just last week, Trump ordered the seizure of all sanctioned tankers involved with Venezuela’s “ghost fleet” to cripple the country’s crude oil industry. Since December 10, the U.S. military—deployed in the Caribbean under the guise of counter-narcotics operations—has already detained two tankers linked to Venezuelan oil transport.
