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.”

Bolivia Orders Three Investigations Into Deadly Military Plane Crash

Bolivia’s Defense Minister Marcelo Salinas announced Monday that three separate investigations will be conducted into Friday’s crash of a military cargo aircraft at El Alto International Airport, near La Paz, which left at least 22 people dead.

The Hercules aircraft, operated by the Fuerza Aérea Boliviana (FAB), was transporting cash intended for the Central Bank of Bolivia when it overshot the runway after landing from the city of Santa Cruz. The plane reportedly traveled nearly one kilometer beyond the airport perimeter.

The incident sparked chaotic scenes, with individuals attempting to collect scattered banknotes. Authorities detained 51 people in the aftermath, and the government declared three days of national mourning.

Multiple Investigations Underway

The first inquiry is being led by a military board from the Bolivian Air Force, which has already taken custody of the aircraft’s black box for analysis.

Minister Salinas said two additional investigations will follow — one conducted by the insurance company and another by the aircraft’s manufacturer.

“At least two more investigations will come, that of the insurance company and that of the aircraft manufacturer,” Salinas said during a press conference in Santa Cruz.

He cautioned that the investigative process could take between three and six months, noting that the black box cannot be opened in Bolivia due to the lack of specialized laboratories for analysis.

Awaiting Official Findings

Salinas stressed that the FAB investigative board is the highest authority in the case and urged the public to wait for its conclusions to avoid speculation about the causes of the crash.

He also confirmed that the government has contacted the families of the 22 victims and the 37 injured, as well as the owners of 15 damaged vehicles, to coordinate procedures with the insurer and cover the corresponding expenses.

Mexico Calls for Immediate Probe After National Dies in ICE Custody

Mexico’s Secretaría de Relaciones Exteriores (SRE) on Monday called on U.S. authorities to conduct an “immediate and thorough” investigation into the death of a Mexican national while in custody of U.S. Immigration and Customs Enforcement (ICE) at a processing facility in California.

In a statement, the Mexican government described the death as “regrettable” and urged U.S. officials to clarify the circumstances surrounding the case in order to “determine responsibilities and ensure that such events do not happen again.”

Death at Adelanto Processing Center

According to available information, the Mexican citizen died at the Adelanto Processing Center in California while under ICE custody. Authorities have not yet released the individual’s identity or the cause of death.

Following the incident, Mexico’s Foreign Ministry formally requested “detailed information” from U.S. authorities, including the detainee’s medical records and custody reports.

Consular Assistance Activated

The Mexican Consulate in San Bernardino, California, has activated consular assistance protocols to provide ongoing support to the deceased’s family. Officials have contacted relatives to express condolences and offer legal guidance, as well as assistance with the necessary procedures to repatriate the remains.

“The handling of situations like this and the establishment of mechanisms to resolve them are priorities for the Government of Mexico,” the Foreign Ministry said, adding that it will formally request an investigation into any systemic conditions that may have contributed to such incidents.

Local Mexican media reported that seven Mexican nationals died while in ICE detention last year — the highest number recorded since the agency was created.

Anti-ICE Billboard Campaign Targets Immigration Spending in 31 U.S. Cities

More than 200 billboards criticizing U.S. Immigration and Customs Enforcement (ICE) began appearing Monday in 31 cities across the United States, including Miami, as part of a campaign highlighting the high cost of immigration enforcement operations for taxpayers.

The initiative, titled “ICE Costs Us,” was launched by the civil rights organization Mijente and will run for four weeks.

Criticism of Spending and Enforcement Tactics

The billboards feature images of ICE agents during arrests or carrying military-style weapons. According to the organization, spending on military-grade equipment for the agency has increased by 600 percent in recent years.

Several signs display messages such as:
“Your taxes are being wasted” and “ICE’s cruelty costs you $28 billion,” referring to the agency’s annual budget.

In a statement, Marisa Franco, co-founder of the Mijente Support Committee, said:
“For too long, our government has prioritized building cages and investing billions in an immigration enforcement apparatus that has left families torn apart and communities terrified.”

She added that “Millions of Americans are living paycheck to paycheck, yet this violent agency continues operating with a blank check. These decisions do not make us safer nor improve our economic security. Our billboards highlight these choices and demand a different path.”

Budget Debate and Medicaid Comparison

The campaign also draws a comparison between ICE’s funding and the estimated 17 million people who could lose health coverage under Medicaid due to federal budget cuts under President Donald Trump.

Other billboard messages seen in various cities include:
“They get billions to beat us; we get layoffs and rising rents” and “Funding ICE is a fast track to fascism.”

Organizers say the goal is to spark public debate about the allocation of federal funds for immigration enforcement and the broader economic and social impact of such policies on communities nationwide.
