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.”

Tensions Escalate in Middle East as U.S. Bombs Iran After Maritime Attacks
The United States launched new strikes against Iran on Wednesday, following President Donald Trump’s warning that Washington would “hit hard” against the Islamic Republic. While Trump ordered the retaliation after attacks on vessels in the Strait of Hormuz, he also said he hoped the latest wave of bombings would end soon and left the door open for renewed negotiations.
U.S. forces “have begun carrying out additional strikes against Iran to further reduce its ability to threaten freedom of navigation in the Strait of Hormuz,” the United States Central Command said in a post on X.
Washington blamed Iran for what it described as “recent unjustified aggression against commercial shipping.”
Iran’s state news agency IRNA reported that explosions were heard in the port cities of Bandar Abbas, Konarak, and Chabahar.
“This is in retaliation for yesterday’s bombing of ships by Iran. If it happens again, it will be much worse,” Trump wrote on social media alongside an image showing what appeared to be a bombing at an Iranian location.
Before ordering the strikes, the U.S. president said that the ceasefire with Iran had ended. Mediators Pakistan and Qatar called for de-escalation, while the United Nations also urged both sides to reduce tensions.
The Strait of Hormuz remains a critical flashpoint in the Middle East conflict, which began in late February after U.S. and Israeli strikes that killed Iran’s Supreme Leader Ali Khamenei.
Iran-linked attacks on at least three vessels in recent days triggered a U.S. offensive against Iranian targets on Tuesday. Tehran responded by launching attacks against Gulf countries that are allies of Washington.

Deadly Drug Trade Rivalry Suspected After Eight Bodies Discovered in Southern Mexico
Eight bodies were found Wednesday along a highway in the southern Mexican state of Chiapas, near the border with Guatemala, in an incident authorities believe may be linked to a dispute over local drug sales.
The victims — six men and two women — were found abandoned on a road in a mountainous area of the municipality of El Bosque, according to the state prosecutor’s office in a statement published on Facebook.
Initial investigations indicate that the killings may be connected to “a dispute over retail drug sales between local criminal groups operating in the region,” the prosecutor’s office said.
Local media reports that several criminal incidents have increased in the area since the beginning of the year.
The road where the bodies were discovered is located in a mountainous region largely inhabited by Indigenous communities. Authorities have not released further details about the victims or possible suspects as the investigation continues.

Regional Naval Operations Strike Drug Cartels, Disrupting Cocaine and Weapons Trafficking Routes
Transnational operations carried out by regional naval forces, including El Salvador’s National Navy, the United States Coast Guard, and Mexico’s Secretariat of the Navy (SEMAR), have dealt significant blows to international drug trafficking organizations.
The operations have not only led to the seizure of massive cocaine shipments, such as the 6.68 metric tons of cocaine valued at approximately $167 million presented last Wednesday by El Salvador’s Security Cabinet, but have also resulted in the confiscation of high-powered weapons allegedly intended as payment to criminal organizations, according to Security Minister Gustavo Villatoro.
“Based on the strength of the data, not just the narratives, we can state that our National Navy has documented the only known operation in the Pacific Ocean in which a criminal organization from the south was transporting drugs and exchanging them with a group from the north for firearms,” Villatoro said.
The exchange of weapons for drugs between criminal groups in the Pacific Ocean represents a logistical method in which South American cartels from countries such as Colombia and Ecuador negotiate with Mexican and Central American organizations to trade military-grade weapons for cocaine shipments.
Regional naval authorities have identified that meeting points located farther from the coastline in international waters make it easier for armed groups to receive supplies and carry out exchanges undetected. As a result, El Salvador’s National Navy deploys teams from the Trident Naval Task Force (FTNT) aboard maritime patrol vessels to intercept these operations.
Initially, the patrol units are ordered to travel up to 200 nautical miles offshore, but later receive instructions from the Maritime Operations Center to extend their missions beyond 1,000 nautical miles, reaching coordinates used by drug trafficking vessels operating in the open sea.
“We cannot lose focus on the routes these criminal organizations use to move drugs,” Minister Villatoro said, emphasizing the importance of maintaining surveillance over the various maritime corridors used for narcotics trafficking.
