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.”

Authorities Say Teotihuacán Gunman Was Obsessed With Mass Shootings and Extremist Symbolism
Julio César Jasso Ramírez, identified by authorities as the gunman behind the armed attack at the archaeological site of Teotihuacán, had allegedly spent years building a personal narrative shaped by an obsession with historical mass shootings, extremist symbolism, and an increasing detachment from reality.
According to preliminary findings from the Fiscalía General de Justicia del Estado de México, the 27-year-old suspect, originally from the southern Mexican state of Oaxaca, acted alone and appeared to have carefully planned the attack.
Investigators also pointed to signs of a severe psychological or psychiatric disorder. One official involved in the case stated that the suspect seemed to live in “his own reality,” disconnected from the world around him.
“I would not speak of a motive; I would speak of psychopathy, a condition, an illness,” the official said while discussing the ongoing investigation.
Authorities reported that Jasso Ramírez was allegedly fixated on mass violence incidents that occurred outside Mexico, particularly in the United States.
Among the items found in his possession were writings, images, and materials reportedly linked to the Columbine High School massacre, the school shooting that took place on April 20, 1999.
The investigation remains ongoing as authorities continue analyzing evidence connected to the suspect’s background and mental state.

Iran refuses to reopen strait of Hormuz amid ongoing U.S. Naval blockade
Iran reaffirmed on Wednesday that it will not reopen the Strait of Hormuz while the United States maintains its naval blockade against Iranian ports and vessels, amid rising geopolitical tensions in the region.
Iranian Parliament Speaker Mohamad Baqer Qalibaf warned that reopening the crucial maritime route depends on Washington honoring the ceasefire agreement. According to Qalibaf, Iran considers the deal to be violated due to ongoing U.S. actions.
The Iranian official accused the United States of carrying out a “naval blockade and the hijacking of the global economy,” while also pointing to Israeli military operations in Lebanon as part of the broader conflict affecting the region.
Qalibaf stated that military and economic pressure would not force Iran to change its position. “The United States and Israel failed to achieve their goals through military aggression, and they will not succeed through intimidation. The only path forward is to recognize the rights of the Iranian nation,” he said.
His remarks come amid stalled negotiations between Iran and the United States following direct talks held on April 11 and 12 in Islamabad.
The discussions, led by U.S. Vice President JD Vance and Iranian representatives, have shown little progress in recent days, increasing uncertainty over whether dialogue between the two sides will resume.
U.S. President Donald Trump recently announced an extension of the ceasefire but decided to keep the naval blockade in place, a move Tehran considers incompatible with ongoing negotiations.
Meanwhile, Iran’s Islamic Revolutionary Guard Corps intensified operations in the area by seizing two vessels in the Strait of Hormuz, accusing them of operating without the required permits and escorting them into Iranian territory.
The Strait of Hormuz remains one of the world’s most critical oil trade routes, and any prolonged disruption could have significant consequences for global energy markets.

Maradona’s daughter accuses medical team of “horrible manipulation” in court
One of the daughters of Diego Maradona testified in court this Tuesday, breaking down in tears as she denounced what she described as “absolute and horrible manipulation” by her father’s medical team, during an emotional hearing in Argentina.
Gianinna Maradona stated that she and her siblings agreed to home hospitalization after doctors presented it as the best option following the neurosurgery Maradona underwent on November 3, 2020.
The football icon died on November 25 of that year, and the ongoing trial seeks to determine whether the conditions of his home care were appropriate.
According to Gianinna, what the family found at the residence where Maradona was recovering did not match what had been promised. She testified that there was no adequate medical equipment, constant monitoring, or even an ambulance available, despite assurances of continuous care.
“The manipulation was absolute and horrible,” she said during the hearing in San Isidro, near Buenos Aires.
She accused members of the medical team, including neurosurgeon Leopoldo Luque, psychiatrist Agustina Cosachov, and psychologist Carlos Díaz, of misleading the family.
“I trusted these people, and all they did was manipulate us and leave my son without a grandfather,” she added.
Later in her testimony, recalling that six years have passed since her father’s death, she became emotional and said she struggled deeply with grief in the aftermath.
