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.”

Guatemala considers sending high-risk gang members to military prisons

Amid the escalating crisis in Guatemala’s prison system, the government is considering transferring high-risk gang members to military-run detention facilities, a move that analysts say could help address overcrowding and the lack of control in civilian prisons.

The debate has gained urgency following the killing of ten police officers by gang members, reportedly in retaliation after the government refused to meet demands made by Aldo Dupie Ochoa, alias “El Lobo,” leader of the Barrio 18 gang, which authorities identified as responsible for the attack.

Guatemala’s Minister of Defense, Henry David Sáenz, told local media that the possibility of relocating high-danger inmates to military brigades has not been formally discussed. However, he noted that the practice is not new to the Armed Forces and said it is something that “was already being done.”

One example is the detention center located within the Mariscal Zavala Military Brigade, in Zone 17 of Guatemala City, where several inmates are held under military supervision. The facility also houses high-profile detainees, including former official Eduardo Masaya, who faces corruption charges.

In 2015, a ministerial agreement authorized the establishment of the Zone Seventeen Detention Center within the brigade, with a maximum capacity of 114 inmates in Area A and 21 in Area B. The agreement specified that the facility would be used exclusively for civilians or military personnel considered at risk of assassination.

Additionally, since 2010, a prison has operated within the Matamoros Barracks in Zone 1 of Guatemala City, holding dangerous or high-profile inmates. However, media outlets have described these military detention centers as “VIP prisons,” particularly for former government officials such as ex-president Otto Pérez Molina.

Rights group says over 5,000 killed in Iran protests, mostly civilians

A U.S.-based human rights group said on Friday it has confirmed that more than 5,000 people were killed during the recent protests in Iran, most of them civilians allegedly shot by security forces.

Non-governmental organizations monitoring the toll from the crackdown on what have been described as the largest demonstrations in Iran in years said their work has been hampered by an internet shutdown imposed by authorities since January 8. They warned that the actual death toll is likely significantly higher.

The Human Rights Activists News Agency (HRANA), based in the United States, reported on Friday that it had verified the deaths of 5,002 people, including 4,714 protesters, 42 minors, 207 members of the security forces, and 39 bystanders.

The group added, however, that it is still investigating an additional 9,787 possible deaths, underscoring the difficulty of independently confirming information amid ongoing restrictions and repression.

Japan reopens Kashiwazaki-Kariwa Plant despite public concerns

La centrale nucléaire japonaise de Kashiwazaki-Kariwa, la plus grande au monde, a repris ses activités mercredi pour la première fois depuis la catastrophe de Fukushima en 2011, malgré les inquiétudes persistantes d’une partie de la population.

La remise en service a eu lieu à 19h02 heure locale (10h02 GMT), a indiqué à l’AFP Tatsuya Matoba, porte-parole de la compagnie Tokyo Electric Power (Tepco).

Le gouverneur de la préfecture de Niigata, où se situe la centrale, avait donné son feu vert à la reprise le mois dernier, en dépit d’une opinion publique divisée. Selon une enquête menée en septembre par la préfecture elle-même, 60 % des habitants se déclaraient opposés au redémarrage, contre 37 % favorables.

Mardi, plusieurs dizaines de manifestants ont bravé le froid et la neige pour protester près de l’entrée du site, sur les rives de la mer du Japon.

« L’électricité de Tokyo est produite à Kashiwazaki. Pourquoi seuls les habitants d’ici devraient-ils être exposés au danger ? Cela n’a aucun sens », a déclaré à l’AFP Yumiko Abe, une riveraine de 73 ans.

La centrale de Kashiwazaki-Kariwa avait été mise à l’arrêt lorsque le Japon a fermé l’ensemble de ses réacteurs nucléaires à la suite du triple désastre de mars 2011 — un séisme, un tsunami et un accident nucléaire — survenu à Fukushima.
