Early humans were prey, not predators, study finds....

For decades, textbooks painted a dramatic picture of early humans as tool-using hunters who rose quickly to the top of the food chain. The tale was that Homo habilis, one of the earliest representatives of our genus, was one of the first predators to dominate predators and lead humans down the path toward being top predators.

But new research that applies artificial intelligence indicates this ascent to power was much slower, more complicated, and much riskier than previously thought.

Research findings suggest that Homo habilis was not yet in control of its world 2 million years ago. Instead, the small-brained humans were still preyed upon, probably by leopards. That is, our ancestors remained vulnerable much longer than scientists have believed.

The evidence comes from bones uncovered at Tanzania's Olduvai Gorge, a site that has yielded some of the most important human origins clues.

Anthropologists previously believed the markings on those bones were caused by tool use or scavenging. But the team led by Manuel Domínguez-Rodrigo, an anthropologist at Rice University and co-director of Madrid's Institute of Evolution in Africa, wanted to test that assumption with new technology.

They taught machines in the guise of deep-learning algorithms to recognize the subtle tooth mark patterns of different carnivores. They supplied the system with thousands of samples, which learned to tell bites produced by lions, hyenas, wolves, crocodiles, and leopards apart.

When the AI scanned Homo habilis fossils at Olduvai, the findings were dramatic. "We found that these early hominids were consumed by other carnivores rather than taking over the landscape at the moment," Domínguez-Rodrigo explained. The leopard signature appeared repeatedly with strong confidence.

This find disrupts the traditional narrative. Researchers, for many years, believed that around 2.5 million years ago, humans were capable of outsmarting large felines and hyenas by using stone implements and collective action. That would have been a transition from prey to predator.

But the bites have a different story to tell. Homo habilis, even though its brain was in development and it was making increasing use of tools, remained on the menu almost a half-million years later. "The origin of the human brain doesn't mean we knew everything right away," Domínguez-Rodrigo said. "This is a more nuanced tale. These early humans, these Homo habilis, were not the ones to effect that change."

Instead, the researchers suggest that the power balance shifted much more unevenly and gradually than was thought. Maybe it was Homo erectus, which existed alongside habilis, that played a larger role in the rise of human hunting dominance.

What's new in this study is not so much the finding as the method. For many years, human scientists have simply looked at fossil bones, noting scratches, fractures, and dents and trying to decide whether the injury was caused by tools, predators, or natural forces. But where various predators leave corresponding tooth markings has always been a hypothesis.

Artificial intelligence flipped that on its head. Deep learning algorithms can now detect microscopic patterns that most scientists can't see and not only assert a predator was involved but which predator was involved. "AI is a game changer," Domínguez-Rodrigo said. "It's taking approaches that have been stable for 40 years past what we thought. For the first time, we can determine not only that these people were eaten but by whom."

It is now possible to associate bones with specific predators. Scientists are able to go back to collections of fossils from across Africa and the world to solve questions long in the making: When did hominids stop being prey? Where did they first become lords of their landscapes? Which predators were most deadly?

[Defense of Ukraine @DefenceU]

President @ZelenskyyUa: It is time to end this war. But Russia’s ruler wants to keep fighting. That is why Ukrainian sanctions against this aggression are working. Last night, our drones covered a distance of about 1,000 kilometers to the St. Petersburg region – to the enemy navy’s arsenals and a base in Kronstadt. Our long-range sanctions also reached about 500 kilometers into the Krasnodar region – and hit an oil depot. These are important results of the joint efforts by warriors from the Armed Forces of Ukraine, the Security Service of Ukraine, and the Defense Intelligence of Ukraine. Russia must end its war and stop its attacks on life. Any manifestation of injustice against Ukraine will receive a just response. I thank our warriors for their precision.

La Fiscalía General de la Nación presentó ante un juez de control de garantías a Ronald Camilo Vera Pulido, Pedro Alexis Téllez Ariza y Carlos Anderson Méndez Pulido, presuntos integrantes de un grupo delincuencial dedicado al secuestro de conductores de plataformas digitales de transporte y al hurto de sus pertenencias y vehículos en Bogotá.

Según la investigación, los procesados creaban perfiles falsos para solicitar servicios de transporte hacia determinados sectores de la ciudad. Una vez abordaban el vehículo, presuntamente sometían a la víctima mediante el uso de armas de fuego y cortopunzantes, obligándola a ubicarse en la parte trasera para inmovilizarla.
