Almost 2 million years ago, leopards may have hunted early humans in East Africa, according to a new study. Researchers used artificial intelligence to shed light on the fate of two Homo habilis individuals, an early human species.
Previously, scientists suspected that H. habilis could have been preyed upon by large carnivores like big cats and crocodiles. However, identifying the specific predators from fossil evidence has been difficult. Traditional methods often fell short, leaving many questions unanswered.
A team, led by Manuel Domínguez-Rodrigo from the University of Alcalá, utilized AI for their recent research published in the Annals of the New York Academy of Sciences. The AI provided a clearer picture of what happened to two key fossils—known as OH 7 (a juvenile) and OH 65 (an adult)—carefully preserved at the Olduvai Gorge in Tanzania.
Domínguez-Rodrigo noted the AI made astonishing strides in identifying bite marks. Their system accurately pinpointed the marks were made by leopards, indicating that these individuals were more than just attacked; they were likely consumed.
Statistically, the AI models achieved over 90% accuracy in identifying the carnivorous creatures responsible for the bite marks. This advancement in technology signifies a significant leap in the study of ancient predation, which could bring fresh perspectives on early human life and survival.
The evidence of severe skeletal damage reinforces that these H. habilis individuals faced a brutal end. As Domínguez-Rodrigo explained, if other predators had feasted on them first, very little skeleton would have remained for leopards to consume. This suggests that leopards were indeed the final predators, demonstrating a predation pattern that is both fascinating and horrific.
Moreover, this research highlights how using AI tools in paleontology can enhance our understanding of ancient ecosystems. The ongoing relationship between early humans and their predators paints a vivid picture of survival struggles in a world filled with danger.
Overall, the study not only confirms the role of leopards in the demise of these early humans but also showcases the potential of modern technology in uncovering the complexities of our past. As we look ahead, the implications for both archaeology and artificial intelligence continue to grow, opening exciting avenues for future discoveries.
