The Unexpected Role of Early Humans

Anthropologists long believed Homo habilis was the first 'true' human species and the pioneer behind the earliest stone tools, known as the Oldowan Toolkit, found in Tanzania’s famed Olduvai Gorge. However, startling evidence has emerged showing that these early humans were likely hunted by leopards and other formidable predators.

Evidence of Predation Unearthed

Research indicates that as early as 1.85 million years ago, H. habilis was not only scavenging but also falling prey to powerful carnivores. By examining skeletons of two H. habilis individuals, scientists discovered telltale gnaw marks, which were once attributed to scavenging hyenas. But a revolutionary AI analysis identified these bite marks as belonging to leopards—with a staggering accuracy of over 90%. This revelation flips the long-held notion that H. habilis was at the top of their ecological pyramid.

Reassessing Early Human Superiority

Manuel Domínguez-Rodrigo, a lead author of the study, remarked on the implications of this finding: “For years, we've characterized H. habilis as the first dominant scavenger, adapting and thriving in an environment filled with carnivores. This research challenges that narrative, showcasing that instead, they were susceptible to predation much like their predecessors, the Australopithecines.

Who Truly Claims the Apex Predator Title?

With H. habilis's status as a formidable scavenger now questioned, the spotlight shifts to Homo erectus, a contemporaneous species allegedly better equipped for survival against threats like leopards. Researchers speculate that H. erectus, with its more ground-oriented lifestyle, may have developed defensive strategies that allowed it to ascend the evolutionary ladder and potentially even master the art of butchering hunted prey.

A Profound Shift in Understanding Human Evolution

This groundbreaking research not only illustrates the vulnerability of early humans but also challenges our understanding of the evolutionary journey toward becoming apex predators. As we grapple with these revelations, it raises the question: Who were the true trailblazers in the history of human survival?
