How Early Hominids Hunted and Ate Prehistoric Elephants to Survive

Evidence from Olduvai Gorge in Tanzania indicates that human ancestors butchered and consumed prehistoric elephants 1.8 million years ago, a dietary habit that provided the necessary energy to fuel the evolution of larger brains.

The discovery at the site known as EAK suggests that early hominids were engaging with megafauna—animals weighing more than 1,000kg—substantially earlier than the previous estimate of 1.5 million years ago.

The animals targeted were Elephas (Paleoxodon) recki, a prehistoric species that roamed Tanzania nearly two million years ago and reached sizes nearly twice that of a modern African elephant, which can weigh up to 6,000kg.

Nutritional Impact on Brain Evolution

The consumption of these massive animals provided a dense source of nutrients and calories. This high-energy diet is linked to the biological demands of developing and maintaining larger brains in early human ancestors.

The ability to process such large amounts of meat allowed early hominids to survive in challenging environments and supported the metabolic costs associated with increased cranial capacity.

Strategic Hunting and Tool Production

Parallel research conducted by Professor Ran Barkai and Dr. Meir Finkel from Tel Aviv University highlights the strategic nature of these hunting activities. Their study of Paleolithic stone quarries in Israel’s Upper Galilee region, dating back almost 2 million years, reveals that early humans specifically positioned their tool-making hubs to facilitate elephant hunting.

These quarries served as centers for crafting flint tools essential for the butchery of elephants, which were a primary food source for Homo erectus.

The researchers found that these sites were strategically located along elephant migration routes and near water sources. Dr. Finkel noted that An elephant consumes 400 liters [105 gallons] of water a day, on average, and that’s why it has fixed movement paths, making the banks of streams, rivers, and lakes ideal locations for tracking prey.

Broader Evolutionary and Ecological Effects

The relationship between early humans and proboscideans had significant ecological consequences. An AI-assisted analysis of fossil records indicates that the extinction rate of elephant-like species increased five-fold following the evolution of early humans approximately 1.8 million years ago.

This suggests that human hunting activities played a substantial role in the decline and eventual extinction of numerous proboscidean species over the last two million years.

The pattern of hunting megafauna continued long after the era of Homo erectus. Records show that Neanderthals also hunted and butchered massive elephants 125,000 years ago, securing large quantities of meat capable of feeding hundreds of individuals.

• The discovery at Olduvai Gorge pushes the timeline of megafauna consumption back to 1.8 million years ago.
• The prehistoric elephant species Elephas (Paleoxodon) recki provided critical caloric intake for brain growth.
• Homo erectus utilized strategic flint quarries near water sources in Israel to facilitate hunting.
• Human hunting is linked to a five-fold increase in the extinction rate of elephant-like species starting 1.8 million years ago.
