The discovery of a 100,000-year-old site in Ethiopia's Afar Rift has revealed a treasure trove of information about early human life and behavior. This site, known as Halibee, offers a rare glimpse into the daily rhythms of life and death, challenging our understanding of human migration and behavior during the Middle Stone Age. What makes Halibee truly remarkable is the preservation of an unusually complete record of daily life and death, unlike many African sites that only preserve fragments in caves.
The site, located in a floodplain, was repeatedly used by early humans, providing a unique opportunity to study their behavior and interactions with the environment. Archaeologist Yonas Beyene of the French Center for Ethiopian Studies (CFEE) documented the site, revealing a wealth of information about stone tool production, animal bones, and human remains.
One of the most fascinating aspects of Halibee is the evidence of repetitive, short visits by early humans. The tools found at the site were seemingly both made and discarded during brief returns to the floodplain, indicating a mobile way of life. This challenges the traditional view of early humans as nomadic hunter-gatherers, suggesting a more complex and varied lifestyle.
The site also provides clues to human movement and exchange. Only a few tools were made from obsidian, volcanic glass that snaps into sharp edges, even though Halibee itself lacks that material. This suggests that the obsidian was imported from elsewhere, indicating a network of trade and exchange among early human groups.
The animal bones found at Halibee also provide valuable insights into the diet and environment of early humans. The presence of monkeys, rodents, and medium-sized hoofed animals suggests a varied diet, while the absence of giraffes, birds, reptiles, and large carnivores indicates a more limited range of resources.
The human remains found at Halibee are also intriguing. One partial skeleton seems to have slipped quickly beneath sediment, avoiding the tooth marks and weathering common on exposed remains. This suggests a rapid burial, which can happen when flood sediment seals a body fast, cutting off scavengers and slowing damage from sun and trampling.
Another individual survived only as a tooth and small bone pieces cracked, darkened, and broken by intense heat. This evidence of burning at that temperature changes bone color and structure, suggesting the possibility of intentional cremation. However, the evidence remains hard to pin down, leaving fire as a clue without a clear cause.
Overall, Halibee provides a unique and comprehensive view of early human life and behavior, challenging our understanding of human migration and behavior during the Middle Stone Age. The site's preservation of an unusually complete record of daily life and death, along with the evidence of repetitive, short visits and trade and exchange networks, offers a fascinating glimpse into the past.
