New Study Reveals Homo floresiensis Likely Not a Big-Game Hunter
The tiny ancient human species Homo floresiensis, also known as the ‘Hobbit’, discovered on Flores Island, has long puzzled scientists due to suspicions that they were capable of creating complex tools, using fire, and hunting large animals despite their small brain size.
However, a new study published in the journal Science Advances has successfully dismantled long-held assumptions regarding the impressive intelligence of these ‘Hobbit’ humans.
Shortly after the discovery of Homo floresiensis in 2003 at Liang Bua Cave, researchers found scratch marks on fossils of Stegodon, a dwarf relative of the elephant roughly the size of a cow. These fossils were buried in the same soil layer as stone tools belonging to the Hobbit humans.
At the time, many concluded that these bones were evidence of Hobbit dietary remains, based solely on the fact that the bones and stone tools were found together in the same location.
To test this hunting theory, Elizabeth Grace Veatch, a paleoanthropologist from the University of Tübingen, conducted an in-scale analysis which instead showed that Komodo dragons had preceded the Hobbits in competing for the island’s largest prey.
The research team compared Komodo dragon bite marks with scars on the Stegodon bone fossils. The results showed that Komodo bite marks were concentrated in meat-rich areas such as the shoulder and hip, indicating that the reptiles arrived at the carcass first.
In contrast, cut marks from Hobbit stone tools were only found on less meaty parts, such as the legs and ribs. This reality surprised researchers who initially believed all scratches on the bones were man-made.
This evidence suggests that Hobbit humans likely acted only as passive scavengers, searching for food scraps left behind by Komodo dragons.
These findings indicate that they were not as intelligent as previously assumed, as hunting large animals—which requires cooperation and meticulous planning—is usually associated only with large-brained species such as Homo sapiens and Neanderthals.
The study also refutes the assumption that Hobbit humans had mastered the use of fire. Previously, the presence of charcoal and burnt animal bones in Liang Bua Cave was considered evidence of Hobbit domestic activity.
However, after a re-examination of the ancient soil layers within the cave, which cover the period between 774,100 and 60,000 years ago, all evidence of fire use was found to originate from much younger soil layers, dating to when Homo sapiens began occupying the cave after the extinction of Homo floresiensis and Stegodon.
While the depiction of the Hobbit’s behavioural intelligence is now more simplified, this discovery in no way diminishes the value of their successful adaptation to the wild.
The fact that this small-brained species was able to survive on an isolated island for almost one million years, facing extreme environmental challenges and living alongside formidable predators like Komodo dragons, is an extraordinary evolutionary achievement.
Veatch emphasised that the ability to survive while isolated on an island for 50,000 years without a dependence on fire or the ability to hunt large animals demonstrates how remarkable their method of adaptation truly was.
