Revising the Image of Homo floresiensis
An international team of scientists led by researchers at the Smithsonian National Museum of Natural History has presented analysis results that completely undermine previous notions about the behavior of Homo floresiensis. It turns out that this species, first discovered in 2003 on the Indonesian island of Flores, did not hunt large animals and could not produce fire; its lifestyle was more akin to that of scavengers. It is notable that the height of these ancient hominids was only about 109 cm, and their brain volume was roughly three times smaller than that of modern humans.
The lead researcher, Dr. E. Grace Witczak, explained that previous hypotheses about the advanced behavior of 'hobbits' were based on supposed evidence of fire use and hunting large game. However, a new analysis of nearly 3,100 fragments of stegodont bones and around 7,000 rodent remains revealed a different picture. As Dr. Witczak noted,
'Initially, Homo floresiensis was described as a species with relatively complex behavior, despite its short stature and small brain, based on allegedly existing evidence of fire usage and hunting large animals.'
Unexpected Results of the Analysis
The researchers found that cut marks left by Homo floresiensis tools mainly appear on the less valuable parts of the skeleton — ribs, finger phalanges, cranial fragments, and vertebrae. Of the thousands of stegodont bones, only one rib bore signs of fire exposure. In contrast, nearly 20% of mouse bones associated with Homo sapiens were burned. However, among over 4,200 rodent remains from deposits linked to Homo floresiensis, there were no signs of burning. This clearly indicates that the 'hobbits' did not possess the technology of fire-making.
As early as 2017, researchers from Flinders University in Adelaide (Australia) challenged the theory of Homo floresiensis originating from Homo erectus. Anatomical features indicated that this species was closer to Homo habilis, which lived from 2.1 to 1.5 million years ago. The authors then emphasized:
'Homo floresiensis was initially described as a species capable of complex cognition and behavior, partly because it was considered an isolated island dwarf branch of Homo erectus. However, over time, evidence of behavioral complexity, including tool use and fire, significantly weakened.'
Thus, the new research fundamentally changes the understanding of the lifestyle of Homo floresiensis: it is now clear that they were scavengers, not hunters, and did not know how to handle fire. These findings prompt a reevaluation of many previous theories.
The results of this work are important not only for understanding hominid evolution but also for realizing that small stature and brain volume do not necessarily imply primitive behavior. The study of 'hobbits' helps scientists better understand how human ancestors adapted to life in isolation and with limited resources. Moreover, this research serves as a reminder that scientific theories must be constantly tested and corrected as new data emerges.
