The Flores man’s disappearance may have finally been explained

Numerous questions surround the Flores man in the field of palaeoanthropology, many of which remain unanswered to this day. A recent study, however, offers a new approach that may fundamentally reshape our understanding of the fate of Homo floresiensis.

Homo floresiensis—known to both science and the wider public as the “hobbit”—has fascinated palaeoanthropologists for decades. The remains of this archaic human species, standing at only around one metre tall and exhibiting unusual anatomical features, were first discovered on the island of Flores in the early 2000s.

Since then, several theories have emerged suggesting that the Flores man might even still live among us today—although no convincing evidence has ever been found.

• Shocking discovery: Did the Flores man not go extinct after all?

A new multidisciplinary study now significantly refines the long list of mysteries surrounding the Flores man, presenting compelling evidence that climatic and environmental changes may have played a decisive role in the disappearance of the “hobbits”, reports Archaeology News.

Extensive analysis brings new insights

The research team examined a precisely dated stalagmite sample from the Liang Luar cave, located near Liang Bua. By analysing magnesium–calcium ratios and oxygen isotopes within the calcite layers, the researchers were able to reconstruct ancient rainfall levels and seasonal fluctuations in precipitation.

The results paint a dramatic picture: between 76,000 and 61,000 years ago the island’s annual average rainfall dropped by roughly 37%, followed by periods of extremely severe summer droughts.

The Flores man’s main prey fell victim to the drought as well

The decreasing rainfall not only had a devastating impact on human communities but also on key species within the island’s ecosystem. One of the “hobbits’” most important prey animals was Stegodon florensis insularis—a species similar to modern elephants but much smaller.
