Studies Reveal New Information About Homo Floresiensis, Known as “Hobbit People,” and Their Extinction Is Not Linked to Homo Sapiens
The hobbits, or Homo floresiensis, became famous in popular culture due to the universe created by J. R. R. Tolkien in his works “The Lord of the Rings” and “The Hobbit.” However, the true story of the hobbits is much more intriguing. Researchers believed that this species of hominid had gone extinct due to competition with Homo sapiens.
However, a new study, still awaiting peer review and published in EarthArXiv, suggests that this narrative may be wrong, according to olhardigital.
The Hobbit People and Their Relationship with Humans
According to information from IFLScience, Homo floresiensis inhabited the island of Flores in Indonesia about 50,000 years ago. They earned the nickname “hobbit people” due to their short stature and appearance resembling small gnomes.

A discovery in a cave in Israel rewrote human history: 110,000 years ago, Neanderthals and Homo sapiens were not rivals, they shared tools, buried their dead with the same rituals, and lived as one community.
The new study revealed that archaeological records of the hobbits disappeared about four millennia before humans arrived in the region, which happened approximately 46,000 years ago. This indicates that hobbits never coexisted with Homo sapiens.
Causes of Hobbit Extinction
To understand what led to the extinction of Homo floresiensis, researchers analyzed the proportions of magnesium, calcium, and oxygen isotopes in rocks near the archaeological site of Liang Bua, a cave on the island of Flores. This study allowed for the reconstruction of the region’s paleoclimatic changes over time.
The results indicate that the extinction of hobbits may have been triggered by climate changes, particularly the extinction of the dwarf elephants known as Stegodon, which hobbits depended on for food.
About 76,000 years ago, when the elephants and Homo floresiensis coexisted, annual rainfall was high and reliable. However, in the 20,000 years that followed, rainfall levels dropped dramatically, becoming less predictable and reaching a historic low about 50,000 years ago.
Possible Scenarios for Extinction
Researchers presented two plausible scenarios to explain the extinction of hobbits.
The first suggests that the dwarf elephants may have remained in the area and died en masse due to water scarcity caused by aridification and hunting by the hobbits, leading to the species’ extinction.
The second scenario proposes that the elephants migrated to other areas in search of more favorable conditions, while the hobbits may have followed the animals.
In this process, it is possible that Homo floresiensis encountered Homo sapiens, which does not rule out the possibility that humans contributed to the end of the species.
Curiosities About Hobbits
These new discoveries significantly change the understanding of hobbits and their extinction, highlighting the importance of climate changes rather than competition with humans.
This information not only enriches the story of Homo floresiensis, but also brings to light fascinating curiosities about the diversity of hominids that inhabited our planet.
The discovery about hobbits reminds us that the history of human evolution is complex and full of nuances.
