Homo floresiensis

Homo floresiensis, also called "Flores Man" or "Hobbit" (after the fictional species), was an extinct small type of early human that lived on the island of Flores, Indonesia. These tiny humans lived there until around 50,000 years ago when modern humans arrived.

In 2003, scientists found the bones of one of these people in a cave named Liang Bua. This person was about 1.1 meters tall, which is roughly 3 feet and 7 inches. Since then, scientists have found bones from 15 of these individuals, including one full skull named "LB1".

Scientists think the ancestors of Homo floresiensis came to Flores about 1.27 to 1 million years ago. The small size of these humans is thought to be because of a process called insular dwarfism, where animals on islands become smaller over time. There has been discussion about whether they were a smaller version of Javanese Homo erectus or from an earlier group of humans like Australopithecus or Homo habilis.

Originally, it was thought that Homo floresiensis might have lived until just 12,000 years ago, but newer research shows they lived between 60,000 and 100,000 years ago. Tools made of stone found near their bones are from 50,000 to 190,000 years old. Even older bones from a place called Mata Menge are about 700,000 years old.

Specimens

The first specimens of Homo floresiensis were found on the island of Flores in Indonesia in 2003 by archaeologists. They discovered a nearly complete skeleton of a small person, about 1.1 meters tall, in Liang Bua cave. This skeleton, called LB1, was identified as a new species and named Homo floresiensis. More skeletons were found in later digs.

Scientists discussed the discovery, with some wondering if it was a new species. Some of the fossils were damaged during a disagreement about their study. Even so, the findings gave us important information about small, ancient humans who lived on Flores alongside modern humans until around 50,000 years ago.

Classification and evolution

Because of the deep neighbouring Lombok Strait, Flores stayed an isolated island during times when sea levels were low. Because of this, the ancestors of H. floresiensis could only have reached the island by oceanic dispersal, most likely by rafting. The oldest stone tools on Flores are around 1 million years old.

In 2016, fossil teeth and a partial jaw from early humans thought to be ancestors of H. floresiensis were found at Mata Menge, about 74 km (46 mi) from Liang Bua. They are about 700,000 years old. There are two ideas about where H. floresiensis came from. One idea is that H. floresiensis came from a very early group of small, simple humans who left Africa before 1.75 million years ago. The other idea is that H. floresiensis came from a group of Javanese Homo erectus who got stuck on Flores, and their small size is because of insular dwarfism, a change that happens to animals on islands. As of 2025, most scientists agree with the insular dwarfism idea.

Anatomy

Homo floresiensis, also called the "Flores Man" or "Hobbit," had a very small body and a small brain. Scientists found these ancient humans were much shorter than humans today. One example was about 1.06 meters tall, about the height of a young child. They weighed about 25 kilograms and lived on the island of Flores in Indonesia.

Their brains were tiny, about one-third the size of a modern human’s brain. Even so, they showed clever skills like making tools and using fire. This suggests their brains worked in special ways. Their arms and legs were shorter and more flexible, giving them a unique way to move. These features help scientists learn how humans changed to live on a faraway island thousands of years ago.

Culture

Scientists found many stone tools in the cave where Homo floresiensis lived. These tools include pieces called lithic flakes and small blades known as microblades. Some researchers think these early humans learned to make tools from an older human species called H. erectus.

These tools were often found near bones of a large, extinct animal related to elephants, called Stegodon florensis. This has led some to believe that H. floresiensis may have hunted young Stegodon. Others think they might have mostly eaten large rats, like Papagomys, which were also found in the cave. There was also a big dragon-like lizard called the Komodo dragon on the island, which may have competed with H. floresiensis for food.

Paleoecology

Flores Island was home to an ancient human species called Homo floresiensis. The island had a special ecosystem with few large animals. It had a small elephant relative named Stegodon florensis, several types of rats, and large birds such as a giant stork and a vulture. The island also had the famous Komodo dragon and another smaller monitor lizard.

Extinction

Scientists think the last Homo floresiensis lived about 60,000 years ago. We know this from bones found in a cave on the island of Flores in Indonesia. Around that time, modern humans arrived in the area. This may have made it hard for these smaller ancient humans to survive.

Studies also show that the climate changed at about the same time. It became drier and there was less fresh water. This made it harder for H. floresiensis to find food and water in the cave.

"Hobbit" nickname

Main article: Hobbit (word) § Proprietary status

Homo floresiensis was called "the hobbit" by the people who found it. They chose this name because it reminded them of the small people from J. R. R. Tolkien's book The Hobbit.

Later, a scientist could not use the word "hobbit" when talking about this ancient human. This was because of legal problems. A movie studio also wanted to make a film called Age of the Hobbits, but they had to change the name because of the same legal issues. The movie was finally shown with a new title, Clash of the Empires.
