What is Homo floresiensis?
Homo floresiensis is the taxonomic name for an extinct hominin that lived on the island of Flores in Indonesia, possibly as recently as 12,000 years ago. The species' origins are not fully understood; some evidence suggests they descended from modern humans (Homo sapiens), while other evidence indicates they descended from a different species within the genus Homo.
Remains found in the Liang Bua cave in 2004 indicated that H. floresiensis stood approximately 100 cm (40 inches) tall and had a small skull. Due to their small stature, they were nicknamed "hobbit-like". Fossils attributed to H. floresiensis have been dated to between 100,000 and 60,000 years ago. Some scientists suggest modern humans may have driven H. floresiensis to extinction.

Where were the remains of Homo floresiensis discovered?
The remains of Homo floresiensis, an extinct hominin species, were discovered in the Liang Bua cave on Flores, an island in Indonesia. In 2004, a team of Australian and Indonesian anthropologists found skeletal remains of an adult female and other individuals. Flores is part of the Lesser Sunda Islands.
The fossils and surrounding rocks have been dated to between 100,000 and 60,000 years ago. The diminutive size of Homo floresiensis led to the nickname "hobbit-like," inspired by J.R.R. Tolkien's short-statured race.

How did Homo floresiensis get the nickname "the Hobbit"?
Homo floresiensis earned the nickname "the Hobbit" due to its extremely short stature. The remains of a prehistoric woman, discovered on Flores Island in 2003, stood only about 100 cm (40 inches) tall. This diminutive size reminded researchers of the hobbits, a race of small, human-like creatures in J.R.R. Tolkien's novels. The nickname quickly gained popularity, reflecting public curiosity about this unique and diminutive human species.

What did scientists find unusual about the size and features of Homo floresiensis?
Homo floresiensis, an extinct hominin discovered on the island of Flores, Indonesia, exhibited unusual characteristics that intrigued scientists.
The skeletal remains of an adult female revealed a height of only about 100 cm (40 inches) and long arms. Its skull had a cranial capacity of only 380 cc, comparable to a modern chimpanzee. Despite the small brain size, H. floresiensis fashioned a stone tool industry similar to that of early Homo species and lived among giant rats, dwarf elephants, and Komodo dragons from at least 38,000 years ago to about 18,000 years ago.
These features differ significantly from the general trend of increasing stature and brain size observed in other members of the human family.

When did Homo floresiensis live compared to other early humans?
Homo floresiensis, an extinct hominin species, lived on the island of Flores in Indonesia until approximately 12,000 years ago. Discovered in 2004, H. floresiensis stood about 40 inches tall, with a small brain capacity.
The oldest known Homo sapiens remains date back roughly 315,000 years. Homo naledi lived around 300,000 years ago. Modern humans migrated to Southeast Asia and Australia around 50,000 years ago, and to Flores around 11,000 years ago. Some scientists suggest modern humans may have caused the extinction of H. floresiensis. The exact origins of H. floresiensis remain a mystery; some researchers propose it was a sister species to H. habilis.

Why is the discovery of Homo floresiensis important for our understanding of human evolution?
The discovery of Homo floresiensis, an extinct hominin species that lived on the Indonesian island of Flores, is important because it shows that the human lineage is more diverse than previously thought. H. floresiensis stood approximately 40 inches tall and had a brain size comparable to that of a modern chimpanzee.
The origins of the species are not fully understood; some evidence suggests that H. floresiensis descended from modern humans (H. sapiens), and other evidence supports the notion that H. floresiensis descended from a different species within the genus Homo. Stone tools and possible evidence that H. floresiensis used fire have been discovered. Some scientists acknowledge that modern humans could have driven H. floresiensis to extinction.

Homo floresiensis, taxonomic name given to an extinct hominin (member of the human lineage) that is presumed to have lived on the Indonesian island of Flores as recently as 12,000 years ago). The origins of the species are not fully understood. Some evidence suggests that Homo floresiensis descended from modern humans (H. sapiens), and other evidence supports the notion that H. floresiensis descended from a different species within genus Homo.
Skeletal remains of an adult female and other individuals were found at the Liang Bua cave on Flores in 2004 by a team of Australian and Indonesian anthropologists. An initial analysis of the remains indicated that H. floresiensis stood only some 100 cm (40 inches) tall and had long arms and a skull with a cranial capacity of a mere 380 cc, comparable to that of a modern chimpanzee, yet the delicate skeletal bones, nonprojecting face, and reduced dentition placed them squarely within the human family. On the basis of these findings, the hominin’s discoverers classified it as a distinct species of genus Homo and theorized that it may have descended from H. erectus, a much older and larger hominin that may also be the ancestor of modern humans.
They further hypothesized that the diminutive size of H. floresiensis may have been caused by island dwarfing, or endemic dwarfing, a process whereby some creatures confined to isolated habitats such as islands are known to have become smaller over time. Such dwarfing has never been seen in the remains of other members of the human family, which show that stature and brain size have generally increased from the earliest hominins up to modern humans. Other scientists, who have examined the remains, contend that they belong to a member of Homo sapiens with features consistent with a modern human with Down syndrome.

Public curiosity about the new species abounded, and, in homage to a short-statured race in J.R.R. Tolkien’s novels, it was soon dubbed “hobbit-like.” However, the initial analysis of the find and the dwarfing hypothesis were immediately challenged by the scholarly community. Some subsequent examinations of the remains contradicted the original conclusions, suggesting instead that they represent a population of modern humans that was quite gracile (slender) but of normal height. In contrast, other investigations, which compared the specimen’s gait, foot size, and skull size with that of modern humans, suggested that the remains belong to a new species, perhaps one that descended from an ancestor more primitive than H. erectus.
Subsequent investigations into the remains of H. floresiensis cast doubt on whether the species descended from modern humans. Fossils attributed to H. floresiensis and the rocks that bore them have been dated to between 100,000 and 60,000 years ago, but modern humans did not arrive in Southeast Asia and Australia until 50,000 years ago—and not at Flores until about 11,000 years ago. Such a mismatch in time and place would seem to indicate that H. floresiensis descended from another species within Homo. Although the true origin of H. floresiensis remains a mystery, some scientists do acknowledge that modern humans could have driven H. floresiensis to extinction.
