Homo floresiensis, commonly called "hobbits"

a. Seem too primitive to have developed water-going capability.
b. All died out before 12,000 years ago.
c. Could not have evolved from Homo erectus, judging from their brain size.
d. Had brains no larger than chimpanzees or australopiths, but evidently were capable of building rafts and functional tools.

Final answer:

Homo floresiensis, or 'hobbits', were small but advanced humans who used tools and fire, challenging the link between brain size and intelligence. They likely evolved from larger Homo erectus through the process of island dwarfism. Their capabilities and adaptation provide a unique insight into human evolution.

Step-by-step explanation:

Homo floresiensis, commonly referred to as "hobbits", has intrigued scientists since its discovery. Despite their small size and brain, evidence suggests these archaic humans had advanced capabilities such as making stone tools, using fire, and possible construction of watercraft. Interestingly, Homo floresiensis may have evolved from Homo erectus populations that experienced island dwarfism, an evolutionary process common in island environments due to limited resources and lack of predators.

Island Dwarfism and Evolution

The idea of island dwarfism explains the small stature and brain size of Homo floresiensis. Instead of a sign of lesser intelligence, this was an adaptation to the island's unique ecological niche, possibly allowing for a preserved brain-to-body ratio through neurological reorganization. The evidence of complex behaviors performed by H. floresiensis challenges the notion that brain size is the sole indicator of capability in hominin species.

Tool Making and Adaptation

The legacy of H. floresiensis shows that despite a brain size comparable to earlier hominins and even some primates, their skillset included tool making and possibly raft building. Their discovery alongside a species of dwarf elephant known as Stegodon adds credence to the theory of island dwarfism affecting multiple species.
