Extinction: Homo floresiensis

48,000 BCE
58,000 to 48,000 BCE

Discovered in 2003, Homo floresiensis (also known as the “Hobbit”) inhabited the island of Flores in Indonesia from 190 to 50 thousand years ago. Humans arrived about 50,000 years ago and may be the reason for their extinction.

Lineage: Most likely not a Homo heidelbergensis, but a descendant species from an earlier ancient human. Perhaps from the very successful Dmanisi people, an Asian Homo erectus lineage, or perhaps even directly from Homo habilis, which might be the original Earth roamer. The link to Homo habilis is speculative and based on the smaller brain size and stature of the floresiensis people.

Imagined Image: A small group of Homo floresiensis in their natural habitat on the island of Flores, engaging in daily activities around a communal fire and interacting with the local fauna. This scene captures their unique adaptations and social behaviors within a lush volcanic landscape.

Survival: From about 190,000 BCE to 50,000 BCE, primarily on the island of Flores, Indonesia.
Size: Approximately 3’6″ to 3’10″ (a bit shorter than the pygmy in Africa at 4’11”).
Brain Size: 380 to 420 cm³.
Brain to Body Encephalization Quotient (EQ): Research ongoing, but roughly 3.2 (habilis=3.3 to 3.8; humans=7.4 to 7.8).
