H. floresiensis: A new species?

Asian island of Flores

Liang Bua where remains were found

Typical objects found. Tools and bones.

Artists rendering of H. floresiensis

Floresiensis and sapien skull

Comparison of size: Pygmy, European, and H. floresiensis

Pygmy elephant

Was floresiensis “smart”? What about the tools? Was floresiensis “smart”?

H. Sapien and H. floresiensis brain

Relative brain to body size

So…Several individual skeletons were found of a small population ranging in age from ~90,000 - 18,000 years ago. They have relatively small brains, but might have been able to do sophisticated things.

Homo floresiensis: Are they a distinct species, and if so, how are we related?

Trait diversity may vary in different populations 57” 65” 73”

Human Evolution

H. floresiensis: A new species?

Yes: the number of similar individuals, the dates of existence (~90,000-18,000 years old), and the different morphology.
