Comparison of size: Pygmy, European, and H. floresiensis
What about the tools? Was floresiensis “smart”?
The shape and size of the brain ofH. floresiensis indicates that it was organized differently than the brain of H. sapiens.
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?
Yes: the number of similar individuals, the dates of existence (~90,000-18,000 years old), and the different morphology.
There is much controversy over H. floresiensis Alternate hypotheses and rebuttals: Skeletons represent humans with brain damage. Skeletons represent humans with severe iodine deficiency:http://dsc.discovery.com/news/2008/03/05/hobbit-human.html Rebuttal to iodine deficiency: http://johnhawks.net/weblog/fossils/flores/cretin-flores-faq-2008.html Wrist bones are very different from humans:http://www.sciencemag.org/cgi/content/abstract/317/5845/1743
