Peter Brown of the University of New England in Australia, who leads the team that's examining the bones, says it was a major surprise to find tools, including points and hafted microblades, associated with homo floresiensis, as the new human family member has been named. The tools are like those previously seen only with European fossils from our own species, Homo sapiens, Brown notes, and the oldest of them were made 94,000 years ago. Homo sapiens is thought to have arrived in the region a mere 40,000 years ago, much too late to be responsible for the implements. If this tiny human made the tools, then the internal structure of its brain must have been more like our own than a chimp's, despite being just a third the size of ours. Of the six species of humans known, all extinct except ours, this is by far the smallest-brained human scientists have ever seen.
