They were able to say that these tools from different
time periods all bore striking similarities, suggesting that they were
made in the same way by a long lineage of ancient humans. It was
basically the same technology. That suggested a continuing tradition
of tool-making on the island over many hundreds of thousands of years.
The report's authors believed that the Hobbit inherited
tool-making skills from ancestors who lived on the island from about
800,000 years ago.
The tools themselves were quite simple, according
to Dr Brumm. The hominids were basically striking pieces of stone
off volcanic cobbles. It was a very simple manufacturing process.
The implements may have been used to process plants for food, slash
animal skins, or carve wooden tools, although no one was entirely
The 2006 data was unlikely to convince all scientists,
however, not least because there existed a very long time gap between
those tools which were forged some 800,000 years ago, and those found
at Liang Bua. Thanks to the large time gap it couldn't be guaranteed
that this material really was related.
However, it did reinforce the argument that the
Hobbit really is a descendant of a population that had lived on the
island for a very long time. This potentially allowed enough time for
the unusual features of the Hobbit to develop.
