The stone artefacts made by modern humans at Liang Bua show some continuity (particularly in knapping techniques) with those produced by Homo floresiensis. However, there are also some marked differences. The proportion of artefacts manufactured from fine-grain chert increases dramatically with the arrival of modern humans, and many of these chert flakes exhibit edge-gloss that were probably caused by cutting soft materials like grass. In addition, many more artefacts show signs of burning, although these may have been due to accidental exposure to fire, rather than intentional heating. These differences indicate that the modern humans and Homo floresiensis exhibited different behaviours in the ways that they used stone tools and other technological means, such as fire use by modern humans, to extract and process resources.
What techniques did Homo floresiensis use to create stone tools and what does this tell us about its behaviour and environment?
