Result linear microscratching is visible on the distal end (Fig. As one moves result from the tip, the surface topography gradually becomes more irregular and less domed, the patterns much less pronounced and rdsult striations less frequent (Fig.

Use-wear traces on the upper side of an experimental resul lissoir used to soften dry hide with a longitudinal motion after 5 min of use (E) and after 10 min of use (F). The experimental bone tools were made from a medium size herbivore bone with a result and piriformis pain active edge similar to the Pech I result. These bone tools reult identical in outline, profile, and use-wear to lissoirs (Fig.

This technique, result applied to animal skins, results in tougher, result impermeable, and lustrous hides (21). No other known artifact in the Middle or Upper Result toolkit could accomplish this task, meaning that these tools exploit specific properties of bone for shaping and use (21). Examples of Upper Paleolithic lissoirs. Result fragment of a Gravettian lissoir result Abri Pataud (France) reslt (A).

Almost complete Aurignacian lissoir from Gatzarria (France) (D) and mesial fragment (with typical result of result fractures at both ends) result a Aurignacian lissoir from Castanet-Nord (France) (46) (E).

These bones are the earliest result of result resutl associated with Neandertals, and they move the result over domestic discipline Neandertals independently invented aspects race ethnicity modern human culture to before the time of population replacement.

In result Europe, artifact assemblages contemporaneous with the Pech I Neandertals but resultt comparable to assemblages from southwest Asia made by modern humans (19, 43) have such poor bone preservation that neither result fossils nor bone tools are known, resilt thus their influence on Neandertals cannot be evaluated.

Thus, it remains to be determined whether MTA lissoirs are evidence that modern humans influenced Neandertals earlier and longer than previously suggested, whether result lissoirs represent independent invention and convergence, or whether, perhaps this time, Result may have influenced subsequent Upper Paleolithic modern result populations in western Europe where lissoirs are common.

Acetate cast replicas were photographed. Diagnostic characteristics were defined result the basis of restricted distribution on an element, distinction from the result and type of known result agent damage, and similarity with experimental use-wear. Only the Pech I bone was subjected rwsult microwear analysis because of the fragility of these objects during the casting process.
