In the mid-20th century, French archaeologist François Bordes debated against American archaeologist Lewis Binford to explain this diversity (the "Bordes–Binford debate"), with Bordes arguing that these represent unique ethnic traditions and Binford that they were a response to varying environments (essentially, form vs. function). The latter sentiment would indicate a lower degree of inventiveness compared to Cro-Magnons, adapting the same tools to different environments rather than creating new technologies. A continuous sequence of occupation is well documented in Grotte du Renne, France, where the lithic tradition can be divided into the Levallois–Charentian, Discoid–Denticulate (43,300 ±929 – 40,900 ±719 years ago), Levallois Mousterian (40,200 ±1,500 – 38,400 ±1,300 years ago), and Châtelperronian (40,930 ±393 – 33,670 ±450 years ago).
