Understanding Palaeolithic adaptations through niche modelling - the case of the French Middle Gravettian

“The French Middle Gravettian represents an ideal case study for attempting to identify mechanisms behind the diversity observed in the archaeological record.” Why is the authors advocate so? Do the authors mean by “diversity” the lithic techno-typological variability? Is the lithic variability the main characteristic that makes this a perfect case study? Introduction. “These two typo-technological facies appear to differ both chronologically and geographically.” According to the state-of-the art presented by the authors, this seems not to be the case. Both industries are overlapping chronologically and geographically. In fact, this is one of the aspects considered later in the results and discussion section. As an example, the poor absolute chronological dating of some of the sites is problematic, as discussed by the authors, and pointed as one of the main limitations of the study.
