Critiques

Several critiques have been placed against the traditional concept of behavioral modernity, both methodologically and philosophically. Anthropologist John Shea outlines a variety of problems with this concept, arguing instead for "behavioral variability", which, according to the author, better describes the archaeological record. The use of trait lists, according to Shea, runs the risk of taphonomic bias, where some sites may yield more artifacts than others despite similar populations; as well, trait lists can be ambiguous in how behaviors may be empirically recognized in the archaeological record. In particular, Shea cautions that population pressure, cultural change, or optimality models, like those in human behavioral ecology, might better predict changes in tool types or subsistence strategies than a change from "archaic" to "modern" behavior. Some researchers argue that a greater emphasis should be placed on identifying only those artifacts which are unquestionably, or purely, symbolic as a metric for modern human behavior.

Since 2018, recent dating methods utilized on various cave art sites in Spain and France have shown that Neanderthals performed symbolic artistic expression, consisting of red "lines, dots, and hand stencils" found in caves, prior to contact with anatomically modern humans. This is contrary to previous suggestions that Neanderthals lacked these capabilities.
