presentations. Several pieces of indirect evidence suggest biocultural interpretations for encephalization (Beals 1987). First, expansion of the brain case has been greater than is explicable by the corresponding increase in body size. Second, average human relative endocranial volume (24.9 cm3 per kg of body weight) is more than twice that of apes. "Biophysical" variables like body surface area, thermoregulation, and cranial geometry fail to fully explain the changes observed for hominid data…

TLDR
Evidence supports the hypothesis of cold adaptation among "Classic" Neandertals and it is probable that a decrease of the cranial index occurs from the Middle to Upper Paleolithic, and during the Holocene, the index increases under all climatic conditions.
