Impact of sampling strategies and reconstruction protocols in nasal airflow simulations in fossil hominins
International audience In their study, de Azevedo et al. (1) employ a sample of 12 individuals from Argentina of Chinese, Japanese, and Korean origin [northeastern Asians (NEA)] as representative of cold-adapted populations. However, all previous literature on the subject shows that the craniofacial...
