The human external nose and its evolutionary role in the prevention of obstructive sleep apnea

We believe that the nose’s prominence has much to do with the so-called “cranial pincers” (i.e., the angulation between the anterior and posterior skull base, which developed during the phylogenetic development of Homo erectus). Cranial pincers form an angle—well known in anthropology as Huxley’s angle—that measures approximately 135 degrees in an adult male. None of the quadrupeds has this angle ; all of them have a straight skull base.
