The conclusions drawn by researchers in a study conducted at the University of Utah include that male human cranial structure, particularly that of the jaw, has evolved to minimize damage during physical altercations.
Researchers studied the bone structure of australopiths, ape-like bipeds living four to five million years ago. They discovered that australopith jaws were strongest in areas most likely to receive injury in fist fights. The researchers believe that this facial structure has remained similar to present day and explains current “robust” features of males
