First, I dont get the evolutionary and selection advantage of a strong/prominent square jaw. Can anyone explain that. Doesn't the length of the jawline matter far more? Some people don't have a prominent jaw from the front but when observed from the side the jaw is rather long and big. I know that defined chickbones indicate fighting capability of the individual and the fact that this individual can take more punches, thus the evolutionary advantage and preference of women for defined, pronounced chickbones. I understand that high fhwr and short face matters because men with such faces seem more strong, intimidating but strong jawline? How does the jaw intimidate other men, because I don't see any evolutionary advantage in it. And if it mattered wouldn't the length of the jaw be more important rather than its frontal square shape?
