Selection in species with aggressive social interactions favours the evolution of cognitive mechanisms for assessing physical formidability (fighting ability or resource-holding potential). The ability to accurately assess formidability in conspecifics has been documented in a number of non-human species, but has not been demonstrated in humans. Here, we report tests supporting the hypothesis that the human cognitive architecture includes mechanisms that assess fighting ability—mechanisms that…

The Importance of Physical Strength to Human Males
TLDR
Data are reviewed showing that better fighters feel entitled to better outcomes, set lower thresholds for anger/aggression, have self-favoring political attitudes, and believe more in the utility of warfare.
Muscularity and Strength Affect Individual Variation in Self-Perception of Fighting Ability in Men
TLDR
The more muscular men perceive their fighting ability as being greater, and not only because they are stronger (at least in the HGS task), it seems that men take into account the overestimation the robustness of the relationship between strength and muscularity that prevails within his peers.
Cues of upper body strength account for most of the variance in men's bodily attractiveness
TLDR
Contrary to popular theories of men's physical attractiveness, there was no evidence of a nonlinear effect; the strongest men were the most attractive in all samples.
Human's Cognitive Ability to Assess Facial Cues from Photographs: A Study of Sexual Selection in the Bolivian Amazon
TLDR
The results support the existence of a human ability to identify objective traits from facial cues, as suggested by evolutionary theory.
Face of a fighter: Bizygomatic width as a cue of formidability.
TLDR
The hypothesis that bizygomatic width is a cue of formidability that is assessed during agonistic encounters is supported.
Perceived Aggressiveness Predicts Fighting Performance in Mixed-Martial-Arts Fighters
TLDR
The results indicate that perception of aggressiveness and fighting ability might cue different aspects of success in male-male physical confrontation.
Female Perceptions of Male Body Movements
TLDR
Evidence is presented for the assertion that male dance movements in particular affect female mate preferences, and some ideas for future research directions to stimulate the scientific investigation on the significance of male body movements in the context of inter- and intrasexual selection are presented.

Testosterone increases perceived dominance but not attractiveness in human males
TLDR
The authors' data indicate that high testosterone faces reveal dominance, and there is no evidence of directional selection for increased (or decreased) testosterone in terms of attractiveness to the opposite sex, contrary to predictions.
Evolutionary Psychology of Facial Attractiveness
The human face communicates an impressive number of visual signals. Although adults' ratings of facial attractiveness are consistent across studies, even cross-culturally, there has been considerable
Why Is Muscularity Sexy? Tests of the Fitness Indicator Hypothesis
TLDR
Men with moderate muscularity are rated most attractive, and women rate muscular men as sexier, more physically dominant and volatile, and less committed to their mates than nonmuscular men.

Effects of sexual dimorphism on facial attractiveness
TLDR
The results of asking subjects to choose the most attractive faces from continua that enhanced or diminished differences between the average shape of female and male faces indicate a selection pressure that limits sexual dimorphism and encourages neoteny in humans.

Staying alive: Evolution, culture, and women's intrasexual aggression
TLDR
Cultural interpretations have "enhanced" evolutionarily based sex differences by a process of imposition which stigmatises the expression of aggression by females and causes women to offer exculpatory (rather than justificatory) accounts of their own aggression.
