Several studies have shown the importance of confidence and even overconfidence in participating in warfare. Some researchers have proposed that religion is an evolutionary adaption for the capacity to participate in warfare, in part due to its abilit . . .

Throughout vertebrate evolution, asymmetries in the ability to inflict costs and defend resources (i.e., formidability) likely impacted individual fitness and collecting information about formidability (e.g., size, strength, fighting ability) would ha . . .

The human female orgasm, has often been a topic of debate in evolutionary scholarship. Some scholars argue that it evolved to aid in sperm selection of high quality males, others argue that it evolved as part of a pair-bond maintenance system, and som . . .

Determining the reasons behind how and why evolutionary mechanisms that establish or remove genetic variations within a population is a fundamental question in evolutionary biology. by tying together, the origin, evolutionary patterns, molecular mecha . . .

Previous research has documented that human females report a number of preference changes for sexual partners and sexual activity during the high- relative to low-fertility days of the ovulatory cycle. Less studied, however, are the effects of female . . .

Humans assess formidability though a variety of cues including weaponry, group size, and incapacitation (Fessler, Holbrook, Snyder, 2012; Fessler & Holbrook, 2013a, Fessler & Holbrook, 2013b). These studies argue that formidability is heuristically re . . .
