Abstract Breasts of human females are large compared to those of closely related primate species, and they can thus be hypothesized recently or currently to have been subject to directional sexual selection. [...] Key Result These conclusions were similar in studies from two cultures differing in fecundity and breastfeeding traditions (Spain; New Mexico, U.S.A.). Choosy males that prefer females with symmetrical breasts may experience a direct fitness benefit in terms of increased fecundity and an indirect…Expand

Breast asymmetry and phenotypic quality in women
TLDR
The data support the thesis that mammotropic hormones, particularly estrogen, are harmful because they suppress the immune system and support the hypothesis that large and symmetric breasts are honest signals of high phenotypic quality in women. Expand
Stereotypical and Actual Associations of Breast Size with Mating-Relevant Traits
TLDR
Women and men perceived breasts in a similar way to each other: the bigger the breasts the higher the reproductive efficiency, lactational efficiency, sexual desire, and promiscuity attributed to the woman, but large breasts were not regarded more attractive than average ones, though small breasts were the least attractive. Expand
Men’s preferences for women’s breast size and shape in four cultures
TLDR
A survey on men's preferences for breast morphology in four different cultures found systematic directional preferences for firm breasts, which supports the idea that breast morphology may serve as a residual fertility indicator, but offers more limited support for the potential fertility indicator hypothesis. Expand
Breast size and asymmetry during pregnancy in dependence of a fetus's sex
TLDR
Women with bigger, symmetrical breasts, with a greater increase in size during pregnancy, should be more likely to carry a more ecologically sensitive and energetically demanding male fetus. Expand
Evidence for Genetic Variation in Human Mate Preferences for Sexually Dimorphic Physical Traits
TLDR
In a large sample of twins, forced-choice, dichotomous mate preferences for height, skin colour, hair colour and length, chest hair, facial hair, and breast size are assessed. Expand
Asymmetry and the menstrual cycle in women
TLDR
Evidence is presented from studies of non-sexually selected traits and a sexually selected trait that, in characters made up wholly or in part of soft tissue, CA varies across the menstrual cycle in women, which could mean that temporal changes in CA could be used by males to indicate a female's position in the cycle. Expand
Female sexual advertisement reflects resource availability in twentieth-century UK society
TLDR
The results indicate that female sexual display increases as economic conditions decline, with the level of breast display and the tightness of clothing at the waist and hips the key factors underlying this increase. Expand
Breast symmetry, but not size or volume, predicts salivary immunoglobulin-A (sIgA) in women
TLDR
Results support the hypothesis that symmetrical female breasts are a cue to underlying immunocompetence, as well as controlling for Body Mass Index, breast size, and volume. Expand
Female health, attractiveness, and desirability for relationships: Role of breast asymmetry and waist-to-hip ratio
Abstract Fluctuating asymmetry (FA) of ordinarily bilaterally symmetrical traits in humans has been proposed to indicate developmental anomaly. Recent research has shown that individuals with minimalExpand
Beauty and Sex Appeal: Sexual Selection of Aesthetic Preferences
When female barn swallows search for a prospective father of their future offspring, they are far from accepting every male they meet. Instead, they strongly prefer males with long and symmetricalExpand

Human female orgasm and mate fluctuating asymmetry
TLDR
The proportion of a woman's copulations associated with orgasm is predicted to be associated with her partner's fluctuating asymmetry, and a questionnaire study of 86 sexually active heterosexual couples supported this prediction. Expand
Hypothesis for the Evolution of Human Breasts and Buttocks

TLDR
It is proposed that breasts and buttocks evolved to signal the female's nutritional state to males, in the context of facilitating female choice of mate, and that humans stand out against a general background of sexual selection wherein many animals exhibit male ornaments to attract females. Expand

Female swallow preference for symmetrical male sexual ornaments
TLDR
Male swallows with elongated, symmetric tails mated earlier, and enjoyed larger annual reproductive success than did males with shortened tails and increased asymmetry, which suggests that females in their mate choice use ornament asymmetry and size as reliable indicators of male quality. Expand
Human (Homo sapiens) facial attractiveness and sexual selection: the role of symmetry and averageness.
TLDR
This is the first study to show that facial symmetry has a positive influence on facial attractiveness ratings, with the exception of the hypothesized effects of averageness of female and male faces on attractiveness ratings. Expand

Fluctuating asymmetry as a possible measure of developmental homeostasis in humans: a review.
TLDR
Experimental data and the literature support the first hypothesis and indicate that individuals who suffer from chromosomal or polygenic morbidity and from anomalies or conditions of development with still unknown genetic components demonstrate an elevated FA of various structures. Expand
Parasites differentially increase the degree of fluctuating asymmetry in secondary sexual characters
TLDR
It is suggested that the degree of fluctuating asymmetry in tail ornaments, but not in other feather traits, reliably reveals the level of parasite infestation, which has important implications for the ability of conspecifics to use the size and the expression of ornament in assessment of phenotypic quality and thus in sexual selection.
