Abstract From an evolutionary perspective, human facial attractiveness is proposed to signal mate quality. Using a novel approach to the study of the genetic basis of human preferences for facial features, we investigated whether attractiveness signals mate quality in terms of genetic diversity. Genetic diversity in general has been linked to fitness and reproductive success, and genetic diversity within the major histocompatibility complex (MHC) has been linked to immunocompetence and mate… Expand
The role of genetic diversity in human sexual selection : is the MHC special?
TLDR
The findings indicate that faces contain visual cues to mate quality in both males and females, providing support for evolutionary theories that the authors' preferences are adaptations for identifying mates of high quality. Expand
Genetic dissimilarity, genetic diversity, and mate preferences in humans
TLDR
Findings provide further support for a special role of the MHC in human sexual selection and suggest that male and female mate preferences may work together to potentially enhance both male andFemale reproductive success by increasing genetic diversity in offspring. Expand
Is genetic diversity associated with mating success in humans?
TLDR
Results provide partial support for a role of genetic diversity in human mating success, and females with greater MHC diversity were more successful at obtaining mates than less diverse females. Expand
MHC Class II Heterozygosity Associated With Attractiveness of Men and Women
TLDR
This study is the first to indicate a link between DQB1 and attractiveness in humans, and shows that the main gene related to facial attractiveness is the MHC class II DQB 1; a gene important also in viral infections and autoimmune diseases. Expand
Mixed-Ethnicity Face Shape and Attractiveness in Humans
TLDR
Results are consistent with evolutionary theories suggesting individuals should prefer heterozygosity in partners because facial cues to mixed-ethnicity are likely to indicate diverse genes compared to cues that indicate a face belongs to a single particular culture or population. Expand
MHC-correlated mate choice in humans: A review
TLDR
The idea that olfactory and visual channels may work in a complementary way to achieve an optimal level of genetic variability, methodological issues and interesting avenues for further research are discussed. Expand
Cross-Cultural Variation in Mate Preferences for Averageness, Symmetry, Body Size, and Masculinity
Sexual selection has greatly influenced the evolved biology, psychology, and culture of humans and favors individuals who choose healthy and fertile mates. Physical traits that cue quality areExpand
Does Genetic Diversity Predict Health in Humans?
TLDR
The current findings suggest that nonMHC diversity may play a role in both natural and sexual selection acting on human populations, and is found to predict male preferences for female faces. Expand
Genetic variation in the odorant receptors family 13 and the mhc loci influence mate selection in a multiple sclerosis dataset
TLDR
This study highlights complex patterns of genomic identity among partners in unrelated couples, consistent with a multi-faceted role for genetic factors in mate choice behavior in human populations. Expand
Geographic Variation in Chin Shape Challenges the Universal Facial Attractiveness Hypothesis
TLDR
Analysis of patterns of geographic variation in chin shape found significant geographic differences in male and female chin shape, consistent with region-specific sexual selection and/or random genetic drift, but not universal sexual selection. Expand

MHC-assortative facial preferences in humans
TLDR
A non-significant tendency for women to rate MHC-similar faces as more attractive, suggesting a preference for cues to a self-similar MHC in faces, consistent with other studies documenting assortative preferences in humans. Expand
Human facial beauty
TLDR
The hypothesis that both adults and children have a species-typical adaptation to the problem of identifying and favoring healthy individuals and avoiding parasite-susceptible individuals is proposed, and it is proposed that this adaptation guides human decisions about nepotism and reciprocity in relation to physical attractiveness. Expand
Good genes, complementary genes and human mate preferences
TLDR
As in animal studies, the authors are only just beginning to understand how preferences for specific traits vary and inter-relate, how consideration of good and compatible genes can lead to substantial variability in individual mate choice decisions and how preferences expressed in one sensory modality may reflect those in another.

Are human preferences for facial symmetry focused on signals of developmental instability
TLDR
The first detailed study of the patterns of asymmetry in human faces is provided, which suggests that people focus on aspects of facial asymmetry that may be revealing of developmental instability. Expand

TLDR
It is concluded that, although facial attractiveness is negatively related to developmental instability (as measured by asymmetry), attractiveness also signals different aspects of "quality" in the two sexes, independent of FA. Expand
MHC-associated mating strategies and the importance of overall genetic diversity in an obligate pair-living primate
TLDR
Evidence is found that mate choice is predicted in the first place by the ‘good-genes-as-heterozygosity hypothesis’ whereas the occurrence of extra-pair matings supports the “dissassortative mating hypothesis”. Expand
Common HLA Alleles Associated with Health, but Not with Facial Attractiveness
TLDR
Findings that support a new hypothesis relating HLA to health and a new method to quantify the level of heterozygosity are reported, which proposes that certain common HLA alleles confer resistance to prevalent pathogens. Expand
Does sexual dimorphism in human faces signal health?
TLDR
The results support the immunocompetence-handicap hypothesis for male faces in that masculine traits signalled health during adolescence, but suggest that any health-related evolutionary benefits obtained from preferences for attractive facial traits may be weak. Expand

TLDR
