DNA can already tell us the sex and ancestry of unknown individuals, but now an international team of researchers is beginning to connect genetics with facial features, degrees of femininity and racial admixture. They add that "by simultaneously modeling facial shape variation as a function of sex and genomic ancestry along with genetic markers in craniofacial candidate genes, the effects of sex and ancestry can be removed from the model thereby providing the ability to extract the effects of individual genes. In essence, by including sex and racial admixture, researchers can learn about how certain genes and their variations influence the shape of the face and its features.

Our results revealed that the relative contribution of metrics and skin tone depended on both perceiver race and face race. Additionally, across all perceiver groups, skin tone had a more consistent impact than metrics on racial prototypicality ratings of White faces, with the reverse for Korean faces. For Black faces, the relative impact varied with perceiver race: skin tone had a more consistent impact than metrics for Black and Korean perceivers, with the reverse for White perceivers.

The proliferation of minority populations in the US workforce has increased the need to investigate differences in facial dimensions among these workers. The objective of this study was to determine the face shape and size differences among race and age groups from the National Institute for Occupational Safety and Health survey of US civilian workers. Measurements of height, weight, neck circumference, and 18 facial dimensions were collected using traditional anthropometric techniques.

Selfies, headshots, mug shots — photos of oneself convey more these days than snapshots ever did back in the Kodak era. Most digitally minded people continually post and update pictures of themselves at professional, social media and dating sites such as LinkedIn, Facebook, Match. As such, it can be a stressful task to select the photo that conveys the best impression of ourselves.

Context: The facial proportion is essential for preoperative and postoperative assessment in reconstructive and aesthetic surgery. For many years, the neoclassical canon has commonly been used to define the facial morphology features. Aims: The purpose of this study was to assess the validity of neoclassical facial canons and explore its variants in Madagascar population.

However the more attractive a face is, regardless of ethnicity, the less the variations from the mask seem to occur. That is, in the attractive face from any ethnic group the correlation with the mask is extremely high. It is somewhat artificial to put people into categories, since even people placed in the same category can have significant variations.
