Smile Reproducibility and Its Relationship to Self-Perceived Smile Attractiveness. D Dobreva, N Gkantidis, D Halazonetis, C Verna, G Kanavakis.

Our results show that lip morphology during smiling is highly consistent among young adults. Females presented higher consistency in the shape of the smile, including lip morphology, compared to males. Self-perceived smile attractiveness was not associated to smile consistency.

Genetic variants underlying differences in facial morphology in East Asian and European populations. M Zhang, S Wu, S Du, et al.

Evolutionary analyses suggest that the difference in nose shape between EUR and EAS populations is caused by a directional selection, due mainly to a local adaptation in Europeans. Our results illustrate the underlying genetic basis for facial differences across populations.
