title: Evolutionary-derived anatomical characteristics and universal attractiveness.
abstract: Hominid fossils illustrate how modern humans have evolved anatomically. Included in the fossils are traits no longer phenotypically prevalent in humans (primitive) and phenotypic traits that have become increasingly prevalent (derived). In this study, published paleontological information about the anatomical evolution of humans was used to create line drawings of human form. Survey data were accumulated by having 759 individuals evaluate more than 40 anatomical traits. Each anatomical trait was presented as a panel of three line drawings intended to express the trait in a primitive, intermediate, and derived form. For each panel of three drawings, subjects were instructed to select the drawing they considered most attractive and then select the drawing they considered least attractive. The survey data indicate that males and females of diverse ages, races, cultures, and from varied geographical regions show commonality in their judgements of beauty of human form. The individuals surveyed appeared to have a strong aversion to primitive traits, preferring proportions and characteristics that are intermediate or more derived. In many instances, the evaluators preferred drawings that were exaggeratedly derived. The data may have relevance to the ongoing debate of whether averageness or atypicality is the essence of human beauty. Also, there was high agreement in judging the attractiveness of shapes and proportions in line drawings that were not immediately recognized to be representations of human form. These data could indicate that our general aesthetic sense for art, architecture, and fashion may be based on a subliminal reference to derived anatomical shapes and proportions. Overall, the data support the hypothesis that derived traits that are universally shared by anatomically modern humans may be the standard for our innate sense of beauty of human form.
