attraction in bower birds and humans It is widespread in nature that first attraction is based on external factors such as looks, bowers or yachts. But as experience grows, matters of character tend to displace superficialities. As bower birds accumulate a year or two’s experience, the females’ attention turns from well-arranged baubles (easily stolen from a rival) to energetic displays/dances that are not so readily faked. In humans, hip-to-waist ratio and symmetry, seen for instance in photographs, determine whether a potential partner is regarded as desirable. After sharing a work environment with potential partners seen in the photographs, participants are asked to rate their colleagues in order of attractiveness. The order of such a rating changes from first impressions as character traits are noted, traits such as co-operativeness.
