Since the concept of a teddy bear is very obviously not a genetically inherited trait, we can be confident that we are looking at a cultural trait. However, it is a cultural trait that seems to be under the guidance of another, genuinely biological trait: the cues that attract us to babies (high foreheads and small faces). ① Cute, baby-like features are inherently appealing, producing a nurturing response in most humans. ② Teddy bears that had a more baby-like appearance ― however slight this may have been initially ― were thus more popular with customers. ③ Teddy bear manufacturers obviously noticed which bears were selling best and so made more of these and fewer of the less popular models, to maximize their profits. ④ As a result, using animal images for commercial purposes was faced with severe criticism from animal rights activists. ⑤ In this way, the selection pressure built up by the customers resulted in the evolution of a more baby-like bear by the manufacturers.
