Biophilia is Edward O. Wilson's most personal book, an evocation of his own response to nature and an eloquent statement of the conservation ethic. Wilson argues that our natural affinity for life―biophilia―is the very essence of our humanity and binds us to all other living species.

Infantile physical morphology—marked by its “cuteness”—is thought to be a potent elicitor of caregiving, yet little is known about how cuteness may shape immediate behavior. To examine the function of cuteness and its role in caregiving, the authors tested whether perceiving cuteness can enhance behavioral carefulness, which would facilitate caring for a small, delicate child. In 2 experiments, viewing very cute images (puppies and kittens)—as opposed to slightly cute images (dogs and cats)—led to superior performance on a subsequent fine-motor dexterity (...) task (the children’s game “Operation”). This suggests that the human sensitivity to those possessing cute features may be an adaptation that facilitates caring.. (shrink)

Trivers’s theory of parental investment suggests that adults should decide whether or not to invest in a given infant using a cost-benefit analysis. To make the best investment decision, adults should seek as much relevant information as possible. Infant facial cues may serve to provide information and evoke feelings of parental care in adults. Four specific infant facial cues were investigated: resemblance (as a proxy for kinship), health, happiness, and cuteness. It was predicted that these cues would influence feelings of (...) parental care for both sexes, but that resemblance would be more important for men than women because of the importance of paternity uncertainty in the ancestral environment. Seventy-six men and 76 women participated in a hypothetical adoption task in which they made judgments of infant faces. Average zero-order, partial, and component score correlations all revealed that men placed primary emphasis on cues of resemblance, while women placed primary emphasis on cues of health and cuteness (cues of infant quality). The correlations also showed that men placed a significantly greater emphasis on cues of resemblance than did women. (shrink)
