| Abstrakt: |
Behavioral development among the more complex vertebrates, the birds and the mammals, is a predictable and continuing change within a quasiclosed system. It entails the appearance, elaboration, and control of those behaviors that compose the interface between the two organisms, between the offspring and the parent and siblings, in the context of larger social and physical environment. The patterns of cuddling-cradling and cling-patting of primate infant-adult pairs, and of licking, huddling, and carrying of laboratory rodents and carnivores with their litters have a certain monotony that belies the complexity and the potential for plasticity of the behaviors which led to these end states. |
