Gilbert Gottlieb was an elegant experimentalist whose research was inspired in part by naturalistic observations of parent-offspring vocal-auditory interactions of waterfowl. Such observations are essential in identifying potential linear (obvious) as well as nonlinear (subtle) mechanisms underlying the development of species-typical behavior. His…

In mammalian species, behavior begins in utero, hidden within the mother's body. This biological fact has made it difficult to observe or to access fetuses, leaving the beginnings of behavior to the imagination or allowing it to be forgotten or ignored. Such truncation of perspective probably helped many to consider behavioral capabilities first…

Discussed are the ontogenetic and evolutionary implications of Dr. Gottlieb's perinatal research with ducklings. His evolutionary theory which proposes that behavior is the primary engine driving evolution is reviewed as is his experimental examination of behavioral neophenotypes. The methodology and findings from Gottlieb (1991/2007) are…

Gottlieb used naturalistic observations of normally occurring events in the life history of individuals for the purpose of discovering the role of experience in the development of species-typical behaviors. His research revealed the impact of self-generated experiences (particularly those experiences that were self-stimulated) in the establishment…

Gilbert Gottlieb's formative role in establishing a science of experimental behavioral embryology is described. His experimental program on the development of species identification served as a model for developmental psychobiologists seeking alternatives to the nature-nurture dichotomies prevalent in the 20th century. Two of the major concepts…

Evolutionary developmental psychology is a discipline that has the potential to integrate conceptual approaches to the study of behavioral development derived from psychology and biology as well as empirical data from humans and animals. Comparative research with animals, and especially with nonhuman primates, can provide evidence of adaptation in…
