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…

Gilbert Gottlieb's 1991/2007 paper provides a fine example of his creative, experimental approach to behavioral embryology. As this paper shows, he gave the field insight into the role of development in evolution, backed with strong empirical evidence.

In addition to his pioneering studies on prenatal development of social responses in the mallard, Gilbert Gottlieb made important theoretical contributions to the study of the evolution of behavior. This tribute to Gottlieb presents his early view that prenatal behavioral development is the product of evolution and his revision of this view in his…

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…

In the wake of his death, it is a fair tribute to Gilbert Gottlieb to recognize him as a central figure in the creation of conditions that permitted the introduction of developmental thinking in developmental psychology. These included exposing the sterility of the nature-nurture debate and the adoption of a biological framework that conceives of…

Gilbert Gottlieb's data and epigenetic approach support the conclusion that organisms are functionally-whole agents at each phase of development rather than simply incompletely developed adults prior to sexual maturity and deteriorated adults in old age. This implies that organisms construct distinct ontogenetic niches at each phase of…

Gottlieb's (1991/2007) target article represents a milestone in our understanding of the impact of social experience on developmental malleability. Interactions across the species-typical and operant behavior categories are increasingly understood to exist. The social contingencies present in the normal species-typical developmental manifold are…

To test the hypothesis that social rearing may induce malleability, socially reared and socially isolated mallard duck, Anas platyrhynchos, embryos and hatchlings were exposed to the maternal call of a chicken, Gallus gallus domesticus, until 48 h after hatching. The hatchlings were then tested with the chicken call versus the mallard maternal…

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…
