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…

Taking into account the historic transitions and progressions in agricultural science, this article examines the emergence of the phenomenon of agricultural biotechnology. It identifies pivotal sites of tension between agricultural biotechnology and alternative approaches to agriculture. The article identifies two distinct sources of contemporary…

Outreach efforts by faculty members are oftentimes limited in scope due to hectic schedules. We developed a program to enhance science literacy in elementary school children that allows experts to reach a tremendous audience while minimizing their time commitment. The foundation of the program is a television series entitled "Desert Survivors."…

This paper focuses on a learning strategy designed to overcome students' difficulty in understanding evolutionary change within the framework of geological time. Incorporated into the learning program "From Dinosaurs to Darwin: Evolution from the Perspective of Time," this strategy consists of four scaffolded investigations in which…

Several implications for the understanding of the Darwinian revolution follow from an analysis of the role of colloquial language and prudential reason in Charles Darwin's quest for a theory of evolution. First, the term "natural selection" is not merely or even primarily a technical term and thus cannot be understood accurately apart…

Conclusion of a three-part article in which the author discusses the implications for zoology and paleontology today and summarizes with comments on the "model" aspects of the controversy and its resolution. (BR)

Part II of a three-part article describes the growth of scientific understanding of the reptile-mammal transition and its place in evolution. (BR)

A proper understanding of the role of culture in development can make a significant contribution to the development of theory and offer a more certain guide to practice than current theories afford. Three frameworks for interpreting the influence of nature and nurture on individual development assign biological and environmental factors a direct…

Provided in this document are reviews of 31 creationist publications. The reviews, written by Iowa teachers and scientists, were conceived in 1982 during a drive by Iowa creationists to install their books and other materials in the schools of 60 Iowa communities. Introductory comments on the format of the reviews and several generalizations are…

The first of a three-part article in which the author discusses some past events which provide insight into why the theory of evolution gradually displaced the doctrine of special creation. (PEB)

Describes some uses of pocket-size electronic calculators in biology classes; for example, charting exponential population curves, evolution by natural selection, and random genetic drift. (PEB)

Discusses the implications of proposed legislation which would prohibit the teaching of either the theory of evolution or creationism unless both are taught and relates this area of controversy to the relationship of science and politics, to the question of what is to be accepted as appropriate curriculum, and to attempts to instill fundamentalist…
