A complete understanding of life involves how organisms are able to function in their environment and how they arise. Understanding how organisms arise involves both their evolution and development. Thus to completely comprehend living things, biology must study their function, development and evolution. Previous proposals for standardized…

New science standards and reform recommendations spanning grades K--16 focus on a limited set of key scientific concepts from each discipline that all students should know. They also emphasize the integration of these concepts with science practices so that students learn not only the "what" of science but also the "how" and…

Explores the evidence and reasoning behind the claims of biologists that variations in the genetic code are compatible with the claim of common ancestry. (Author/KHR)

Designates four challenges for a theory of evolutionary pedagogics which result from the theoretical progress made in biological science: (1) subjectively perceived autonomy; (2) teachability; (3) preparation for future life; and (4) the reality norm dilemma. Argues that these confrontations are the theoretical challenges for the further…

A historically rich teaching intervention was developed for biological evolution with the intent of promoting a conceptual change from students' initial understanding to a more Darwinian understanding. Results from evaluation of the intervention indicate promise in the use of historical materials in conjunction with a conceptual change strategy.…

Reports on a meeting in China in 1999 that focused on the origins of animal body plans and their fossil records. Discusses the theoretical implications of fossils that preserve internal as well as external structures. (DDR)

Summarizes the views of Ernst Mayr on the controversy over evolution which exists between physical scientists and biologists. Discusses the uniqueness of individuals, work by population geneticists and mathematical geneticists, complexity in nature, rates of change, modes of change, and the need to ask "why". (DC)

Interprets Edward Spranger's "Forms of Life" against the background of the findings of modern biology. Shows how far Spranger's diagnosis of different human types, which are not affected by external influences on characteristics, conform with research hypotheses of modern biological sciences. (CAJ)

The concept of paraphyly is defined and its importance in the teaching of evolution and taxonomy is discussed. Examples are included to illustrate this concept. A list of 14 references is provided. (CW)

The carpel is a highly modified leaf enclosing the ovules. This article describes methods for teaching about the evolution of the carpel and the nature of carpel fusion. Presents an illustration of the evolution of the most common types of compound pistil arrangement from the ancestral single-carpel marginal type of placentation. (PR)

Cites the public image problem of field biologists and systematists. Discusses systematics and natural history including species variation, ecology, management of organisms and appreciation of nature. Describes widespread fallacies which downplay the importance of field biology and suggests ways to improve its image. (CW)

Discusses a theoretical model that uses a game as a base for studying processes of a stochastic nature, which involve chemical reactions, molecular systems, biological processes, cells, or people in a population. (MLH)

Discusses some principles of biological taxonomy. The evolutionary principle in taxonomy and its limitations, and the difference in evolutionary patterns between plants and animals, are also discussed. (HM)

This laboratory exercise integrates the topics of cell structure, classification of living organisms, and evolution. It is suitable for secondary or college biology courses and was used in an interdisciplinary science course for nonscience majors. (BB)

Presents experiments using wild birds as predators and pastry as prey and colored stones as background to demonstrate natural selection. Describes the exercise as an exercise in simulating natural selection. (Author/CW)
