Proposes models for the evolution of the genetic code and translation mechanisms. Suggests that the translation process is so complex and precise that it must have evolved in many stages, and that the evolution of the code was influenced by the constraints imposed by the evolving translation mechanism. (EB)

Traces the growth of theories of eugenics during the twentieth century, focussing on the work of H. J. Muller. Concludes that "Muller's lasting contribution was to write the hereditarian attitudes associated with traditional eugenics and the environmentalist's viewpoint associated with modern sociology to obtain a humane and reasoned approach to…

Discusses major leaps in knowledge about the production of flowers that have come from studying genes that regulate the flowers of mouse ear cress (Arabidopsis thaliana). Examines the ABC model of flower morphogenesis, commonality of genes, evolution of angiosperms, and agricultural and horticultural potential. (LZ)

Describes a classroom activity that teaches the mechanism of genetic drift to undergraduates. Illustrates a number of concepts that are critical in developing evolution literacy by sampling M&M milk chocolate candies. (MM)

Gives an overview of human history, relating cultural changes with resulting changes in population density and in ecological balance to patterns of infectious diseases in man. Discusses mechanisms of evolution of resistance. Suggests that in populations where infectious diseases can be controlled, attention should shift to degenerative diseases…

Analyzes 50 major textbooks in the fields of evolution, biology, ecology, genetics, paleontology, and systematics, focusing on how the conceptual framework of evolution as a process is presented and developed in those fields. Lists definitions of evolution provided in the textbooks and discusses the implications of the findings. Contains 56…

Discusses the interaction of biological knowledge and human values, emphasizing problems raised by man's ability to control human evolution. Analyzes moral and religious concerns about eugenic artificial insemination or nuclear transplantation, including implications for the structure of the family and the basis of parenthood. (EB)

Discusses opportunities and challenges for the field of evolutionary biology, particularly in areas related to molecular genetic technologies, the environment, biodiversity, and public education. (Author/KHR)
