Proposes a molecular mechanism for the coupling of phosphorylation to electron transport in both mitochondria and chloroplasts. Justifies the proposed reaction schemes in terms of thermodynamics and biochemical data. Suggests how areobic respiration could have evolved. (EB)

The unique power of Jacob Bronowski's humanism comes from his commitment to the individual. Yet the individual can only flourish in a democratic society which allows people to cultivate their potential, something which must be done within the context of responsibility to humanity. (IS)

Discusses the role of play in development from both cultural-evolutionary and ontogenetic-historical perspectives. These perspectives illuminate how play and imitation are important for the developing individual who is seen as influencing a changing cultural environment. (Author/RH)

Presents an interview with Pat Shipman, author of the 1994 book "Evolution of Racism." (YDS)

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)

Presents an activity on natural selection and how the peppered moth's adaptive values for their colors changed during the Industrial Revolution in Manchester, England, influencing their survival and ultimately affecting the survival of their offspring. Includes activity objectives. (Author/KHR)

Describes how burying beetles can be used to explore conflicts between breeding individuals. Discusses conflict over the ownership of the resource and of the breeding group. (JRH)

Discusses recent evolution education literature and highlights key themes and perspectives recognized in the scientific community but only minimally exposed within either the science classroom or the science education research agenda. Discusses recommendations to address these important omissions within the science educator community. Contains 61…

Recounts a debate between Theodore Roosevelt and Abbott Thayer in 1909-12 over whether animal coloration was an adaptation resulting from natural selection or whether the animal's environment acted directly on it to form its color patterns. (ZWH)

A discipline in which scientists seek to simulate and synthesize lifelike behaviors within computers, chemical mixtures, and other media is discussed. A computer program with self-replicating digital "organisms" that evolve as they compete for computer time and memory is described. (KR)

Examines the role mistakes play in the molecular evolution of bacteria. Discusses the interacting physical, chemical, and biological factors that cause changes in DNA and play a role in prokaryotic evolution. (DDR)
