Suggests a resolution to the apparent conflict between the Freudian and humanistic/transpersonal views of human nature. Presents a model which allows for the fulfillment of Freud's desire to account for both the life and death instincts as manifestations of a tendency to restore an earlier state of things. (LLL)

Discusses the divergence of apes from the Old World monkeys and the later divergence of humans from apes. Contrasts current views with those held approximately five years ago. Topics considered include hominoid evolution, hominoid radiation, dryomorphs and ramamorphs, appearance of the first hominids, and adaptive radiation of these hominids. (JN)

Argues that creationism endures in spite of, and because of, the scientific community's response. Analyzes the creationism controversy between 1975 and 1990. Finds scientists unresponsive to the public appeal of creationism which is grounded in empiricist folk epistemology. Discusses implications for the relationship between technical and public…

Constructs an evolutionary sequence to account for the diversity of ion pumps found today. Explanations include primary ion pumps in bacteria, features and distribution of ATP-driven pumps, preference for cation transport, and proton pump reversal. The integrated evolutionary hypothesis should encourage new experimental approaches. (DH)

Discusses various bioethical issues and problems related to animal welfare and animal rights. Areas examined include: Aristotelian views; animal welfare legislation; Darwin and evolutionary theory; animal and human behavior; and vegetarianism. A 14-point universal declaration of the rights of animals is included. (JN)

This document points out that creationists claim that humans and dinosaurs lived together in Texas just before Noah's flood by citing alleged human footprints found side-by-side with those of dinosaurs in the Cretaceous limestone of the Paluxy River near Glen Rose, Texas. An investigation was conducted to determine if this claim were true.…

Recent developments in molecular biology and new interpretations of the fossil record are gradually altering and adding to Charles Darwin's theory, which has been the standard view of the process of evolution for 40 years. Several of these developments and interpretations are identified and discussed. (JN)

Discusses how existential philosophy and evolutionary biology enjoy substantial and hitherto unappreciated similarities, in particular in understanding life's fundamental absurdity, a relentless and productive focus on the individual, and an optimistic presumption of freedom. (SAH)

Outlines principles of evolutionary theory, including such recent changes as punctuated equilibria. Indicates that the incompleteness of Darwin's theory has been replaced with a conceptual framework and empirical information. Controversial issues remain, but the basic ideas still stand strong. (DH)

A three-dimensional theory of frustration-aggression is presented. It is proposed that aggressiveness can be measured by computing the kinetic energy of a response. Aggressiveness is equated with energy state. Experimental and laboratory procedures are outlined. (Author/BEF)

Demonstrates the use of geological concepts and principles as an effective approach to teaching evolution and in turn the nature of science and the scientific method in the classroom. This approach to teaching makes it easier for students to understand the basic concepts of evolution which is really important in order to understand nature as it…

Discusses the work of evolutionary biologists in determining how sexual reproduction arose. Topics explored include the nature of sex, bacterial sex, meiotic sex, and asexual reproduction. A diagram (which can be used as a duplicating master) illustrating types of bacterial sex is included. (DH)

Reviews the history of the establishment of the concept of race. Traces the origins to the work of 17th- and 18th-century writers. Concludes that the notion of race became popular because it was associated with national identity and emerging ideas regarding evolution. (JDH)

Discovery that mutations accumulate at steady rates over time in the genes of all lineages of plants and animals has led to new insights into evolution at the molecular and organismal levels. Discusses molecular evolution, examining deoxyribonuclei acid (DNA) sequences, morphological distances, and codon rate of change. (DH)

Unlike animals, which heal, trees compartmentalize by setting boundaries that resist the spread of invading microorganisms. Discusses the creation of new walls by anatomical and chemical means in response to death of a branch or pruning. Points out that genetic control of compartmentalization has resulted from evolution of resistant species. (DH)
