The story of biology is far more complex and fascinating than straightforward facts or neatly labeled diagrams of structures and systems. Although exams can motivate students, the key to using these extrinsic motivators to increase student understanding lies in the way the assessments are designed and what they measure. Those involved in…

Describes a sectoral and paradigmatic approach to evolutionary research. Argues that an evolutionary paradigm does not exist. Examines the socio-biological approach and that of a system-theoretical oriented general evolutionary theory. Utilizes the topics of cooperation, delimitation, and indoctrination to explain more promising ways of adoption.…

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)

Comments on the personalities and viewpoints of Richard Leakey and Donald Johanson, paleoanthropologists who hold differing views on the origin of humans. Summarizes major paleoanthropological finds and suggests the use of radio-immunoassay techniques for untangling the human family tree. (JN)

Describes chronologically the evolution of the human race on earth so as to refute Darwin's theory of descent from animals. Skull fragments from sites around the world suggest at least two possible routes toward the emergence of Homo sapiens sapiens. (Author/SK)

The struggle for academic freedom in nineteenth century Ontario was closely bound to the acceptance of evolutionary theory. A history is given of the impact of Darwin's theories on the evolution of academic freedom in Canadian universities. (CJB)

In artificial life research, scientists use the principles of evolution to develop complex behaviors from simple elements. By creating lifelike processes, they are trying to understand real organisms and explore possibilities for life in other circumstances. Techniques used are diverse, including biological testing, robotics, and computer…

Examines evolutionary trends, specifically trends in size, complexity, and fitness. Notes that documentation of these trends consists of either long lists of cases, or descriptions of a small number of salient cases. Proposes the use of random samples to avoid this "saliency bias." (SR)

Highlights major activities, conferences, conference and published papers, monographs, and research studies in paleobotany during 1982. Indicates that paleobotanists made more frequent use of the perspectives and ideas of disciplines as developmental biology and sedimentology in their research endeavors. (Author/JN)

Describes recent research by Edward Steele appearing to support the Lamarckian theory of inheritance. Steele suggests that a mutant somatic cell favored by the environment will undergo clonal expansion. Altered genetic materials from these cells is then picked up by C-type viruses and inserted into the germ line genome. (CS)

This study discusses the behavior of the females of the parasitic wasp Nasonia vitripennis, which adjust the sex ratio of their broods according to whether or not they are the first or second wasp to parasitize a host. The results provide a quantitative test of sex ratio theory. (Author/SA)

Reviews creationist arguments attacking scientific evidence for evolution and an old earth, presenting counter-arguments from the evolutionist's point of view. (CS)

The author reviews research on the origins of life, beginning with Thales (636 B.C.), synthesized by C. Darwin in "The Origin of Species," continued by H. DeVries' mutation theory, and enhanced by the discovery in 1944 of DNA. For journal availability, see SO 505 260. (AV)

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)

Examines three types of gaps in the fossil record: real gaps, imaginary gaps, and temporary gaps. Reviews some recent evidence concerning evolution from the paleontological record of microfossils, invertebrates, and vertebrates in order to make some general conclusions regarding the manner in which life evolved on earth.
