Major differences between plants and animals are presented. Discussed are autotrophs and heterotrophs, plant growth and development, gas exchange, the evolution of plants, ecosystem components, the alleged inferiority of plants, and fungi. (CW)

Presented is a discussion of recent evidence on the evolution of human forms on earth gathered and evaluated using mitochondrial DNA techniques. Theories regarding the possibility that a common female ancestor existed in Africa about 200,000 years ago are discussed. A list of teaching aids is provided. (CW)

Describes a heuristic inquiry process attempting to better understand and appreciate a major aspect of religion influenced culture in the southern United States which has an impact on science education. Examines the intellectual and emotional viewpoints of scientists, science educators, and science teachers regarding the relationship between their…

This study: (1) comprehensively reviews previous research on the treatment of evolution in high school biology textbooks; (2) describes the treatment of evolutionary theory, including mention of creationist explanations of the development of life forms, in the most recent editions of 15 high school biology textbooks from the major publishers; and…

Reviews current research on a woman's chances of bearing twins and the genetic relationship, prenatal competition, and personality similarities between twins. In addition, the nature/nurture controversy is discussed in terms of evidence from studies of identical twins reared apart. Future studies are suggested to discover the ways twinning might…

This paper distinguishes between two ecological perspectives on organizational evolution: population ecology, which limits investigation to evolutionary change in established populations, and community ecology, which focuses on the rise and fall of populations themselves as basic units of evolutionary change. These perspectives produce contrasting…

Investigated was the influence of an instructional strategy to help freshmen undergraduate students overcome misconceptions regarding the nature of evolutionary theory. Discusses the strategy that included writing statements, small group discussion, teacher presentation, interactive lecture/discussion, and individual reflections. (YP)

Reports the development of an instrument for gathering information about the attitudes of Hong Kong secondary school teachers towards evolution. Describes the establishment, through criteria found in the literature, of a logical and systematic procedure for the validation of this Likert-type instrument. Tentatively found that the 15-item scale was…

Discusses the use of the human health risk assessment model as a basis for developing ecological risk assessment (ERA). For ERA, risk to individuals is less important than the survival of the population, with the exception of endangered species. Suggests that ERA take into account the relative reproductive value of the potentially impacted…

Described are animals that can filter their food out of the water. Various structures modified to strain plankton and small animals from water are detailed. The adaptive significance of these structures is discussed. (CW)

Presented are the arguments of two different points of view on the mass extinction of the dinosaurs. Evidence of extraterrestrial impact theory and massive volcanic eruption theory are discussed. (CW)

Analysis of subtopics of evolution in 22 high school biology textbooks shows a mean of 12 percent of total text devoted to evolution, with a decrease in attention from 1963 to 1983. Various text examples are presented to support the discussion, and implications for science teaching are addressed. (DH)

One of the most important myths in education is that of progress. The idea derives from a specifically Western messianic tradition and contains the belief in the growth and the development of an organism. That belief emerges from Greek and Hebraic thought, is modified in Christian theology, and then is secularized in science. The persistence and…

Discusses the teaching of evolution in New Zealand during the first half of the twentieth century. Reports that evolution instruction began formally in the 1920s but was withdrawn 30 years later amid protests. Observes that the teaching of evolution predated the 1920s in muted form. Describes the roles of broadcasting and religion in the dispute.…

Questions a hypothesis from creation science dealing with mammals. Claims that, when tested, the hypothesis fails in two ways. (TW)
