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)

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)

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)

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

This study was designed to investigate the influence of a diversified instructional strategy to overcome misconceptions held by freshmen undergraduate students with respect to the nature of a scientific theory. The theory of evolution was selected because it is the most significant unifying theme within the discipline of biology. Two classes were…

Describes some of the contributions made by the field of paleontology to theories in geology and biology. Suggests that the two best examples of modern evolutionary paleontology relate to the theory of punctuated equilibria, and the possibility that mass extinctions may be cyclic. (TW)

Described is a symposium of Nobel laureates held in the summer of 1990 to discuss cosmology. Different views on the structure and evolution of the universe are presented. Evidence for different theories of cosmology is discussed. (CW)

Presented are the three main theories that describe the pattern of evolution of geographic variants of H. sapiens--the multiregional model, the out-of-Africa model, and the gene-flow or hybridization model. The contributions of geneticists, paleoanthropologists, and the history of fossils are included. (KR)

Discussed are the results of a test administered to nonmajor biology students on the topic of natural selection. The description of student conceptions, effects of instruction, and the effects of a belief in evolution are included. (KR)

Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)
