Uses anatomical studies to question the belief that australopithecines are on the main human evolutionary lineage. Includes numerous photographs and diagrams. (MA)

A review of research relating to the role of genetic factors in the hyperactive child syndrome is presented. Twin studies have been limited and adoption studies have been methodologically weak. Findings, however, are consistent and suggest that the genetic transmission hypothesis is plausible. (PHR)

Describes a second-year undergraduate practical course in quantitative genetics and biometrics, based upon computer-assisted learning (CAL); and discusses the educational benefits of the course, some problems encountered, and some implications of the extensive use of CAL. (Author/CMV)

A moderately retarded female adult with a 48,XXXX chromosome complement was found to have an extremely low ridge count in dermatoglyphic patterns. (Author)

Provides an introduction to the field of molecular evolution. Changes in genetic material and proteins help to time the stages of species evolution. (BB)

Written in response to an earlier article questioning certain aspects of evolution theory. Discusses ontogeny and phylogeny, the basis of evolution, chance or purpose in evolution, micro and macro-evolution, reversibility, and the evolution processes today. (MA)

Describes a very simple and effective method of DNA extraction from dried peas. Presents information on the Green Machine Science Education Center that promotes education in gene technology. (JRH)

Proposes local similarity pattern (LSP) as a new method for computing digital image similarity. Topics include optimizing similarity computation based on genetic algorithm; relevance feedback; and an evaluation of LSP on five databases that showed an increase in retrieval precision over other methods for computing image similarity. (Author/LRW)

Presents descriptions, and critiques seven books that cover racism, primarily from the hermeneutical viewpoint. Suggests that all seven were written in response to the "Bell Curve" (Herrnstein and Murray, 1994) and that they collectively argue that any new evidence of genetic determinism is inadmissible on the grounds that empirical work…

Uses characters from "Harry Potter and the Sorcerer's Stone" to teach about human pedigrees and presents an activity demonstrating how traits are passed to offspring. (YDS)

Advocates discussing human biological variation and race in science curricula. Explains how biologists use the term "race" and what that implies. (YDS)

Presents an assay on genetically modified (GM) foods, also called Frankenfoods, that demonstrates ways to evaluate a scientific metaphor and facilitate discussion on students' values regarding GM foods. (YDS)

This paper reports a clinical case of autism with a deletion on chromosome 2 in a young male with high functioning autism. The deletion seems to correspond with regions emerging from linkage studies. The paper proposes this chromosomal region as a possible candidate region in the search for autism genes. (Contains references.) (Author/DB)

Presents an activity in which students seek answers to questions about evolutionary relationships by using genetic databases and bioinformatics software. Students build genetic distance matrices and phylogenetic trees based on molecular sequence data using web-based resources. Provides a flowchart of steps involved in accessing, retrieving, and…

Examines ways in which students collaborate to construct, use, and revise conceptual and strategic knowledge as they solve complex genetics problems. Concludes that students used three types of knowledge during model revision: knowledge of genetics, knowledge of the process of model revision, and knowledge of their own problem-solving strategies…
