Commonality in culture, environment, home influences, does not produce commonality in intelligence. Suggestion offered that genetics may be overriding faction. (Author)

Fifth article in a sequence that originated with a controversial article by Arthur R. Jensen (1969) criticized by Richard J. Light and Paul V. Smith (1969) and countercriticized by the author (1971). (SE)

Discusses basic concepts in human and medical genetics and their relevance to the field of adoption. Describes genetic counseling and suggests that adoption agencies use such services. (Author)

The equality of Negro and Caucasian intelligence is questioned. (CK)

A study of mental ability and reading comprehension as a function of sex and race in Trinidad contradicts a large body of North American literature advocating a hereditary-related Black intellectual inferiority. Results suggest that intellectual differences between racial groups in a given society reflect variables associated with racial…

Provided is a microcomputer program listing which demonstrates the effects of selection on gene frequencies. A very brief description of the program is also provided. (JN)

Because many people still believe that specific, identifiable genes dictate the level of human intelligence and that the number/quality of these genes can be evaluated, presents evidence from human genetics (related to nervous system development) to counter this view. Also disputes erroneous assumptions made in "heritability studies" of human…

Among the many theories attempting to explain sex differences in spatial ability, one of the most highly researched is the X-linked recessive gene theory. This is a review of the major research done on that theory and shows the conflicting nature of the results. (Author)

Reasons for studying human genetics are discussed. These include philosophical reasons, reasons of health, and social reasons. While content, interpretation, and emphasis of human genetics study will vary depending upon schools, teachers, and developmental stages of students, it is suggested that teachers address these three domains. (Author/JN)

Information from scientific journals on the biology of skin color is discussed. Major areas addressed include: (1) biology of melanin, melanocytes, and melanosomes; (2) melanosome and human diversity; (3) genetics of skin color; and (4) skin color, geography, and natural selection. (JN)

Results from a human genetics/bioethics needs assessment questionnaire (N = 124 out of 300) mailed to Indiana health teachers are reported. Genetic topics and human genetic diseases/defects included in health science instruction are listed in two tables. Responses to 16 science/society statements (and statements themselves) are also reported. (SK)

Reviews the benefits and hazards of genetic engineering, or "recombinant-DNA" research. Recent federal safety rules issued by NIH which ease the strict prohibitions on recombinant-DNA research are explained. (CS)

Outlines a humanities course which focuses on six topics: medical ethics, nuclear power, genetic engineering, drugs, energy, and cognitive abilities. Course requirements and units are described. (DC)
