Insecticides should not be the only weapons of war used against pests; in addition to them, a strategy aimed at winning the millenial warfare should combine the tactical use of natural plant enemies, reinforced plant genetic qualities, and the application of adequate ecological techniques. (BL)

Describes a high school biology exercise in which a computer greatly reduces time spent on calculations. Genetic equilibrium demonstrated by the Hardy-Weinberg principle and the subsequent effects of violating any of its premises are more readily understood when frequencies of alleles through many generations are calculated by the computer.

That residents of Papago villages were less closely related in the 19th century than during recent decades is considered in historical and genetic perspectives. A preliminary version of this paper was read at the annual meeting of the American Anthropological Association, New York City, 1971. (FF)

Indicates each individual has a unique genetic history that determines much of his potential for excellence in a field. Educational programs should be planned with consideration of these individual variations. Instead of formulating plans for groups of people, concentration should be given to individuals in a group. (PS)

The second of two parts of a paper discussing the role of biology teachers in attempting to change public policy and attitudes toward exploitation of resources, population, and economic systems. (AL)

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)
