Summarizes events of a conference on evolutionary biology in Chicago entitled: "Macroevolution." Reviews the theory of modern synthesis, a term used to explain Darwinism in terms of population biology and genetics. Issues presented at the conference are discussed in detail. (CS)

Data are presented from families of monozygotic twin pairs which give evidence of genetic variance on the Block Design Test, a nonverbal measure of intelligence. Analyses of genetic and environmental effects on behavior are possible with this kind of information. (SA)

Discusses trends that have converged to transform our understanding of genetic and environmental influences on personality traits. Presents five main determinants of personality. (ZWH)

Reports that as a result of our increasing knowledge of the molecular biology of nitrogen fixation it might eventually be possible to increase the biological production of nitrogenous fertilizer from atmospheric nitrogen. (GS)

Discusses the sampling and data-collection techniques used to study the heights, intelligence levels, and aggression levels of XYY and XXY males. (MLH)

The body of data indicating sex differences in the brains of almost every mammalian family examined so far (rodents, birds, monkeys, and human beings) is reviewed. The differences in the hypothalamus, thalamus, corpus callosum, anterior commissure, and the hippocampus are described. (KR)

Lists informal definitions for 130 terms dealing with recombinant DNA research. (CS)

Describes recent research by Edward Steele appearing to support the Lamarckian theory of inheritance. Steele suggests that a mutant somatic cell favored by the environment will undergo clonal expansion. Altered genetic materials from these cells is then picked up by C-type viruses and inserted into the germ line genome. (CS)

Cyril Burt presented data in his paper that were in perfect agreement with a genetic theory of IQ and social class. A detailed analysis of these data reveals that they were fabricated from a theoretical normal curve, from a genetic regression equation, and from figures published more than 30 years before Burt completed his surveys. (Author/BB)

Reviews studies of the effects of lysergic acid diethylamide (LSD) on man and other organisms. Concludes that pure LSD injected in moderate doses does not cause chromosome or detectable genetic damage and is not a teratogen or carcinogen. (JM)

The question as to whether males and females have different kinds of intellectual abilities is addressed. The evidence that there are some differences in cognition and perception between men and women is reviewed. (KR)

Describes the diversity of plants. Outlines novel developmental and complex genetic processes that are specific to plants. Identifies approaches that can be used to solve problems in plant biology. Cites the advantages of using higher plants for experimental systems. (RT)

Discusses the applicability and advantages of using yeasts as popular and ideal model systems for studying and understanding eukaryotic biology at the cellular and molecular levels. Cites experimental tractability and the cooperative tradition of the research community of yeast biologists as reasons for this success. (RT)

Briefly reviews the early history of industrial microbiology and discusses industrial fermentation practices and the role of recombinant DNA in the fermentation industry. (SK)
