Discusses how genetic data on present human population relationships and data from the Pleistocene fossil hominid record are being used to compare two contrasting models for the origin of modern humans. (TW)

The relationship between Eastern and Western languages is explored. Possible origins and the spread of language over the Eurasian land mass are discussed. (CW)

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)

Discusses the teaching of evolution in New Zealand during the first half of the twentieth century. Reports that evolution instruction began formally in the 1920s but was withdrawn 30 years later amid protests. Observes that the teaching of evolution predated the 1920s in muted form. Describes the roles of broadcasting and religion in the dispute.…

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

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)

Discusses some of the similarities and differences between the attitudes of Japanese and American citizens toward science. Reports on major discrepancies between the two populations' views about such things as evolution, the development of new plants and animals, and the effect of rocket launchings on the weather. (TW)

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)
