Possible reasons for the current resurgence of biological determinism are discussed. Deterministic arguments are classified as being based on the general human species or based on presumed differences among racial groups. The first type of argument is presented and some alternate interpretations proposed. (LS)

Describes a computer simulation of the evolution of species. This is a model for sorting out random and correlated paleontological events. (BB)

Discussed is the potential of vestigial structures and unexpressed developmental patterns from an organism's natural history to provide for rapid morphological change based on small genetic change which may call these suppressed attributes back into action in modified form. (RE)

Discusses various developments in both science and theology following the work of Charles Darwin on evolution. Differentiates between the facts regarding evolution and the theory of natural selection as a mechanism for evolutionary change. Warns that the differences between facts and theory have not been adequately emphasized by scientists. (TW)
