Several ideas have been proposed over the past two centuries to explain how organisms could have evolved through naturalistic processes. None of them seems viable, and it seems reasonable that creation should be considered as an explanation. Published in Origins v. 19, n. 1.

A collection of short commentaries on scientific papers published in 1992, covering topics such as gene conversion, paleosols, magma mixing, molecular evolution, paleoecology, Precambrian algae, Cambrian explosion, conodont fossils, fossil birds and bird tracks, fossils, and taphonomy. Published in Origins v. 19, n. 1.

A recent survey shows about 9% of the population accepts the viewpoint of naturalistic evolution, about 40% accept divinely guided evolution, about 47% accept a recent creation of humans, and about 4% registered they don't know. These results are nearly the same as a similar survey taken three years before. Published in Origins v. 18, n. 2.

Assumptions may eventually become so widely accepted they are no longer recognized as assumptions but take the status of truth. Two examples that relate to origins are assumptions of abiogeneis and long ages. These points should not be assumed but tested if one wants to discover truth. Published in Origins v. 18, n. 1.

A collection of short commentaries on scientifc papers published in 1991, covering topics such as phylogenies, origin of life, Precambrian fossils, polar dinosaurs, fossil turtles, Lysan finch, ecological gradients and the fossil record. Published in Origins v. 18, n. 1.

A review of the book, Arguments on Evolution: A Paleontologist's Perspective. This book is a defense against recent criticisms of neo-Darwinism. Published in Origins v. 18, n. 1.

A review of the book, Portraits of Creation: Biblical and Scientific Perspectives on the World's Formation. This is a sophisticated criticism of creation science, and some of the points should be taken to heart by creationists. However, it fails to recognize the good quality of recent creationist literature. Published in Origins v. 18, n. 1.

In the early development of the theory of evolution by natural selection, two men stand out as having played a central role: Charles Darwin and Alfred Wallace. Both men traveled widely and were keen observers of nature. For both men, visits to islands played an important role in developing their understanding of nature. Darwin's visit to the Galapagos Islands is of special interest.

A collection of short commentaries on scientific papers published in 1989-1990, covering topics such as end-Permian extinction, fossil plant DNA, phylogenies, Triassic paleobiogeography, fossils, dinosaurs, science, radiocarbon dating, rift lake cichlids, fossils out of sequence, and mass extinction patterns. Published in Origins v. 17, n. 2.

A collection of short commentaries on scientific papers published in 1989, covering topics such as philosophy of science, mantle plumes, molecular clock, plant phylogeny, paleobiogeography, fossil reptile, Ediacaran fossils, rapid change in birds and insects, rapid oil formation, molecular evolution, population bottleneck in Drosophila, and mass mortality of sea urchins. Published in Origins v. 17, n. 1.

The purpose of this paper to compare and contrast scientific and religious paradigms and their communities. Similarities include the fact that it is possible to analyze both in terms of the formal components of a paradigm, that a community is essential to both traditions, and that the intersubjective testing and universality, along with data and experience, are important for "rational objectivity" in both communities.

A collection of short commentaries on scientific papers published in 1997, covering topics such as Darwin's finches, teleology, exon shuffling, flood geology, origin of life, dinosaurs, theistic evolution, radiocarbon dating, fossil invertebrates, and monotreme chromosomes. Published in Origins v. 16, n. 2.

A review of the book, Rates of Evolution. Published from a symposium on evolution. Published in Origins v. 16, n. 2.

A collection of short commentaries on scientific papers published in 1988-1989, and covering topics such as green sea turtle migration, adaptive mutation in bacteria, DNA-hybridization phylogenetics, biogeography of Krakatau Island, molecular phylogeny of animals, molecular evolution of plant mitochondria, molecular clock in plants, problems in evolution, and teaching science.

A review of the book, Darwinism: The Refutation of a Myth. Written by a developmental biologist emphasizing the inadequacy of Darwinian evolutionary theory and advocating the importance of developmental processes in evolution. Published in Origins v. 16, n. 1.

A collection of short commentaries on scientific papers published mostly in 1988, covering topics such as human origins, anti-evolutionary literature, mutations, geology and art, paleomagnetism, dinosaurs, origin of the universe, and plate tectonics. Published in Origins v. 16, n. 2.

Disagreements among creationists can lead to better understanding and improvement in creation thinking, and should not be ignored or regarded as an embarrassment. Creationists learn the same way as everyone else, and disputations are expected in the search for truth. Published in Origins v. 15, n. 1.

Reactions to the articles, Of Dinosaurs and Men, and to the editorial Science: A Good Place to Begin. Published in Origins v. 15, n. 1.

The method of DNA-DNA hybridization has been applied to the relationships of birds, with some surprising results. The method is described and the results analyzed. While the results are quite interesting, there appear to be limits to the resolution of the method, and it seems inadvisable to depend upon this method alone when studying bird relationships.
