Any of the proposed resolutions to the conflict between radiometric dating and biblical chronology has problems. The pros and cons of each need to be considered.

Radiometric dating is an interpretive science. The complex chemical and physical processes taking place within Earth's mantle and crust are neither completely known nor understood. This is especially true when the radioactive isotope parameters are considered.

The doctrine of Creation occupies an important place in Seventh-day Adventist message and mission. The reason for this is twofold: First, Adventists believe in a fiat Creation; and second, they are committed to the proclamation of the three angels’ message of Revelation 14.

A collection of short commentaries of scientific papers published in 1996, covering topics such as biogeography, Milankovitch cycles, turtles, degeneration by mutation, fossil sharks, fossil bird, ichthyosaurs, speciation rates in cichlid fish, plate tectonic anomaly. Published in Origins v. 23, n. 2.

Various examples adequately establish that a radioisotope age does not necessarily have a real-time significance. A relationship of a radioisotope age with real-time must be based on an interpretation.

Given the current database on fossil hominids, caution is warranted. Indeed, it would be premature to draw any definitive conclusions with regard to the origins of these organisms and their relationship to the Genesis record.

A collection of short commentaries on scientific papers published in 1996, covering topics such as Homo erectus, the Permian mass extinction, mutations in Chernobyl rodents, dropstones, yeast genome, Heart Mt detachment, carbonate cycles, eye development gene, RNA World, Archaeopteryx, Cambrian chordate, turtles, stromatolites, and pseudogenes.

Literature Reviews

A review of the book, Darwin's Black Box. Published in Origins v. 23, n. 1.

Darwin's theory is in crisis. The academic ball is in its court. What will the Adventist ministry speak in response? The general community, for the time being at least, is listening.

A collection of short commentaries on scientific papers published in 1993-1995, covering topics such as biodiversity, gene transfer, genomics, ancient DNA, comparative immunoglobulin genes, Burgess Shale, fossil whales. Published in Origins v. 21, n. 2.

A review of the book, The Quest for Life in Amber. Published in Origins v. 21, n. 2.

Ancient fossil reefs are considered to be a challenge to the biblical concept of creation. But do these fossil reefs really negate the biblical account of beginnings? Published in Origins v. 21, n. 2.

A collection of short commentaries on scientific papers published in 1993-1994, covering such topics as parasite degeneration, convergence in diapsid reptiles, induced neoteny, genetic code, directed mutation in bacteria, radiohalos in a diamond, coelacanth phylogeny, marsupial phylogeny, origin of life, and fossil change in Jurassic rocks. Published in Origins v. 22, n. 1.

A review of the book, Messel: An Insight Into the History of Life and of the Earth. Messel is a pit in a deposit of oil shale in Germany with many finely preserved Eocene fossils. Published in Origins v. 22, n. 1.

Statistical analysis of the various dendrochronology master sequences that were published prior to 1985 indicates that the master sequence developed by Ferguson has unique auto-correlation features, and that its use is definitely questionable. Published in Origins v. 22, n. 1.

The relationship of carbon-14 dates with biblical chronology is improved by recognizing that c-14 concentrations have not yet reached equilibrium between the upper biosphere and the deep ocean. Published in Origins v. 21, n. 2.

A collection of short commentaries on scientific papers published in 1993-1994, covering topics such as C. elegans genes, hotspots, stromatolites, insecticide resistance, and the Cambrian Explosion. Published in Origins v. 21, n. 2.

Pseudogenes are DNA sequences that resemble genes but do not appear to have a function. Similar pseudogenes in humans and chimps have been used to argue for common ancestry. However,if pseudogenes have a function in gene regulation the argument for common ancestry would be greatly weakened. Published in Origins v. 21, n. 2.
