Historical Biogeography of South America, Part II: Fossil Vertebrates
This section focuses on South American fossil vertebrates, excluding marine fish. Extinct families will be emphasized here, as living families were considered in Part 1.

A review of the book, Mere Creation: Science, Faith & Intelligent Design. Published in Origins v. 25, n. 2.
Many families of vertebrates appear to have reached South America from the north, as would be expected as they dispersed from the ark after the worldwide flood. These include all the widespread families. Many other families are restricted to South America. Their biogeographical history is unknown.
What are genes? What role do they play in the function of organisms?
As a scientist, I frequently find myself taking a polemic stance in defense of creationism. In doing this, I easily lose sight nature as a revealer of its Creator. It is a pleasant change to contemplate my field of scientific interest, looking for insight about the Creator.
New information from whole-genome sequencing may contribute to creationist theory regarding the extent of change in species. Published in Origins v. 24, n. 2.
A collection of short commentaries on scientific papers published in 1997, covering topics such as comparative genomics, intelligent design as information, cloning mammals, Precambrian glaciation, radioisotope dating, Neanderthal DNA, the question of life on Mars, molecular evolution, transposable elements, paleomolecules, Krebs Cycle optimality, origin of life, fossil ants and embryos, dinosaur-bird comparisons, speciation in guppies, scientists and faith.

Review of the book, The Biotic Message: Evolution Versus Message Theory. Published in Origins v. 24, n. 1.
As biological knowledge has increased, the argument for design has been revived and expressed in more sophisticated ways, such as the argument from “irreducible complexity.” The existence of certain features that could not survive in intermediate stages is evidence of a Designer. It is also evidence of a Designer God who created by special intervention—Creation—and not through a continuous process such as evolution.
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.
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 1993-1994, 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 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.
Pseudogenes are DNA sequences that resemble functional genes but seem to have no purpose. The presence of similar eta globin pseudogenes in humans and chimps has been used as an argument for common ancestry of the two species.
