Most animal phyla, including those with soft bodies, appear in Cambrian sediments, in a pattern called the Cambrian Explosion. This pattern is exactly opposite of that predicted by Darwin's theory, but is readily explained in the context of creation and a global catastrophe. Published in Origins n. 53.

Published in Origins v. 25, n. 2.

One of the most interesting challenges in understanding Earth history is explanation of the order in the fossil record. Study of fossil patterns and trends should help improve our understanding of the underlying processes. Published in Origins v. 23, 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 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.

A collection of short commentaries on scientific papers published in 1991, covering topics such as Permian trees, molecular genetics, epigenetics, inheritance of paternal mtDNA, water and formation of petroleum, water in mantle rocks, impacts, Ordovician volcanism, molecular phylogenies of ratites, termites, cichlids and sabertooths, osteocalcin in dinosaur bones, fossil flowers, origin of life, Precambrian predation, stromatolites, Cambrian Explosion, quality of fossil record, rapid speciation, tree biogeography, Miocene ape, fossil dermopteran, Asian marsupial, dinosaurs, mammal-like reptile.

A review of the book, The Early Evolution of Metazoa and the Significance of Problematic Taxa. Published in Origins v. 19, n. 2.

The unnatural mixture and the rapid stratigraphic shifts of fauna seem to require catastrophic water transport into the area. The large geographic extent precludes a local event. Creationists suggest that a world-wide flood could produce results as seen in the Santana Formation and is a better explanatory model.

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

Most punctuated equilibria theories explain why proposed exceptions tend to be in the Upper Cenozoic. Punq Eq Creation Style, however, not only predicts the stasis and abrupt appearance of species, but it also predicts that exceptions will be found in the Upper Cenozoic among forminifera. Because of its greater explanatory power, PECS teoyr is superior to other PE theories. Published in Origins v. 16, n. 1.

Foraminifers exemplify many of the problems of fitting the fossil record into a short chronology, including thousands of named species and apparent evolutionary sequences. Any short-time creationist model must be able to explain these features. Published in Origins v. 15, n. 1.

Bird and mammal footprints are most common in the same stratigraphic intervals where their body fossils are common. However, reptile and amphibian tracks are more common in stratigraphic layers lower than their body fossils. Published in Origins v. 9, n. 2.

Experimental evidence shows that wood can petrify in a few years or less when immersed in mineral-rich water. Published in Origins v. 5, n. 2.

A review of the book, The Two-taled Dinosaur. Dinosaurs, and other fossils, can be interpreted in more than one way. Published in Origins v. 4, n. 2.

Growth lines found in several invertebrates show promise of serving as a basis for many avenues of investigation. Their value as an independent method for geochronometry is presently questioned, while other methods of using them are being developed. Published in Origins v. 1, n. 2.
