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.

the basic framework of the geologic column was founded by men with respect for Scripture, who, although not holding to conservative interpretations, opposed organic evolution. Published in Origins v. 9, n. 1.

The crucial questions on the relationship of Genesis and geology, of religion and geological science nearly all hinge in some way on one's understanding of the meaning and significance of the geologic column. It is important, therefore, to understand something of its origin as a system. Published in Origins v. 8, n. 2.

A review of the book, Puncuated Equilibria: The Tempo and Mode of Evolution Reconsidered. The new theory of punctuated equilibria acknowledges the gaps in the fossil record used by creationists as evidence against evolution, and explains them as due to the nature of the speciation process. However, the new theory applies only to gaps between species, and does not help with the problem of gaps between higher taxa. Published in Origins v. 5, n. 1.

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.
