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.

A review of the book, Principles of Isotope Geology. An authoritative description of radioisotope dating and use of stable isotope ratios. 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.

This review examines Robert Gentry’s efforts to defend his model of creation built on the study or radiohaloes. Published in Origins v. 15, n. 1.

Some recent radiocarbon dates derived from sources assumed to be geologically very old give dates in the 40,000-year range. These relatively young dates may reflect the concentration of Carbon-14 in the antediluvian atmosphere. Published in Origins v. 15, n. 1.

A review of the book, The Geology of the Flood. The author advocates an age for the earth that is much longer than the biblical chronology and much shorter than the naturalistic chronology, which will make the book's position unsatisfactory to most readers. Published in Origins v. 14, n. 2.

The geochronological time scale of thousands of millions of years is based mainly on radiometric dating. On the other hand, some other time-dependent processes change at rates which challenge generally accepted geochronology. Published in Origins v. 13, n. 2.

A collection of short commentaries on scientific articles published in 1983, covering topics such as the history of Darwinism, integrity in science, evolution and thermodynamics, North American geology, Quaternary dating methods, origin of life, and the half-life of Technetium-99.

The chronological figures in the Septuagint version of Genesis 5 and 11 are different in different manuscripts, and appear to have been altered. This indicates the superiority of the Masoretic text for these data. Published in Origins v. 12, n. 1.

Radioisotope ages are calculated from ratios of certain atoms. The isotopic ratios can be precisely measured, but the calculation of age from that ratio involves assumptions that may vary depending on the philosophical orientation of the investigator. Published in Origins v. 10, n. 2.

A review of the book, Christianity and the Age of the Earth. The book presents a biased viewpoint against recent creation, but does point out some serious challenges that confront recent creationists. Published in Origins v 10, 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 picture that emerges from all the data that relate to cosmic chronology appears to be one of dynamic physical processes operating over extended periods of time, during the last 4.5 billion years of which discrete entities of the Solar System have been in existence. This suggests the word "earth" in Genesis 1 may refer to the land surface of the planet, and not to the planet itself. Published in Origins v. 8, n. 1.

Radiometric dates are subject to uncertainties due to the assumptions inherent in the method and to the effects of non-natural changes in the earth's crust on the third day of creation and during the biblical Flood. Published in Origins v. 4, 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.

A review of the book, Scientific Creationism (Public School Edition). A science textbook with creationist sympathies would be a valuable contribution. This book, although many will find it useful, comes short of the goal. Published in Origins v. 4, n. 1.
