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

Microorganisms can exist in rocks several kilometers below the surface of the earth. Recently a number of reports indicate that these organisms are much more common than previously surmised and that vast regions of the underworld may be inhabited. Published in Origins v. 19, n. 2.

A collection of short commentaries on scientifc papers published in 1991, covering topics such as phylogenies, origin of life, Precambrian fossils, polar dinosaurs, fossil turtles, Lysan finch, ecological gradients and the fossil record. Published in Origins v. 18, n. 1.

A review of the book, The Origin of Species Revisited: The Theories of Evolution and of Abrupt Appearance. This is an attempt to meet the legal requirement that religion not be introduced into the science class by using the term "abrupt appearance" rather than a term implying a specific process such as creation or evolution. Published in Origins v. 17, n. 2.

A review of the book, Wonderful Life: The Burgess Shale and the Nature of History. The book describes the history of discovery of the Burgess Shale fossils and their classification. Published in Origins v. 17, n. 1.

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.

Fossil reefs from Silurian and Devonian sediments in the Great Lakes region of the United States are compared with a modern reef in Florida. The fossil reefs differ significantly from modern reefs by lacking the framework of corals that are characteristic of modern reefs. Instead, the fossil reefs look more like carbonate mud mounds. Published in Origins v. 14, n. 2.

Claims that human and dinosaur footprints are found together in the Paluxy River of Texas have been retracted. Creationists must be careful to check the validity of the claims they make. Published in Origins v. 14, n. 1.

Archaeopteryx has traits of both birds and reptiles, and has long been accepted as a fossil intermediate. Recently, the charge has been presented that Archaeopteryx is a forgery rather than a legitimate fossil. This has resulted in much research into the nature of the fossils of Archaeopteryx. Published in Origins v. 13, 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.

In the early sixties, Clifford Burdick claimed to have discovered pollen of modern plant in Precambrian rocks. Dr. Chadwick has not been able to confirm Burdick's findings, however, he does point out that this type of irregularity has been reported by several traditional geologists and that these findings pose a challenge to one of evolution's fundamental tenets.

A fossil bird from Argentina is now regarded as the largest known flying bird. Published in Origins v. 7, n. 2.

Changes in the distributions of fossil beetles in Pleistocene sediments provide further evidence that significant climatic change has taken place in post-flood times. Published in Origins v. 7, n. 2.

The normal accumulation of organic debris and the subsequent formation of humus and true soil which proceeds relentlessly on modern growth surfaces does not readily account for several of the phenomena seen in the organic levels of Yellowstone. Published in Origins v. 6, n. 2.

The Coconino Sandstone has traditionally been interpreted as wind-deposited, but fossil trackways in this formation point to underwater deposition. 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.

The Glen Rose region of the Paluxy River does not provide good evidence for the past existence of giant men, nor does it provide evidence for the coexistence of such men and the giant dinosaurs. Published in Origins v. 2, n. 2.

A tiny marine worm, Spirorbis, constructs a calcareous tube, and is often found attached to shells and debris in the ocean. Fossil Spirorbis are sometimes common in coal beds. Some have suggested Spirorbis lived in fresh-water habitats in the past, but this is highly unlikely. It is more likely that coal formed in marine waters during the Flood.
