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.
Given the current database on fossil hominids, caution is warranted. Indeed, it would be premature to draw any definitive conclusions with regard to the origins of these organisms and their relationship to the Genesis record.

Published in Origins v. 23, n. 1.
A collection of short commentaries on scientific papers published in 1993-1995, covering topics such as biodiversity, gene transfer, genomics, ancient DNA, comparative immunoglobulin genes, Burgess Shale, fossil whales. Published in Origins v. 21, n. 2.
A review of the book, Messel: An Insight Into the History of Life and of the Earth. Messel is a pit in a deposit of oil shale in Germany with many finely preserved Eocene fossils. Published in Origins v. 22, n. 1.
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. 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, 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.
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.
The method of DNA-DNA hybridization has been applied to the relationships of birds, with some surprising results. The method is described and the results analyzed. While the results are quite interesting, there appear to be limits to the resolution of the method, and it seems inadvisable to depend upon this method alone when studying bird relationships. Published in Origins v. 14, n. 2.
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.
Staining of chromosomes reveals a pattern of banding that may be used for comparisons of different species. Similar species typically have similar banding patterns, although there are exceptions. Banding patterns may be interpreted as hypotheses of relationship but are not, in themselves, sufficient to settle such questions. Published in Origins v. 13, 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.
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.
