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.

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.
A review of the book, Evolution: A Theory in Crisis. Evolutionary theory faces many contrary lines of evidence and is in need of major changes. Published in Origins v. 13, n. 1.
A review of the book, Abusing Science: The Case Against Creationism. The book gives responses to criticisms of evolutionary theory by creationists, and presents several criticisms of creation theory. Published in Origins v. 12, n. 2.
A review of the book, The Great Evolution Mystery. Darwinism is entirely inadequate to explain evolution, so some other purely naturalistic mechanism is needed. Published in Origins v. 12, n. 1.
Species in the same family or genus may have very similar chromosomal banding patterns, but with apparent rearrangements of parts of some chromsomes. Such rearrangements may contribute to speciation in mammals by interfering with meoisis. Published in Origins v. 11, n. 2.
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.
Review of the article, Biologists, Help! An appeal by a secular scholar for evolutionists to explain why so many fundamental suppositions of evolutionary theory are so poorly supported by the data. Published in Origins v. 5, 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.
Similarities in structure, or homologies, are what one would expect if all of life had been designed by a single Creator. Homologies are not evidence for evolution. Published in Origins v. 3, n. 2.
Several scientists have acknowledged that the evidence for evolution is deficient, and new approaches and information are needed. Published in Origins v. 3, n. 1.
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.
A review of the book, Darwin Retried: An Appeal to Reason. the evidence for evolution is so weak it should not be considered a valid theory. Creation is not favored either. Published in Origins v. 1, n. 2.
Thousands of well-preserved Cambrian fossils are found in the Burgess Shale of Alberta, Canada. These Cambrian fossils are complex and diverse, in contradiction to the expectations of evolutionary theory. Published in Origins v. 1, n. 1.
