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.
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.
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.
A review of the book, Radiocarbon Dating: An Archaeological Perspective. Published in Origins v. 14, n. 1.
Claims that human and dinosaur footprints are found together in the Paluxy River of Texas have been retracted.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.
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.
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 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.
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 collection of short commentaries on scientifc papers published in 1983-1985, covering topics such as amino acid dating, problems in evolutionary theory, God and the New Physics, Scientists Confront Creationism, transgenic mammals, philosophy of science, and In the Minds of Men. Published in Origins v. 12, n. 2.
Most amino acids exist in two forms, commonly called "left" and "right." Living organisms use only "left" amino acids, but after death, the "left" amino acids begin changing to "right" forms, until there is an equal number of both. This suggests the possibility of using the amount of change as a measure of time, leading to the development of amino-acid dating. This dating of method does not confirm the results of other methods of dating. Published in Origins v. 12, n. 1.
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.
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.
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.
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.
Dates based on amino-acid racemization and uranium radioactive decay were quite different, with preference given to the radiometric dates. Published in Origins v. 8, n. 1.
