This is an attempt to develop a methedology for converting carbon-14 ages into real time in a biblical context that fixes the date of the global flood at about 5,000 years ago. A table is provided of sample converted ages. Published in Origins v. 17, n. 2.
A review of the book, Absolute Age Determination. An authoritative description is provided of the methods of age-dating used to estimate the age of the earth. Published in Origins v. 17, n. 2.
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.
The purpose of this paper is to explore some of the areas of contact between human personality theory and the Christian understanding of the image of God.
The available data on C-14 age profiles indicate that the characteristic relationship is nonlinear in a direction which suggests that the C-14/C-12 ratio was less in the past than it is now. 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.
A review of the book, Radiocarbon Dating: An Archaeological Perspective. 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 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.
Vitamin C is important in vertebrate physiology, but is acquired in different ways. Some mammals and perching birds do not synthesize it and must get it in their diet. Most other mammals and birds synthesize vitamin C, in their kidneys, the livers, or both. The pattern of synthesizing sometimes follows taxonomic patterns and sometimes not. 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.
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 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.
A number of factors could affect the relation of C-14 concentration to real time. The author discusses the effects on C-14 dates of cosmic ray intensity, geomagnetic field strength, water vapor concentration, and dilution by the biosphere carbon. Published in Origins v. 6, n. 1.
A review of the book, Principles of Isotope Geology. This is an authoritative textbook on radioisotope dating that provides useful background information, regardless of philosophical persuasion. Published in Origins v. 6, n. 1.
Portions of the DNA information are not present in mRNA transcribed from the DNA, in plants and animals, as opposed to bacteria. The DNA sequences that are missing in the m-RNA are called introns, and seem to be widespread. Published in Origins v. 5, n. 1.
