Pseudogenes are DNA sequences that resemble functional genes but seem to have no purpose. The presence of similar eta globin pseudogenes in humans and chimps has been used as an argument for common ancestry of the two species.
A collection of short commentaries on scientific papers published in 1993, covering topics such as evolution of the eye, phylogeny, "junk" DNA, giant fossil mammal, and creationists and radiocarbon dating. Published in Origins v. 21, n. 1.
The philosophical context in which biology is presented can make an important difference in its meaning for the student. The philosophical worldview of the biblical Christian is quite different from that of the non-Christian; thus, the biology teacher may have a profound influence on the development of worldview by the student.
This paper proposes that mutation and natural selection can produce biological change, but are not sufficient to explain the origins of biodiversity and complexity. Instead, the authors argue that genetic complexity is the result of intelligent design, and was at a maximum when life on Earth first came into being. Published in Origins v. 20, n. 2.
A review of the book, Blueprints: Solving the Mystery of Evolution. The book presents a rather uninformed critical response to creationism. Published in Origins v. 20, n. 1.
The "RNA World" hypothesis for the origin of life is implausible for several reasons, among them the difficulty of producing RNA naturalistically, its relative instability in water over time, the problem of chirality, and the insufficiency of RNA to form a living cell. Published in Origins v. 20., 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.
Several ideas have been proposed over the past two centuries to explain how organisms could have evolved through naturalistic processes. None of them seems viable, and it seems reasonable that creation should be considered as an explanation. Published in Origins v. 19, n. 1.

Dates calculated from radiocarbon and amino acid racemization show conflict. Analysis of the discrepancies and use of a radiocarbon conversion published earlier, some inferences are drawn regarding the cooling of the earth after the biblical flood. Published in Origins v. 18, n. 2.
Biomolecules decompose rapidly enough they are not expected to last for millions of years. Discovery of biomolecules in fossils is difficult to reconcile with the purported ages of these fossils, and suggests the ages are much younger, as expected in a biblical worldview. Published in Origins v. 18, 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, Arguments on Evolution: A Paleontologist's Perspective. This book is a defense against recent criticisms of neo-Darwinism. Published in Origins v. 18, n. 1.
In the early development of the theory of evolution by natural selection, two men stand out as having played a central role: Charles Darwin and Alfred Wallace. Both men traveled widely and were keen observers of nature. For both men, visits to islands played an important role in developing their understanding of nature. Darwin's visit to the Galapagos Islands is of special interest.
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.
