Published in Origins v. 23, n. 2.
Darwin's theory is in crisis. The academic ball is in its court. What will the Adventist ministry speak in response? The general community, for the time being at least, is listening.
A collection of short commentaries on scientific papers published in 1993-1994, covering such topics as parasite degeneration, convergence in diapsid reptiles, induced neoteny, genetic code, directed mutation in bacteria, radiohalos in a diamond, coelacanth phylogeny, marsupial phylogeny, origin of life, and fossil change in Jurassic rocks. Published in Origins v. 22, n. 1.
A collection of short commentaries on scientific papers published in 1993-1994, covering topics such as C. elegans genes, hotspots, stromatolites, insecticide resistance, and the Cambrian Explosion. Published in Origins v. 21, n. 2.
Pseudogenes are DNA sequences that resemble genes but do not appear to have a function. Similar pseudogenes in humans and chimps have been used to argue for common ancestry. However,if pseudogenes have a function in gene regulation the argument for common ancestry would be greatly weakened. Published in Origins v. 21, n. 2.
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.
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.
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.
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.
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.
A review of the book, Darwinism: The Refutation of a Myth. Written by a developmental biologist emphasizing the inadequacy of Darwinian evolutionary theory and advocating the importance of developmental processes in evolution. 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.
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.
