Phillip Johnson on Dogmatic Signs
This month’s edition of Touchstone Magazine has a great column by the godfather of intelligent design, Phillip Johnson, offering his review of Stephen Meyer’s Signature in the Cell and his take on why the book has been met with such an uproar in the blogosphere: In another way, however, it is peculiar that there is such a furious and often ill-informed objection to a learned volume that isn’t even about the theory of biological evolution. The book advances well-reasoned arguments based on solid evidence about a prior problem — the origin of the cell’s information content — concerning which most scientists would concede that they know very little. The one thing that many of these scientists think they do know Read More ›
The Human Genome Project Ten Years Later
Scientific American recently reported on what has transpired since the completion of the Human Genome Project ten years ago. When the HGP was first announced in 2000, many scientists said that it would be the key to understanding disease and for developing cures. Ten years later, however, this has not been the case. The human genome project has aided in developing better research and technology, particularly in our abilities to sequence genes. It has also shown us that much of what we once considered junk DNA isn’t really junk at all. (See here, here, here, and here for past ENV discussions on junk DNA). However, scientists are coming to a sobering conclusion that perhaps their models and assumptions on the Read More ›
Francis Collins, Evolution and “Darwin of the Gaps”
Francis Collins is one of the world’s most prominent theistic evolutionists, and now a prominent piece of President Obama’s government. In this clip, God and Evolution contributors and other scholars respond to Francis Collins’ defense of theistic evolution in his book The Language of God. In his book The Language of God: A Scientist Presents Evidence for Belief (2006) and other writings and interviews, Collins has described the paths that led him from atheism to religious belief and from an impatience with “messy” biology and a preference for the pristine realms of physics and chemistry to a fascination with DNA, RNA, and “gene-hunting.” Much of Collins’s case for Darwinian evolution is based on so-called “junk DNA.” This is the part Read More ›
Affinity Maturation and Somatic Cell Hypermutation: Intricately Controlled Processes that are Unlike Mutation and Selection
[Editor’s Note: This is part three of a six-part response from microbiologist Don Ewert to Kathryn Applegate’s arguments that the vertebrate adaptive immune system is an example of Darwinian evolution in action. Part one can be found here, and part two is here.] The second stage of B cell receptor development is initiated when a foreign protein enters our body and is detected by a circulating B cell using its cell surface antigen receptor (BCR). The BCRs that recognize these antigens improve their affinity (binding capacity) for the antigen by entering into a fine-tuning process called affinity maturation. This process ensures that highly effective antibody receptors are produced and released as cell-free antibodies into the circulation as the B cell Read More ›
Generation of Antibody Diversity is Unlike Darwinian Evolution
[Editor’s Note: This is part two of a response from microbiologist Don Ewert to arguments from BioLogos’s Kathryn Applegate that our immune system shows the creative power Darwinian evolution. Part one can be found here.] The intricate mechanism for generating antibody diversity from very few germline (existing) genes was discovered over thirty years ago. It involves shuffling gene segments and then fusing them to produce new combining sites for the antibody receptor displayed on individual B cells. How much of this process is pre-programmed and how much is random? Is this an example of the use of a “‘blind’ system to sustain and preserve life,” as Kathryn Applegate suggests? The evidence from decades of research reveals a complex network of Read More ›
