Tree of Life

It’s always easier to refute your opponent’s position by replacing it with an outlandish straw man. The most recent issue of the Journal of Eukaryotic Microbiology contains a paper by Guillermo Paz-y-Miño of University of Massachusetts Dartmouth and Avelina Espinosa of Roger Williams University, titled “Integrating Horizontal Gene Transfer and Common Descent to Depict Evolution and Contrast It with ‘Common Design’” that takes this approach to attacking intelligent design (ID). As suggested by the title, the article attempts to critique the argument that similar features in diverse organisms can be explained by common design. It cites to both a 1996 paper by Paul Nelson in Biology and Philosophy and a response to Francis Collins published by myself and Logan Gage Read More ›

A recent article in ScienceDaily titled “ Introns Nonsense DNA May Be More Important to Evolution of Genomes Than Thought,” actually demonstrates nothing like Darwinian evolution. Introns are stretches of DNA within genes in Eukaryotes that do not code for proteins. But they aren’t functionless and can play important roles in splicing together proteins. According to the ScienceDaily article: “The scientists also found what appear to be “hot spots” for intron insertion — areas of the genome where repeated insertions are more likely to occur. This implies the occurrence of convergent genetic evolution of introns at specific locations, or as the article repeatedly puts it, “parallel intron gains.” The study’s principal investigator, Michael Lynch, was clear about the implications: Michael Read More ›

Molecules Contradict Morphology A final way that evolutionists overstate the evidence for common descent is by claiming that molecular phylogenies have confirmed or buttressed phylogenies based upon morphology. For example, in his book Galileo’s Finger, Oxford University scientist Peter Atkins discusses evolution and boldly states, “The effective prediction is that the details of molecular evolution must be consistent with those of macroscopic evolution,” further claiming, “That is found to be the case: there is not a single instance of the molecular traces Read More ›

Homology in Crisis As Mayr suggests, there are other examples where genetic similarity appears in unexpected places. Biologically functional similarity that is thought to be the result of inheritance from a common ancestor is called “homology.” The concept of “homology” has been thrown into a crisis via observations, like those of Mayr, that the same genes control the growth of non-homologous body parts. Pax-6 is just one example. Another is the fact that the same gene controls the development of limbs in Read More ›

Extreme Genetic Convergent Similarity: Common Design or Common Descent? If common descent is leading to so many bad predictions, why not consider the possibility that biological similarity is instead the result of common design? After all, designers regularly re-use parts, programs, or components that work in different designs (such as using wheels on both cars and airplanes, or keyboards on both computers and cell-phones). One data-point that might suggest common design rather than common descent is the gene “pax-6.” Pax-6 is one Read More ›

The Molecular Evidence When speaking to the public, evolutionists are infamous for overstating the evidence for universal common ancestry. For example, when speaking before the Texas State Board of Education in January, 2009, University of Texas evolutionist biologist David Hillis cited himself as one of the “world’s leading experts on the tree of life” and later told the Board that there is “overwhelming agreement correspondence as you go from protein to protein, DNA sequence to DNA sequence” when reconstructing evolutionary history using Read More ›

Evolutionists often claim that universal common ancestry and the “tree of life” are established facts. One recent opinion article in argued, “The evidence that all life, plants and animals, humans and fruit flies, evolved from a common ancestor by mutation and natural selection is beyond theory. It is a fact. Anyone who takes the time to read the evidence with an open mind will join scientists and the well-educated.”1 The take-home message is that if you doubt Darwin’s tree of life, you’re Read More ›

In the recent Intelligent Design issue of Salvo Magazine, Logan Gage and I co-authored a piece titled, “Barking up the Wrong Tree,” which assesses popular arguments for universal common ancestry. From the outset, it should be stated that neither Logan Gage nor I feel that universal common ancestry is necessarily incompatible with theism. In a twist of poor logic, however, that fact is apparently sufficient for some theists to think that they should therefore accept common ancestry. Logan Gage and I observe that “when discussing science and faith, it is vital to ask the right questions. Queries beginning with the words ‘Could God have…?’ tend to be unenlightening. The much more revealing question is ‘What does the evidence say?’” Thus Read More ›

In late 2005, three biologists published a study in Science which concluded, “Despite the amount of data and breadth of taxa analyzed, relationships among most [animal] phyla remained unresolved.” In 2008, the relationships among animals are still controversial. A recent news release at Science Daily highlights a new study, “Tree Of Animal Life Has Branches Rearranged.” The story reports, “The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species.” According to the article, the study yielded surprising results: “Comb jellyfish — common and extremely fragile jellies with well-developed tissues — appear to have diverged from other animals even before the lowly sponge, which has Read More ›

I recently picked up Galileo’s Finger: The Ten Great Ideas of Science by Oxford chemist Peter Atkins. It’s a 2003 book, and on the plus side, it offers enjoyable and concise explanations of many important scientific theories, including some lucid diagrams explaining Einstein’s ideas about relativity. In his chapter on evolution, Atkins boldly states, “The effective prediction is that the details of molecular evolution must be consistent with those of macroscopic evolution.” (pg. 16) I’m willing to accept that “prediction.” However, Atkins unfortunately goes on to dramatically overstate the evidence for molecular evolution by asserting, “That is found to be the case: there is not a single instance of the molecular traces of change being inconsistent with our observations of Read More ›
