Egnor’s Unanswered Questions
What happens when a professor of neurosurgey who is a Darwin-skeptic and just happens to be a brain surgeon visits a popular Darwinist blog? He leaves with unanswered questions. Last week Rob Crowther highlighted how Dr. Michael Egnor visited Time magazine’s science blog where a reporter admitted his Darwinist bias and was unable to answer Egnor’s question: “how much new information can Darwinian mechanisms generate?” Egnor is professor of neurosurgery and pediatrics at State University of New York, Stony Brook and an award-winning brain surgeon who has been named one of New York’s best doctors by New York Magazine. Egnor recently took his questions to P.Z. Myers’ popular science blog Pharyngula, where Egnor continues–unanswered–to press Darwinists for how Darwinian mechanisms Read More ›
Evolving Embryo Drawings at London’s The Science Museum Website
Some Darwinists have recently tried to rewrite history, claiming that no one uses Haeckel’s embryo drawings anymore. But on December 2, 2006, Truth in Science, a British group which supports intelligent design, reported that London’s The Science Museum had colorized versions of Haeckel’s embryo drawings on their website. Before that time, the museum’s website had used drawings that looked like this: (Graphic provided courtesy of David Anderson of BCSE-Revealed.) Clearly Haeckel’s faked drawings were promoted by the museum as of December, 2006 as evidence for evolution. In fact, Truth in Science reported that the caption also read, “It seems that an efficient way of marking out the body plan arose millions of years ago, and has remained virtually unchanged throughout Read More ›
The Origin of Life: Not so Simple (Part III)
This post will provide a final discussion of an article in Scientific American entitled “A Simpler Origin for Life” by Robert Shapiro. Part I explained why the Miller-Urey experiment and the DNA-first hypothesis is deficient. In Part II, I explained Shapiro’s apt criticisms of the RNA-world hypothesis. Those who have abandoned the RNA-world hypothesis still seek a self-replicating molecule to qualify as the climax of chemical-origin of life scenarios–the “pre-RNA world.” However, Shapiro observes not only that “no trace of this hypothetical primal replicator and catalyst has been recognized so far in modern biology,” but also that “the spontaneous appearance of any such replicator without the assistance of a chemist faces implausibilities that dwarf those involved in the preparation of Read More ›
The Origin of Life: Not so Simple (Part II)
Writing in Scientific American Robert Shapiro recounts many criticisms of popular models for the chemical origin of life. Part I recounted why many origin of life theorists reject the possibility that DNA was the first genetic molecule. As noted, Shapiro even takes aim at those who suggest that the Miller-Urey experiment chemistry was important for forming prebiotic molecules on meteorites because studies of these meteorites show “a bias toward the formation of molecules made of fewer rather than greater numbers of carbon atoms, and thus shows no partiality in favor of creating the building blocks of our kind of life.” Due to these deficiencies, Shapiro then notes that increasing numbers of prebiotic chemists now turn to RNA as the first Read More ›
The Origin of Life: Not so Simple (Part I)
In an article titled “A Simpler Origin for Life” — a title which hides the implication of the article, Robert Shapiro, writing in Scientific American, highlights many problems with chemical origin of life scenarios. Shapiro quotes Richard Dawkins on his worship of the first self-replicating molecule and says “[a]t some point a particularly remarkable molecule was formed by accident. We will call it the Replicator.” (emphasis in original) That’s “Replicator” with a capital “R“. But, as Shapiro explains, the conventional explanation is not nearly so simple: Unfortunately, complications soon set in. DNA replication cannot proceed without the assistance of a number of proteins — members of a family of large molecules that are chemically very different from DNA. Proteins, like Read More ›
