Atheist philosopher A.C. Grayling, whose debate with Peter S. Williams I wrote about yesterday, recently published a new book, The God Argument: The Case Against Religion and for Humanism. I was particularly interested in reading Chapter 11, which is devoted to the subject of creationism and intelligent design. The chapter contains so many errors and is so poorly researched … [Read more...]
British Atheist Philosopher A.C. Grayling Is Confused About Intelligent Design
The video above features a short excerpt from a debate between well-known atheist philosopher A.C. Grayling (famous for conveniently "forgetting" having debated William Lane Craig) and Christian philosopher Peter S. Williams. Their subject: the fine-tuning of the universe's initial conditions to support complex life, bearing on the case for intelligent design. Williams … [Read more...]
Bacterial Cell Division and Peptidoglycan Synthesis: An Evolutionary Enigma
The video above shows the process by which bacterial cells reproduce themselves. Looks simple, doesn't it? It's only a colony of cells elongating before splitting in two. Don't be fooled -- appearances can be deceiving. As is so common throughout biology, the apparent simplicity at the macro level masks remarkable complexity at the micro or molecular level. In eukaryotes, cell … [Read more...]
Two of the World's Leading Experts on Bacterial Flagellar Assembly Take on Michael Behe
I've been reading the recently published book Microbes and Evolution: The World that Darwin Never Saw, which combines my two primary areas of interest: microbiology and evolution. Chapter 38 of the book is written by Kelly Hughes and David Blair of the University of Utah, two of the world's leading experts on bacterial flagellar assembly. Having followed the work of Kelly … [Read more...]
Unwinding the Double Helix: Meet DNA Helicase
In previous articles (see here and here), I've been reviewing the molecular nano-machinery needed for the replication of DNA. Before DNA polymerase is able to synthesize the new complementary strands, it needs to be given access to the nucleotides of the single-stranded template DNA. The internal base pairing in the double helix must therefore be broken and the helix unwound. … [Read more...]
Replicating DNA with Extraordinary Fidelity: Meet DNA Polymerase
In a previous article, I gave a brief overview of the complex molecular mechanisms governing DNA replication. Now, I will focus specifically on the replication enzyme DNA polymerase. DNA polymerase is the enzyme responsible for synthesizing new strands of DNA, complementary to the sequence of the template strand. The unidirectional DNA polymerase progresses along the template … [Read more...]
DNA Replication: An Engineering Marvel
Recently I have been reviewing some literature on the elegant molecular mechanisms by which DNA is replicated. As an undergraduate biology student, I recall being struck by their sheer complexity, sophistication, and intrinsic beauty. As I read about such a carefully orchestrated process, involving so many specific enzymes and protein complexes, and its extraordinary accuracy, … [Read more...]
On The Dangers Of Fideism
On Saturday night, as I was home alone, the door bell rang. I opened the front door to greet the two young smartly-dressed gentlemen. They introduced themselves as missionaries from the church of Jesus Christ of Latter Day Saints (a.k.a. the Mormons). Interacting with Mormon missionaries is a rare treat for me. I'm currently abroad, working in Seattle, and Mormonism is far less … [Read more...]
What’s Wrong With The Zeitgeist Movie?
The Zeitgeist movie has been circulating on the internet since 2007. In the video its director, Peter Joseph, seeks to persuade viewers that the authors of the New Testament essentially plagiarized the concept of the virgin birth, December 25 as Christ’s birth date, the twelve disciples, the miracles, the crucifixion, and the resurrection from astrological sources and pagan … [Read more...]
The Nativity Defended
The Nativity and, in particular, the virgin birth has increasingly come under attack from liberal scholarship in recent years. Those committed to a naturalistic worldview dismiss the virgin birth of Jesus as fanciful. Some have even questioned whether Jesus was born in Bethlehem and whether Mary and Joseph’s venture to this town was prompted by the Roman census as recorded by … [Read more...]
