Many of my Facebook and Twitter (X) friends, those that follow my blog (Naturalis Historia) and subscribe to my YouTube channel (Dr. Joel Duff) may not be aware that I am a PK (preacher’s kid). I know how difficult a pastor’s life can be. It’s an emotionally demanding job with high expectations, where everything said... Continue Reading →
Should professors at universities actively participate in generating and testing ideas, or should they content themselves with being teachers of established knowledge? Many higher educational institutions, including the one employing me, grapple with the ongoing challenge of balancing the encouragement of knowledge creation and the dissemination of existing knowledge. To phrase it differently, am I... Continue Reading →
Reflecting on common grace and intellectual exploration, I found the book "God and the Cosmos: Divine Activity in Space, Time and History" by Harry Lee Poe and Jimmy H. Davis to be a helpful read. The authors set the tone for their exploration by invoking a quote from the 16th century theologian John Calvin, a... Continue Reading →
Creation chronometry was a much debated topic in the late 1600s and early 1700s among Christians with virtually no opinion expressed being of the same kind that that could be described as a literalist view held today. I often wonder what would have happened had the Westminster Confession of Faith been written after this debate rather than before it given how the landscape of the discussion changed in the 40 years after the Assembly of the Westminster Divines met.
Billions of footprints are preserved in the rock record. While bones get all the attention, fossil footprints, a type of ichnofossils outnumber bones. How can we make sense of this observation? Surely, preserving a bone must be far more likely than preserving a footprint? I have written about how paleontologists use information from footprints and bones... Continue Reading →
We all recognize that LeBron James has a unique set of skills. He, you and I are all unique in some way if you think about the millions of variants in our genomes. But how was LeBron James made? How did he come to be the way he is? We find several biblical authors attributing... Continue Reading →
As an adult, you have experienced an astounding number of mutations during your lifetime – several quadrillion, to be specific. This number may seem unfathomable, but it's true. It's natural to wonder how you're still alive with such an immense number of mutations. How do we even know how many mutations have occurred in our... Continue Reading →
Ken Ham, the founder of Answers in Genesis USA, has no doubts about the proper classification of birds and dinosaurs. He believes that identifying birds a type of dinosaur should be rejected and labeled a compromised view, influenced by evolutionary theory. However, it would appear he has no problem considering whales and bats to be... Continue Reading →
Ken Ham has fired the first of what, apparently, will be many volleys against what he believes is one of the biggest threats to young-earth creationists: other young-earth creationists!! hanging them with the pejorative title of "young-earth evolutionists." Yes, Ken Ham is suggesting that one of the biggest danger to creationism--as defined by Answers in... Continue Reading →
Have you ever wondered about the origin of mythological creatures like dragons and griffins? Many ancient cultures believed in the reality of such creatures and depicted them in their art and stories. But where did these beliefs, these myths find their origin? Did they come straight from the imagination of social influencers of the day?... Continue Reading →
Most people know about Pixar's beloved film, WALL-E. Released in 2008 and directed by Andrew Stanton, this film has captured the hearts of many with its charming protagonist WALL-E or Waste Allocation Load-Lifter: Earth-Class. A few years ago I taught a Sunday school class on the topic of man's labor in the context of our... Continue Reading →
Natural Selection can be difficult to observe in natural populations. In the video linked below I examine a fascinating example of possible adaptation via natural selection of cliff swallows to the challenge of fast-moving vehicles in their environment. In the paper we will examine it was observed that over a period of 30 years, the... Continue Reading →
Mars once had a thicker atmosphere and liquid water on its surface. Nearly every month data from satellites and multiple ground-based systems provide new evidence confirming what was once speculation about the watery past of Mars. But how much water and how long ago did this water exist? A large amount of water still exists on Mars... Continue Reading →
The book “Traced: Human DNA's Big Surprise” by Dr. Jeanson of the Young-earth apologetics ministry, Answers in Genesis, claims to trace all human ancestry within the confines of a young-earth chronology. Ken Ham, founder of AiG and Dr. Jeanson's employer has claimed that "Dr. Jeanson has found the Rosetta Stone of human history" and extolled... Continue Reading →
How did the incredible species diversity today manifest itself from just a few individual animals preserved on Noah's Ark? How much speciation has happened? What are the mechanisms for young-earth speciation? Is there evidence that rapid speciation has occurred in just the past few thousand years? These are enduring questions that young-earth creationists have been... Continue Reading →
