How can a population of organisms reproduce and over some period of time diversify into hundreds of species each of which has its own menagerie of unique characteristics? This is a fundamental biological question for which many different mechanisms have been proposed as solutions over the past 200 years. Young-earth apologists say they have replaced...

The talk of the world is coronavirus-so many questions. How did it come to infect humans? How should we go about controlling its spread? Will the virus mutate and become more infectious or deadly? Are there any effective treatments? There is no shortage of speculation and ongoing research hoping to provide answers to these questions. ... Continue Reading →
How did the earth become populated by billions of species of living things? Conventional evolutionary biology provides an explanatory framework to answer that question. Intelligent Design advocates provide another as do Progressive Creationists (Old Earth Creationists). But a large segment of the population looks to creation scientists (Young-earth creationists—YECs) to answer the question. How do... Continue Reading →
The Ark Encounter theme park in Kentucky is filled with signs and displays that promote young-earth interpretations of geology, astronomy, biology, archaeology and theology. I have critiqued many of these interpretations before (e.g. My Trip to the Ark Encounter and Depicting a Real Flood with Unrealistic Images). Today, I want to talk about one sign....

I recently attended the annual meeting of the American Scientific Affiliation held at Wheaton College. About 300 professional scientists who are professing Christians had gathered to discuss a variety of topics related to science and faith. Monday morning I delivered my presentation titled: “Young Earth evolutionists? Adaptation of young-earth creationist models, and implication for the... Continue Reading →
How many animals did Noah preserve on the Ark? I often see critics of young-earth creationists (YECs) challenge Noah’s Ark with the question, how could Noah have fit all two million species on the ark? When I see this challenge posed on Facebook or Twitter it is invariably coming from an individual that knows very... Continue Reading →
Have you ever wanted to get inside the head of a young-earth creationist or an evolutionary creationist and hear what they are thinking about each other? What about their fears and concerns, what makes them hold on so strongly to what they believe, what do they think about conflict and can they find any common... Continue Reading →
Thus far in this series about horses we have we have explored some of the interpretations of the fossil record of horses and demonstrated the difficulty of defining the boundaries of species of modern horses. We have observed that evolutionary theory and most modern young earth creationists propose that the domestic horse, the donkey... Continue Reading →
In our last installment of this series, When is a Horse a Horse? we recognized that the living species of equines (horses, zebras, donkeys etc..) represent groups of genetically divergent individuals that naturally do not interbreed on a regular basis. Each of these lineages of equines is behaving as a species as defined by the biological species concept. This raises the... Continue Reading →
In my introduction to the origin of horses I suggested that a horse is a horse of course, unless of course it isn’t a horse. But that begs the question, how do we know what the boundaries are of what constitutes a horse? Although I suggested that young-earth creationists (YECs) have diverse views of what...

One year ago witnessed the publication of what Ken Ham and others at the young-earth ministry, Answer in Genesis (AiG), clearly hoped would provide a comprehensive, alternative approach to explaining the origin of species and, more generally, biological diversity within a 6000-year time-frame. As the bold title, “Replacing Darwin: The New Origin of Species,” proclaims,... Continue Reading →
Young life creationists, or baraminologists as they prefer to be called, have experienced a paradigm shift over the past three decades. During that time they have increasingly embracing a model of common ancestry and accelerated evolution as they seek to explain the origins of the vast diversity of life on Earth. This accelerated or hyper-evolution... Continue Reading →
Question: What kind of bird is flightless, waddles standing upright on the ground, is an excellent swimmer, breeds in colonies on rocky shores, lives on a diet of fish and has a white belly and black back, and most importantly is not a penguin? The answer: The extinct great auk. You can think of the... Continue Reading →
Birds, like all organisms, employ many strategies to ensure that their offspring will survive, thereby allowing the continued existence of the species. Some birds produce elaborate nests high in trees, on rocky ledges or even inside caves to protect them from ground-dwelling predators. Others, like penguins and many shorebirds, nest together, overwhelming predators by sheer... Continue Reading →
A few weeks ago I criticized Ken Ham and several of his Answers in Genesis' colleagues for stating that some living birds have teeth like those of fossil birds. I pointed out that none of the 10,000 living bird species produce true teeth. However, there were some birds that lived alongside dinosaurs during the Cretaceous... Continue Reading →
