Invoking Super-Speed Evolution: The YEC Post-Flood Big Bang of Bird Speciation

The diversity of birds on earth is remarkable. There are more than twice as many bird species alive today as there are mammal species.  A challenge for literal-day creationists is explaining how such diversity was either preserved during a global catastrophe not more than 4500 years ago or was formed after that event. Did Noah’s Ark hold […]

Is Natural Selection the Same Thing as Evolution? Assessing Dr. Purdom’s Confusing Answer

The ministry of Ken Ham’s Answers in Genesis exists, in part, to provide Christians with responses to what they believe are anti-biblical beliefs about the age of the earth and the origin of biological diversity.  To provide these answers, AiG has assembled a small group of geologists and biologists.  These employees provide answers to questions that […]

Are Ruminants Derived from a Common Ancestor? Ruminating on the Meaning of Noahic “Kinds”

What do giraffes, cows, sheep, antelope, and deer have in common?  Foremost, they all share a specialized digestive system that includes a four-chambered stomach that allows them to obtain nutrients and energy from vegetation that is inaccessible to most mammals.  This ability and other shared morphological traits are used by scientists to classify all of […]

Dodging Darwin: How Ken Ham’s Ark Encounter is Slowly Embracing Evolution

As the strict young-earth creationists at Answers in Genesis work to complete their Ark Encounter “theme park,” they have expended an impressive amount of energy organizing the millions of species of land animals alive today into a handful of small groups they call “baramins.” Creationists insist that while adaptation or speciation within a particular “baramin” is observable (and, indeed, necessary in order to account for the present observed diversity of life), there is never any overlap between separate kinds. Unfortunately for the young-earth model, the push to minimize the number of animals riding on the Ark has exposed a major problem with this view.

The Diversity of Life: An Introductory Lecture

Have you even wondered what students at a public university are taught in a general education biology class about the diversity of life?  I can’t promise that what I am going to share is typical but it is what over 100 students heard yesterday in my class.  Below I share a link to a recording (voice/PPT […]

Origin of a New Parasite? Tasmanian Devil Transmissible Tumors

Can cancer become an infectious disease?  Usually with think of cancer as limited to the individual in whom the cancer formed.  But what if cancerous cells could infect other individuals. Here is a link to a story on the sad case of what happens when cancer “learns” to infect more than one individual:  BBC News […]

We’re Going on a Fossil Hunt to Find a Herpes Virus

There is a very recent form of fossil hunting that I have gotten to partake in to some small extent, and I can do it while sitting in front of a computer screen! With some computer skills and some knowledge of animal genomes it isn’t difficult to join this hunt for fossils inside the genome of living organisms.

Invoking Super-Speed Evolution: How to Squeeze 10,000+ Bird Species onto Noah’s Ark

There are about 10,000 species of birds alive today.  Almost 200 additional species have gone extinct since the year 1500 and there are innumerable fossil species of birds in the geological column. One of the persistent challenges for modern young earth creationists is how to fit the diversity of life on the Noah’s ark.  Answers […]

When is a Horse a Horse? The Species Definition Problem

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 how do we know when we have stretched a horse beyond being a horse?   Although I talked about the definition of horses in the context of creationist’ theory, I […]

What is a Species? Tasmanian Devil Transmissible Tumors
