Origins and Extinctions: A Lesson from the Penguins of the Northern Hemisphere

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 […]

The Amazing Killdeer: Designed for Deception, a Good Creation, or Both?

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 […]

Pulling Teeth and Plucking Feathers – Ancient Birds and Young-Earth Creationists

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 […]

Consider the Ostrich—Comparing Theistic Models of Biological Origins

Some passages of scripture contain detailed natural history information about animals. The book of Job, in particular, records many physical and behavioral traits of animals. One such animal described in Job is the ostrich. The ostrich we know today is a strange bird. It is very large, its wings are not able to provide flight […]

If it Walks Like a Duck… Ken Ham Doubles Down on His Misunderstanding of Bird Fossils

Not long ago I wrote this post criticizing Ken Ham and his research team for their outright errors and misinformed understanding of ancient fossil birds. Subsequently, Ken Ham, with help from his research team, penned a second blog post entitled, “The Duck-Relative That’s Just a Duck.” In that article Ken Ham doesn’t correct his erroneous comparison of […]

The Universal Design Intuition—Undeniable or Unreliable? Reviewing ‘Undeniable’ by Douglas Axe 

Last year I was invited to write an essay reflection on Douglas Axe’s book Undeniable: How Biology Confirms Our Intuition that Life is Designed for the periodical Sapientia (Carl F. H. Henry Center for Theological Understanding an outreach of TEDS –Trinity Evangelical Divinity School).  That essay, Undeniably Limited: Designing a Box in Which to Find the […]

Young-Life Creationists—Who are the People that Believe they can Replace Darwin?

Young-earth creationists (YECs) are actively promoting a radical new model of the origin of the diversity of life on Earth. (1)  This speculative view borrows a number of elements found in any typical evolutionary biology textbook. For example, modern YECs claim that most and possibly all species alive today—except humans—are related to numerous other species […]

Penguin “Teeth” and “Modern” Birds: Ken Ham’s Misinformed Understanding of Fossil Birds

Errors repeated often enough take on the appearance of truth. This is what makes fake news so effective.   It can drown out informed opinion and accurate information.  At the root of many fake new stories are pieces of information that are either outright false but possibly surrounded with true statements or the facts they report […]

Walking Whales On Board Noah’s Ark: The Inevitable End-point of Creationists’ Post-Flood Hyper-Speciation Belief?

The diversity of life on earth today is staggering. Where did that diversity come from? How is that diversity maintained over time? How long did it take for that diversity to form? These are fundamental questions that biologists are interested in investigating. Conventional evidence-based biological theories ascribe biological diversity to the diversification of life over […]

Natural Selection Semantics: A Student Reacts to a Young-Earth Definition of Evolution

One method of examining a student’s grasp of a complex topic is to confront that student with an alternative point of view and ask them to critique it. If that student has a good working knowledge of the subject, they should be able to recognize the broad philosophical underpinnings of that alternative viewpoint and be able […]

Xenarthrans (Armadillos, Anteaters and Sloths): Another Biogeographic Puzzle for Young Earth Creationists

The Xenarthrans include the armadillos, anteaters and sloths.  What makes these animals different from other mammals? They all have a unique projections on their vertebral (back) bones; the ischium and sacrum bones of the hip are fused, unlike all other mammals; the males have internal testicles (no external scrotum) located near the bladder and they experience […]

Cacti Biogeography: A Prickly (Pear) Problem for Young Life Creationism

Young-earth creationists (YECs) routinely appeal to post-flood hyper-evolution to explain the diversification of pairs of ancestral animals into dozens and even hundreds of descendant species in the space a few hundred years following a global flood 4500 years before present.  For example, a pair of ancestral canines are said to have evolved in less than 1000 […]

NH Notes: Todd Wood on Creationism and the Origin of Species

If you have followed my blog for the past six months you know that I have been discussing the feasibility of the young-earth creationist’ (YEC) rapid-speciation model which proposes that hundreds of thousands of species of plants and animals have been formed by natural selection in just the past couple thousand years (YEC Hyper-evolution article archive).  More […]

The Origin of the YEC Hyper-Speciation Model of Biological Diversity

Young earth creationists (YECs) are the most vocal skeptics of evolutionary theory, however, they recognize organisms do change over time.  But how much? Everyone agrees that organisms have the capacity to adapt to their environments. This adaptive ability can lead to the formation of isolated genetic lineages we identify as species.  Evolutionary theory posits that continued […]

A Vivid Demonstration of Bacteria Adapting to Antibiotics via Mutations and Selection

The fact that bacteria are able to develop resistance to antibiotics has been a textbook example of evolutionary processes in action.  Mutations and natural selection – two primary agents of change – work together to sculpt new genetic combinations allowing individuals to exploit resources unavailable to bacteria unable to resist antibiotic chemicals in their environment.   Now you can […]
