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 […]

Ark Encounter Common Ancestors: The Increasing Inclusiveness of Biblical Kinds

Just how many animals where on Noah’s Ark according to 6-day creationists?  That answer has varied considerably over the past century.   With the completion of the Ark Encounter, the most visible attempt to show the feasibility of  preserving all land animal diversity from a global flood, more people are being exposed to a modern answer to […]
