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 […]

Testing YEC Hyper-Evolution from Common Ancestors: Comparisons of mtDNA Genome Diversity in Mammals

Ken Ham’s Ark Encounter will vividly display what many young earth creationists believe the common ancestors of today’s species of animals may have looked like as they rode out a global flood 4350 years ago.   After disembarking from the ark, young earth creationists have proposed that these common ancestors experienced a burst of adaptive radiation into new  environments […]

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.

Is Ken Ham’s Rapid Post-Flood Diversification Really Evolution?

I ended my previous article, Ken Ham’s Darwinism, with the following observation: Ken Ham has fully embraced Post-Flood Rapid Evolution as a mechanism of creating the amazing variation we see today. As he slides further down the slippery slope into the rabbit hole of radical accelerated evolution he has now become, ironically, more accepting of naturalistic […]

A Horse is a Horse According to Answers in Genesis

A few weeks ago there was a report of an entire horse genome that was sequenced from a fragment of a horse preserved in permafrost sediments buried in the Yukon region in Alaska.  The fossil was estimated to be 500  thousand years or more old and thus this represented one the oldest DNA sequences yet […]

Equines of the Bible: Horse Series Part V

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 seen that evolutionary theory and most modern young earth creationists propose that the domestic horse, the donkey […]

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 […]

A Horse is a Horse, Unless of Course it Isn’t a Horse

Creationists are becoming more and more likely to view the origin of horse species and other large groups of similar species as the result as descent from a common ancestor albeit via mechanisms and at rates which may not be recognizable to evolutionary biologists. But where does does variation in a kind end and a new kind begin?

Consider the Moa: Extinct Flightless Birds of New Zealand

I am going to wrap up my miniseries on the ostrich (see Consider the Ostrich Part I, II and III) by examining some of the questions about origins that other flightless bird raise.   The ostrich is a flightless bird that has large wings though they are inadequate for flight because they lack the bone and […]

Consider the Ostrich: Adapted for the Present World? – Part III

Does Genesis require that ostriches were flight capable in the prelapsarian world?   If you have read parts I and II of this series you might think that I have overlooked one very important clue about the origin of ostriches: the Genesis creation account.   You could suggest that a logical argument can be made that the […]

Of Kinds and Common Ancestors: Comparing Mitochondrial Genomes of Mammals

A few days ago I shared some thoughts about the significance of genetic differences that are observed between humans and primates (How Similar is Similar, Part I). I said that it was important that genetic similarity numbers that are frequently used to make a case for genetic uniqueness need to be assessed in the context of […]
