YEC Hyper-evolution Archive

The Ark Encounter, a young-earth creationist’ theme park, presents it visitors with exhibits with odd-looking creatures and explains that just 4350 years ago these were the common ancestors of  animal species we know today.  How and when did this transformation of “kinds” into thousands of species happen? At present, the consensus among young-earth creationists is that Noah’s Ark contained far fewer species of land animals than exist today even when extinct animals are considered. Therefore they have concluded that the vast majority of species have come into existence, or evolved if you prefer,  since departing Noah’s Ark.  This proposal has variously been referred to as the post-flood rapid speciation, post-flood hyper-evolution,  accelerated evolution, radically accelerated diversification or hyper-evolutionary creation.

Over the past two years I have published numerous articles on this blog which have examined many aspects of these young-earth views of the origins of modern biological diversity.   Topics discussed include:  Is there a viable mechanism? Has rapid-speciation been observed in the past or the present?  What is a biblical “kind?”  Is this neocreationist model really just evolution by another name?  Is there any biblical evidence for rapid evolution of species?

Below I provide links to some of those articles along with a short description.

Ken Ham’s Darwinism: On the Origin of Species by Means of Hyper-Evolution Following Noah’s Flood– Here I take a big look at how Ken Ham and AiG are changing the landscape of young-earth creationists approach to biological diversity.

Is Ken Ham’s Rapid Post-Flood Diversification Really Evolution?  I look even closer at the words of AiG and Ken Ham and ask, how what they are saying is different from standard evolutionary theory and how is it the same but cloaked in different terminology.

Dodging Darwin: How Ken Ham’s Ark Encounter is Slowly Embracing Evolution – Guest writer David MacMillan digs into how the Ark Encounter is going to present speciation within kinds and discovers that they are sliding down a slippery slope to accepting even more common descent than they already do.  What they are proposing has all the hallmarks of evolution of species over time but they try, unsuccessfully, to distance themselves from the implications of their own proposals.

Ark Encounter Common Ancestors: The Increasing Inclusiveness of Biblical Kinds – I take a quick look at the history of how young-earth creationists have been gradually broadening the definition of a “kind” over the past 50 years and ask how inclusive a kind may become in the future.

Walking Whales On Board Noah’s Ark: The Inevitable End-point of Creationists’ Post-Flood Hyper-Speciation Belief? -Combining the observation that no whales fossils exist in Flood rocks and the evidence that ancient whales had more land animal features some YECs are willing to consider that Noah had a walking land animal on the ark that then evolved into the present day whales.

Xenarthrans (Armadillos, Anteaters and Sloths): Another Biogeographic Puzzle for Young Earth Creationists – Sloths, anteaters and armadillos are only known from the New World. How did they get there from the Ark and how is this a challenge for the speciation model of YECs?

Cacti Biogeography: A Prickly (Pear) Problem for Young Life Creationism – YECs talk about animals quickly speciating after the Flood but what about plants?  Plants present additional problems to the YEC flood narrative.

The Origin of the YEC Hyper-Speciation Model of Biological Diversity –  A quote from a creationists publicatoin from 1945 suggests that their hyper-speciation beliefs go back at least that far.  However, YEC followers still generally believe that speciation is evolution.

Is Natural Selection the Same Thing as Evolution: Assessing Dr. Purdom’s Confusing Answer – Dr. Purdom attempts to explain how speciation by natural selection is not evolution with some very unorthodox interpretations.

The Great Genetic Bottleneck that Contradicts Ken Ham’s Radical Accelerated Diversification or Post-Flood Hyper-Evolution – One huge problem for Dr. Jeanson’s hypothesis that the original kinds were endowed with massive variation (heterozygosity) in the original creation is the problem of Noah’s flood which should have been a massive genetic bottleneck and thus destroying the variation needed for post-flood hyper-evolution to even have a chance of working.

Ken Ham’s Biblical Evolution: I have a Book that Says Otherwise – In the Ken Ham/Bill Nye debate, Ken Ham said he had a book that proved his case regarding the age of the Earth. However that same book provides ample evidence that his hyper-speciation model is without merit.

A Creation Museum Speaker Asks:  Do Animals Evolve? A  Critique – AiG speaker Bryan Osborn explains the AiG view of what the limits are to animal evolution.   I review his general thesis by walking through some of the slides from his presentation.

Invoking Super-speed Evolution: The YEC Post-Flood Big-Bang of Bird Speciation  – How do YECs fit 10,300 bird species onto the Ark? They squeeze them into just 200 “kinds” which then rapidly evolved into the amazing diversity of birds we have today.

Ruminating of the Meaning of Noahic Kinds:  Are Ruminants Derived from a Common Ancestor?  – Are giraffes, gazelles, antelope and pronghorn all derived from a common ancestor?  Creation scientists aren’t sure but some have suggested it might be possible.  So just how inclusive can a kind be?  The definition seems to expand every time a creationist writes about it.

Testing YEC Hyper-Evolution from Common Ancestors: Comparisons of mtDNA Genome Diversity in Mammals –  Here I provide to compare how different some species of mammals are using mtDNA sequences.

Gyptodonts, Armadillos and Ken Ham’s Hyper-Speciation Model – Here I take a look at one group of strange animals from the western Hemisphere and ask if the hyper-speciation model makes any sense for this group.

Did Modern Animals Evolve from the Inhabitants of the Ark?  –  This is a short article that I wrote for after visiting the Ark Encounter shortly after it opened.

In addition to these articles I would also highly recommend a recent article by David MacMillan that examines Dr. Jeanson’s attempts to provide a genetic explanation for rapid-speciation.  That article, Creationists evolve “new” arguments to explain genetic diversity, was published at Panda’s Thumb



  1. What I always find interesting is how YEC’s intentionally ignore the following conundrum: If we consider for a moment Ken Ham’s fantastical evolutionary fairy tale to be true, and if Ken Ham considers domesticated dogs, wolves and foxes to be of the same kind, and all housecats, wild cats and tigers and lions to be of the same kind sharing a common ancestor on board of Noah’s ark, then surely Noah and his family should’ve been something as primitive as a Homo Habilis or Australopithicus?

    Ham’s hyper-evolution and his flexible definition of kinds surely must result in some primitive species of the homo genus building that precious Ark of his.

    These articles should make for a very interesting read!



  1. […] develop so quickly from the “1,000 kinds” that came off of Noah’s ark a mere 4,000 years ago? Joel Duff writes about the claims of hyper-evolution made by YECists, who claim there was an explosion of genetic variation immediately after the flood, but then soon […]


  2. […] Possibility of Post-Flood Hyperspeciation (Joel Duff has analyzed this concept here.) […]
