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 recently, I wondered when and how YECs had come to accept that new species can be generated by natural selection (The Origin of the YEC Hyper-speciation Model of Biological Diversity).
Since writing this last post I was made aware of a paper that I had overlooked that sheds much more light on the history of YEC views of the origin of species. That paper was written by Dr. Todd Wood and is titled: Species Variability and Creationism. Although I possess a fairly extensive library of older YEC published material I did not have or missed many interesting documents that Dr. Wood was able to track-down and inspect himself. This well-researched history of YEC thought on what constitutes a biblical “kind” helped me better understand the YEC view of how much speciation has occurred. I believe Dr. Wood makes a compelling argument that YEC leaders have accepted some degree of speciation for earlier than I had reported.
Dr. Wood works outside of the larger YEC organizations (eg. AiG, ICR and CMI) but has written some of the most articulate and scientifically literate articles that are found in the young earth creation literature. You might take that as a positive assessment of Dr. Wood or an indictment of the quality of most YEC literature. He is one of a very short list of creationists with authentic biology credentials who are actively thinking about what constitutes biblical kinds and the proposed mechanisms of rapid-speciation.
This week, Dr. Wood updated his followers on is current research on defining biblical kinds. In that update he shared a video he made earlier this year that explains his conception of how a “kind” might be defined and tested. I think this video is an excellent summary of the current state of the YEC model of the origins of species. I have linked to that video below for those that are interested in hearing Dr. Wood describe what a “kind” is and explain why he thinks that rapid speciation is not evolution. I would disagree with some of his conclusions but I commend him for taking a data-driven approach to addressing the questions he is interested in. The rest of the YEC community would be well-served, as I have noted in the past, to follow his research closely and model his approach to scientific inquiry.
