One of the best things about following the antics of creationists is that it gives you a better appreciation of the creative power of the human mind…which isn’t anywhere near as powerful as reality. Here’s another example of creationist rationalization that doesn’t hold up well under even casual inspection.
With the notable exception of the American Bison most mammals have two separate pleural or lung cavities. As we all know, one side of our chest can be penetrated collapsing that lung, but the other side remains intact and the remaining lung can support life. The bison has what is called an incomplete mediastinum, that is there is but one pleural cavity containing both lungs. Thus the problem for the Native bow hunter with or without a horse is solved. An arrow must only penetrate the chest at any point and both lungs collapse. The fatally wounded animal would only continue a few yards providing unlimited food, clothing and tools. Before the availability of horses bison could be shot by stealth from a blind or other hiding place. One problem is solved yet another serious comes to mind…a problem seldom mentioned, yet demanding an answer.
The problem is for the evolutionist. Other than providing food for hungry people, of what selective advantage is an incompletely divided mediastinum? From an evolutionary sense this makes absolutely no sense. Indeed conventional wisdom would argue for its elimination from the gene pool. Yet it did remain and fed a continent of Native American for centuries. It must indeed require faith and dedication to remain an evolutionist. I am glad I know the Creator of Bison and Native Americans. You can know Him too.
So, wait…God hates bison? Doesn’t this create a logical problem for the creationist, in that God has made the primary large game animal targeted by the Native Americans exceptionally fragile?
And let’s question that assumption: bison aren’t particularly weak, and there’s no reason to assume that selection would work to promote the evolution of dual compartments in the chest cavity — that’s almost certainly an embryological accident in the first place. How many wild animals are running around with only one lung? Not many. If you’re attacked in such a way that your chest cavity is perforated, the only difference between a separated and unseparated mediastinum is whether your death will be slow or quick.
And of course, I thought the Hebrews were the chosen people. How come God didn’t give the Middle East a population of big game animals they could knock over with a good sharp poke?
Canadian Cynic has a nice sharp rebuttal: “…if God had really cared about native Americans, he might have given them immunity to smallpox.”
