According to an article in today's New York Times, "in addition to confirming elements of a major transition in evolution, the fossils were a powerful rebuttal to religious creationists, who have long argued that the absence of such transitional creatures are a serious weakness in Darwin's theory."
D'oh!
So what are these "creationists" and other "know-nothings" going to argue next, now that their main counter-argument to Darwin - that "not a single fossil with part fins, part feet has been found" - has been utterly demolished? Hopefully, their ideas will follow yet another powerful aspect of evolution theory - extinction. Just like the "fishapod" itself. Ha.
Fun facts to spout back at believers in Biblical inerrancy: there are two contradictory stories of the creation in Genesis. http://www.skepticsannotatedbible.com/contra/accounts.html
