Dunkleosteus got me thinking about Occam's razor and "intelligent design."
Four-hundred million years ago, there was a fish with, instead of teeth, a "broad, razor-like rim of bone" -- an adaptation that could have given it an evolutionary advantage during the Late Devonian Period, when much of its prey was covered in bony armor.
So how does such an advantageous adaptation arise? Better question: How to you explain natural selection in a way that satisfies the doubters' doubts?
I'm not talking about the ideological creationists, who are unreachable. I mean our critically-thinking, spiritual friends and loved ones who are going to look at the fossil of a placoderm with, possibly, the strongest jaws in the history of life, perfectly adapted for munching equally-bony prey, and say,
Tell me that thing evolved totally by accident!
The thing is, positing a creator, any creator (a lot of folks believe in one, even if not in "YHWH"), seems more plausible to many folks i know. I mean, how could sequences of purely random coding errors in genetic replication taking place over eons produce anything more than goo?
So, how about it, skeptics? What's the sound-bitey answer for the layperson?
Defending the teaching of science as a matter of public policy demands making basic concepts of science cognizable by the law public.
So let's hear it!
