Irreducibly Awesome

  As part of its Expelled Exposed project, the National Center for Science Education tackles that tired creationist argument, irreducible complexity. If you're not familiar with this line of reasoning, it basically goes like this:

"I can't imagine how [COMPLEX ANATOMICAL STRUCTURE] could possibly have evolved from simpler structures, without any deliberate guidance. Therefore, relying only on my own ignorance as evidence, I conclude that [COMPLEX ANATOMICAL STRUCTURE] must have been conjured up fully formed by a benevolent sky-grandpa."

  Luckily for the poor, misguided creationist, there are plenty of scientists who can imagine, and describe in great detail, the intermediate stages and slow development that led to the current version of [COMPLEX ANATOMICAL STRUCTURE]. In the video below, they demystify the development of perhaps the favorite target of the irreducible complexity argument, the eye. Enjoy.
