Michael Ruse wonders why evolution is still being debated. Our readers weigh in:

clearmind: "The question is, if everything we have and everything we are--from our miraculously finely-tuned and well-ordered physical structures, to our emotional outlooks, our religions, our cultures--are all determined by their having survival value, then why do we seek so much beyond mere survival?"

rchill: "I still can spend hours looking through my microscope. But, the wonder of life is still not 'evidence' of a designer. Science requires a natural explanation, requires its practitioners to be 'doubting Thomases', whereas faith is belief beyond proof; its concern and focus is the spiritual world, not natural world."

• Poverty, Reconsidered: Ever since economists started trying to keep tabs on poverty, they've done so by measuring income. But what if that's the wrong way of going about things?

• The Mix Tapes of Osama bin Laden: Neither CNN nor FBI could find much use for Osama bin Laden's personal collection of audiocassettes, but Flagg Miller is listening, and he says there's much to be learned.
