"Although Darwin was able to persuade much of the world that a modern eye could be produced gradually from a much simpler structure, he did not even attempt to explain how the simple light sensitive spot that was his starting point actually worked"
About this Quote
The subtext is strategic: if the first step can’t be shown to work, the whole staircase looks suspect. That’s a signature intelligent-design gambit, especially in Behe’s orbit: shift the burden from “here’s a plausible pathway” to “explain every mechanistic detail at the origin point.” It’s also a way to make a historical figure stand in for an entire research program; Darwin’s 19th-century limits are used as a proxy for what evolutionary biology can or cannot explain now.
Context matters because Darwin actually did sketch incremental utility (light sensitivity to directional sensing), but Behe’s interest isn’t Darwin’s completeness. It’s the optics of incompleteness. By focusing on “how it actually worked,” he turns a question biology can answer in modern terms (photoreceptor chemistry, selective advantage of crude sensing) into a rhetorical wedge: if there’s any lingering uncertainty, the alternative story gets to walk in looking like rigor.
