Arise Quote by Michael Behe
“Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.”
About This Quote
Complex biological structures that appear irreducibly complex must arise as whole units for natural selection to act, implying a need for integrated function from the start.
In simple terms: Complex systems need to form fully before evolution can shape them.
Key Takeaway
Consider whole-system origins in evolutionary explanations.
