Biologist Kenneth Miller destroys intelligent design by pointing out how in living creatures the function of a structure can change over time. And if the function is mutable nothing can ever be irreducibly complex. Example: The stinger in honey bees is a modified egg depositor (ovipositor), which is why male bees cannot sting. The natural world is filled with tinkering and re-tinkering, not design. But, of course, ID supporters just ignore the lack of evidence for irreducible complexity and they keep on vomiting up pseudoscientific garbage.
