Can you list some? I'd like to see them, at least the ones that aren't based on 'it's too complicated so it was designed.' That's not testable. It's scientific surrender.
For example if one took bacteria with the secretory apparatus that is the reducible complexity in the supposedly ‘irreducibly complex’ flagella, and selected them for mobility, would a flagella develop? At present the Dyscovery Institute is NOT pursuing this research.
