"Please name one scientific theory that has been proposed as an alternative to evolution."

So called "Design science". The idea that biological structures are often so irreducibly complex that they could not have arisen gradually through the process of mutation and natural selection.

(To which you will undoubtedly reply--it isn't a scientific alternative, proving my point.)

So called "Design science"

Ah. Please describe how we can set up an experiment to disprove said theory (which is a requirement).

So called "Design science". The idea that biological structures are often so irreducibly complex that they could not have arisen gradually through the process of mutation and natural selection.

What does this theory predict, how can those predictions be tested and what hypothetical observation would falsify the theory?
