Evolution proving its worth again

When advocates of Intelligent Design/Creationism try and tell you that evolution isn't a useful theory for the 'real world', remind them of examples such as this:

Two University of Canterbury biologists are part of a team whose evolutionary informed approach to conservation is aiding the recovery of New Zealand’s critically endangered parrot, the kakapo.

Dr Bruce Robertson and Associate Professor Neil Gemmell (Biological Sciences) are members of a research team that has just had a paper published in the Royal Society of London’s prestigious journal Biology Letters. The manuscript outlines how the team, led by Dr Robertson, used sex allocation theory to remedy a conservation dilemma.

It's also interesting on this point to counter by asking what use in terms of the 'real world' an 'Intelligent design' approach would actually have to basically anything.
