Preadaptation implies organs evolved before they were needed (Talk.Origins)
Evolutionists invoke preadaptation as an explanation for how some features arose. Preadaptation says that organs and other features evolved before they were needed. But an unneeded feature would never be selected, so the whole concept contradicts the theory of evolution.
This is not a Creationist claim.
Note that no source is given for this claim that is because there is none.
