This is a cop-out used by theists when they are backed into a corner and realise they can no longer deny the fact that evolution takes place on a daily, global, basis. Little consideration is given to the gods of other religions. Fundies have a hard time with evolution. However, Fundies then attempt to make the two sound completely unrelated. Micro-evolution is change within a species, eg.
Speciation happens almost on a daily basis.
More details here. Evolution is most simply defined as a change in the frequency of genes over time. Obviously, given more time more changes can occur, but the mechanisms behind those changes are exactly the same. Basically, if you have two or more explanations for a particular phenomenon, it makes sense to go with the simplest one. Ilya Prigogine won the Nobel prize in 1977 for his work on the thermodynamics of nonequilibrium systems.
