@Timmah. 'Design' is referring to the design of evolution, when an animal becomes more likely to survive than the rest of its species through mutation then it becomes more likely to survive, thus over time evolution can shape and change a creature to become different than what it was. Evolution can 'design' something.
Also DNA wouldnt have existed in the first creatures, something far more simple would have existed, DNA as with everything else in life, would have occured with evolution over time.
The first life on this planet we probably wouldnt even recognize as life, just a little bag of chemicals with the nifty ability to reproduce.
