More subtleties. 1. Evolve - change by itself. Change applied to change. Man evolves from apes. The code was developed by me. However in time, it evolved into something that I was not able to imagine when I first created it. (I had personified the piece of code). 2. Develop - change experienced indivdually. The cell developed into a cancerous nature. Evolve - change experienced by a group. The species soon evolved into humanoids. 3. Develop - takes a much shorter time to be changed. He developed into a monster. Evolve - takes eons to be changed. Mammals were thought to be evolved from repitles. There are many more subtle meanings. Go check with a good dictionary such as the Unabridged Random House dictionary or the Oxford Dictionary.

To evolve is to change from one form to another, radically different form. The obvious example would be Darwinian evolution... However, you can apply this more generally. For example: "Even though he was a bad student way back when, but he's really evolved into an excellent professional," or, per random Google search, "...Social Media Will Evolve Into Social Business." To develop means rather to grow slowly, adding piece by piece or layer by layer to what's already there. You develop a skill, for instance... a basketball player is said to develop his jump shot, while somebody working abroad develops an accent. An infant in the womb is developing. Development need not always be positive however: somebody can develop a bad habit, while "recent developments" in the news often point to a turn for the worse. So, in summary, "to evolve" means to dramatically change into something entirely different, while "to develop" means to gradually change into something different.

Actually, they are the same word. "Evolve" is just fancier that "develop". However: evolve = focus on the actual change develop = focus on the end point of development The difference is clearer in the nouns: Evolution = the process of change development = the process of reaching a goal I hope that is clear.
