'Evolve' doesn't quite work here, either. 'Develop' might be a better word. And to answer your question, no, you don't need the 'to'. Most verbs have strict rules as to what construction follows them, but 'help' is an exception. You can use either [help+to+infinitive] or just [help+infinitive]. The two forms are equally correct, equally common, and have exactly the same meaning. I hope that's helped solve your problem. I hope that's helped to solve your problem. Take your pick!
