Evolution is a vast subject and there are many books and websites that offer introductions as well as more advanced discussions to its many subtopics and related fields. Our purpose here is to provide answers to questions about evolution that frequently arise in connection with creationism. Some resources here are short, quick answers; others delve into college-level material. See also Kevin Padian's testimony in the Kitzmiller trial for a lively introduction to the science of paleontology.
