"There is much misunderstanding of this term, and people often pack a lot of differing concepts under it. Consider this rant by a creationist in The American Spectator: there are "six types of evolution" according to him. They are cosmic evolution, chemical evolution, stellar evolution, organic (or organice [sic]) evolution, macroevolution and microevolution. Apart from being deeply ignorant about all the topics he classifies, some of this is just ridiculous."
