  Hi Aaron,
  
  Birds actually evolved from dinosaurs in the same family as the velociraptors!
  
  A really good example of an intermediate between dinosaurs and birds is a very famous example called Archaeopteryx which you can see here: http://en.wikipedia.org/wiki/Archaeopteryx
  
  All known types of birds evolved from dinosaurs!
