I tend to think its likely that animals do evolve into others, however, to play the devils advocate here, it seems that the case can be made that it seems rather natural for animals to evolve amongst their kind, like you could get a humming bird or an ostrich out of a chicken, a Chihuahua or a Great Dane out of a Labrador, but Im not sure if there are any cases that show the transition from one kind to another. Can you name one? Maybe there are, I havent seen any in all the books and videos and lectures I read about this but there could be, Im just saying.
These questions reveal a very typical, but fundamental misunderstanding of evolution as a whole.
I strongly suggest reading, as a good primer on the subject, The Greatest Show on Earth. I've found that this book is written at a beginner's level, yet explains all of the essential concepts really well:

I hope I don't come off as argumentative for the sake of argumentation, but I'd like to share my view that as good as Dawkins is in explaining things clearly and concisely, his books often lack in observations as well as explanations of their meaning, both quality and quantity wise, leaving the layman often in the impression that evolution is merely a collection of eloquent just-so-stories. Dawkins seems to recycle the same simple and sometimes irrelevant evidence, and his rhetorics of comparing creationists to holocaust deniers hurt his case more than anything. I add that I have not read "The Greatest Show On Earth" but the criticism I described is very similar to the criticism I have read of his latest.
A somewhat similar book that is a bit more harder to read for the layman but also more rewarding, is Ernst Mayr's "What Evolution Is" (2002). Mayr (1904-2005) was the last of the great old-school Indiana Jones biologists and I also suggest reading about some of his crazy adventures as an explorer in uncharted territories.
I also recommend reading two books that are easy to grasp but more confined in subject: "Endless Forms Most Beautiful" by Sean B. Carroll and "The Third Chimpanzee" by Jared Diamond (1991).
