Yes they were. I though of writing a snarky response, but I gave you the benefit of the doubt that your post was the result of not knowing anything about evolution and not trolling. If you really are interested in knowing the answers to your questions then you need to study evolutionary biology - it really is a very interesting topic :)
Edit. If you want to know more then any of Richard Dawkins biology books are really good. The Blind Watchmaker would be my suggestion of where to start.
Yes, but it can be really hard trying to make sense out of all the information without having the assumed knowledge. I would really recommend starting with a good book that assumes very little.
