Change of research topic.

The topic that I chose before; I could not find any information, so I have changed it. I have chosen a topic that is related to Art, It is; Is readymades considered art. I chose this topic because, I am already familiar with the subject, also it is a topic that has, and will continue to be an issue.
This particular subject in art has yet been explored extensively, or even argued that much. What I know of this subject is readymade art is taking an everyday object and slapping there name on it and calling it art. This type of art comes from the Dada movement in the 1920's.
The part I would like to gain insight on a little more is how a lack of creativity and hands on work can possible be considered art. Another aspect of the subject I would like to know if someone did not create a piece of work with there bare hands isn't it considered a copyright law or equivalent to plagiarism.
