What kind of information or items, did he use to support his theory
Evidence used to support evolutionary theory includes the fossil record showing the progression of species over time, comparative anatomy and genetics showing shared traits among different species, and the observation of natural selection acting on populations leading to adaptation and speciation.

If you browse around this category, you will find several similar questions with replies that answer your query. ==================================== Real scientists do not "gather evidence in support of" any theory. The technical term for that kind of thing is "cherry-picking". Real scientists build a theory to explain the evidence that they have already gathered, and then test the theory to see whether it holds water. The easiest, fastest way to make sure that you are regarded as a wingnut by real scientists is to adopt or invent a theory, and then spend your time trying to prove it.
