Dude, unless you want to talk about something like new software applications which I do create and innovate I have to rely on what scientist publish. I am not in the position to excavated ancient fossils or make new discoveries. I defer to the experts of the field. They devote their life's work to it. For me it is just a passing interest, for them it is their profession. I would have to be pretty conceited to think that my knowledge in their field rivals their knowledge on the subject.
