The thing that is interesting with all facets of scientific research, nothing is actually proven. A hypothesis is proffered, if it cannot be disproven, then it is accepted as viable. That is until someone comes up with evidence of some description that may challenge the original acceptance, the research then continues.
I did my science degree through Murdoch University, and it basically involved reading what others had written (published authorities), then writing exactly the same information in another format to show that I had understood exactly what I had written. Of course giving references showing exactly where I had gleaned the information.
In the end a degree means not much more than the fact that someone can read and write and understand what they have read in the first instance. I intensely dislike the people that get a degree and then puit themselves forward ass being of superior intellect, that simply means they are foolish enough to believe what is not true, I have heaps to learn in the school of life, and enjoy learning it.
I would leave all research to teh buffons who need to have some kind of existence within the world of academia.
