Nicolas states in the introductory paragraph:
Here is my dissertation on heterochronic theories of human brain evolution. Hope you find it useful
He discusses some of the main contributors to the field comparing, contrasting and summing up the leading theories. I don't have the expertise to judge the content but it makes sense to me in my ignorance. He seems to have correctly cited his sources. Of course it could be plagiarised or made up whole cloth for all I know. The net makes all that easy to do. If the paper was archived on the internet he could have posted a link to it. But taking it at face value it seems a very well researched over view of issues in the field it claims to be addressing. I was frankly wowed by it.
The paper is densely annotated but that may be the necessary style when presenting scientific papers. I only get a general understanding from it. Those better educated in science might have more to say on this.
It looks to me he gave a complete with citation answer to the OP. I can't find fault with that. It's rare to get such a well laid out answer on a topic. It might have been too much detail but hey, that's why we learn to skim!
