"so at times, when I am expressing myself informally, and expressing enthusiasm, I admit that I might give the wrong impression."

I personally like your enthusiasm and I agree that most academics, out of fear to look stupid, to expose their ignorance, to strike a wrong chord with colleagues, etc. choose an overly cautious tone. (Most non-academics naively take this caution as a sign of knowledge which is the opposite from what it is.) However, I wish you did more research (the positive side of academic comportment) and stepping into the shoes of an archeologist, a comparative ethnologist or a linguist before coming up with rather novel ideas inspired by genetic phylogenies. Otherwise, I always find myself in an awkward position of being forced to choose between ignoring your posts altogether and "unblogging" them in the comments section. This may be too much to ask from a blog writer, though. Especially, since this writer is the only one who tries to take a holistic perspective on human prehistory.
