But you may find this interesting even though it's a couple of hundred thousand years removed from your theory.

Francis Pryor is an archaeologist specialising in the European bronze age. He questions many accepted beliefs regarding agriculture, the 'Dark Ages' the Roman occupation of Britain, with an engaging and knowledgable humour. One of his hobbies is farming ancient sheep breeds - animals that were said not to respond to herding dogs.

It's worth reading the whole article; difficult to extract a pertinent few paragraphs.

"In fact I would go further than that. My foray into farming taught me that archaeologists not only can, but must look beyond the trench, the laboratory or the library. After all, who are we doing our work for? Cambridge taught me very well how to do archaeology, but they also instilled a misplaced sense of the exclusivity of the subject. Somehow it was too important to trivialise or to take lightly; we were privileged to be given access to its sacred groves. In retrospect, what made those attitudes so hypocritical was that our Professor, Glyn Daniel, had been elected BBC TV Personality of The Year a few years previously. The prevailing view throughout the Department was that archaeology was an orthodoxy: you didn’t invite outsiders into its church. You gave them your views, as I said in a recent blog post, ex cathedra – from the pulpit. And indeed, the tradition still continues in many presenter-led TV and radio programmes."
