Yes, I know that my first post on this topic was about the occupants of Durrington Walls eating Durritos, but, levity aside, I think that the ancient occupants of these islands understanding of their botany and its practical application in the form of medicinal and culinary practice - the two are interlinked - is an underappreciated area of study. I suggested Dr Alice as she has a grounding in human biology as well as archaeology and is 'good tv', imho.
