An online article soon to appear in the pages of the Journal of Archeological Science reports that about 8,000 years ago, some Siberian women had tapeworms, probably because of close contact with dogs whom the women cared for. Publicity for the new paper has revived attention to a controversial hypothesis about that closeness. As explained in a 2011 article in the Journal of Anthropological Archaeology from the same team,
We suggest that some animals with unique histories were known as distinct persons with ‘souls’ and because of this at death required mortuary rites similar to those of their human counterparts.
A detailed and highly technical exploration of the physical evidence for this idea, based on human and canid (wolf and dog) burials in the Lake Baikal region of Siberia, near present-day Irkutsk, appeared last year in the well-regarded open-access journal PLOS ONE.
So, is it true that people have been thinking that dogs have souls for that long? How confident can anybody living now really be about that, even knowledgeable experts, writing in well-known peer-reviewed journals with respectable impact factors?
