Crockford, S. J., ed. (2000). Dogs through time: an archaeological perspective. Oxford: Archaeopress.

the author examines the evolution of the dog from an evolutionary perspective, and presents a model for domestication that does not require humans to have played an active role in the initial stage of the generation of primitive dogs

the paper examines the question of skeletal uniformity in prehistoric British dogs; in particular it reassesses the trends visible in the later prehistoric, particularly the later Iron Age populations. A number of questions are raised about the apparent uniformity of dogs prior to the Romano-British period, and the paper also discusses whether archaeologists are optimising the data available to us in British archaeological assemblages

preliminary coat length and hair diameter data are presented for ten breeds of dog. In general larger breeds had greater hair diameters than smaller breeds, and males had greater hair diameters than females. The author suggests that coat variation in archaeological remains could throw light on dog breed origins. Most breeds had skewed hair diameter distribution in which the bulk of hairs were fine (the undercoat) with fewer coarser fibres (the outer hair). In some animals there was a seasonal narrowing of the hair in autumn, indicating a seasonal cycle of growth

some of the issues associated with dog evolution raised in the volume are examined from a broader perspective; in particular, the potential significance of certain morphological similarities among regional populations of prehistoric dogs is discussed, along with the development of distinct breeds. In addition the author addresses the situation resulting from the early prehistoric expansion of the dog into territories occupied by its ancestral species, the grey wolf
