Paleolithic and neolithic lineages in the European mitochondrial gene pool.
It follows that the major extant lineages throughout Europe predate the Neolithic expansion and that the spread of agriculture was a substantially indigenous development accompanied by only a relatively minor component of contemporary Middle Eastern agriculturalists. Expand
Nitrogen isotopes and the trophic level of humans in archaeology
A set of models is developed which, with small changes made in assumptions, can produce substantially lower estimates of the dietary animal protein fraction for given δ 15 N values. Expand
Detection of breastfeeding and weaning in modern human infants with carbon and nitrogen stable isotope ratios.
The finding of a carbon trophic level effect in breastfeeding infants suggests that (13)C-enrichments of approximately 1 per thousand in archaeological populations are not necessarily the result of the consumption of C(4)-based weaning foods such as maize or millet. Expand
Improvements to the Pretreatment of Bone at Oxford
Bone is one of the most widely used materials for dating archaeological activity. It is also relatively difficult to pretreat effectively and new methods are an area of active research. The purposeExpand
Bone diagenesis: an overview of processes
This overview is a summary of the state of understanding of processes and states in bone diagenesis, as seen from a chemical perspective. It deals with the significance and usefulness of theExpand
Nitrogen balance and δ15N: why you're not what you eat during pregnancy
Carbon (13C/12C) and nitrogen (15N/14N) stable isotope ratios were longitudinally measured in human hair that reflected the period from pre-conception to delivery in 10 pregnant women. There was noExpand
Investigations into the effect of diet on modern human hair isotopic values.
It is demonstrated that the magnitude of the nitrogen isotopic values of hair keratin reflects the proportion of animal protein consumed in the diet: omnivores and ovo-lacto-vegetarians have higher delta15N than vegans, providing the first independent support for a long-held theory that, for individuals within a single population, a diet high in meat equates to elevated nitrogen isotopy values in the body relative to others eating less animal protein.

New evidence of Lateglacial cereal cultivation at Abu Hureyra on the Euphrates
New evidence from the site of Abu Hureyra suggests that systematic cultivation of cereals in fact started well before the end of the Pleistocene by at least 13000 years ago, and that rye was among the first crops. Expand
Fossil dogs and wolves from Palaeolithic sites in Belgium, the Ukraine and Russia: osteometry, ancient DNA and stable isotopes
Using multivariate techniques, several skulls of fossil large canids from sites in Belgium, Ukraine and Russia were examined to look for possible evidence of the presence of Palaeolithic dogs.Expand
