Ancient human mobility at the individual level is conventionally studied by the diverse application of suitable techniques (e.g. aDNA, radiogenic strontium isotopes, as well as oxygen and lead isotopes) to either hard and/or soft tissues. However, the limited preservation of coexisting hard and soft human tissues hampers the possibilities of investigating high-resolution diachronic mobility periods in the life of a single individual. Here, we present the results of a multidisciplinary study of an exceptionally well preserved circa 3.400-year old Danish Bronze Age female find, known as the Egtved Girl. We applied biomolecular, biochemical and geochemical analyses to reconstruct her mobility and diet. We demonstrate that she originated from a place outside present day Denmark (the island of Bornholm excluded), and that she travelled back and forth over large distances during the final months of her life, while consuming a terrestrial diet with intervals of reduced protein intake. We also provide evidence that all her garments were made of non-locally produced wool. Our study advocates the huge potential of combining biomolecular and biogeochemical provenance tracer analyses to hard and soft tissues of a single ancient individual for the reconstruction of high-resolution human mobility.

Scalp hair samples were studied from 10 term infants of normal weight for dates, 10 infants born very early of normal weight for dates and 10 infants born near term who were small-for-dates. The samples were examined morphologically and the diameters measured precisely using a scanning electron microscope. The control term-normal weight for dates infants had hairs which tapered gradually to the tip. Infants born very early had narrower hairs: these could be superimposed on the distal segments of the term infants hairs. Small-for-dates infants had hairs which where shorter and of narrower diameter for gestational age than the equivalent hair segments from normally grown infants, implying growth constraint from about 20 weeks of gestation. Amino acid analysis of the hairs from the three groups of infants showed no differences in concentration. These data suggest that no specific disturbance of any one or any groups of amino acids is the growth-limiting factor on the fetus as a whole in intra-uterine growth retardation.
