Abstract:
This paper presents our research regarding the influence of chemical composition and morphological aspects of soils on DNA degradation through fossilisation process. In order to achieve our goals, we collected 35 soil samples from different archaeological sites, from various depths and different archeologically periods of time-Neolithic, The Bronze Age, The First Iron Age, The Romano-Byzantine Age, VIII-X century. We performed pH determination, calcinations losses, SEM/EDS analysis of soil samples and we correlated our results with the DNA degradation index obtained from fossilized tooth samples collected from the same locations as soils.
The results obtained from this analysis represent a small part of our efforts in reaching out the main objectives: a) establishing the identification and differentiation criteria for forensic soils; b) establishing which types of soil better preserves, the human DNA from teeth and bones for further genetic analyses.
