Welcome to The Paleo-Environmental and Diet Laboratory (PaleoED)
Knowledge about past diets and human-environmental interactions is crucial for understanding the evolution of the human species and its behaviours, societies and cultures.
The Paleo-Environmental and Diet Laboratory provides a platform for the preparation of samples to characterize past diets, understand the evolution of organisms and their dynamics with human populations, and reconstruct past environmental changes.
In PaleoED we are able to prepare samples for geochemical analyses (e.g., stable carbon, nitrogen and oxygen isotopes in animal, human and sediment samples), molecular biological analysis (e.g., DNA extractions from plant tissues and preparation of genomic samples for next-generation-sequencing) and paleontological analysis (e.g., diatom, ostracode and molluscs analysis).
Molecular Biological Analysis
Molecular biological analysis of modern organisms can help us understand their evolution and dynamics with human populations over time. PaleoED provides a platform for the preparation of genomic samples for next-generation sequencing and to carry out DNA extraction (e.g., from plant tissues).
Stable Isotopes Analysis
Stable isotope analysis provides a means of characterizing past environments and diets, which is crucial for understanding the evolution of human behaviors and cultures. In PaleoED we sample and prepare animal and human bones collagen, dentine and enamel as well as sediment for carbon, nitrogen and oxygen stable isotope analysis and for biomarkers analysis.
Paleontological analysis
Paleontological analysis of macro- and microorganisms, combined with sedimentological and geochemical analysis, allow us to know past environmental changes and to better understand their role in the evolution of human species, societies, and cultures. PaleoED has the necessary material to prepare samples for micro-fossil analysis (e.g., diatom, foraminifera and ostracode).
