Among the topics are inferring processes of Neolithic gene-culture co-evolution using genetic and archaeological data: the case of lactase persistence and dairying, evaluating the appearance and spread of domestic caprines in the southern Levant, early stock-keeping in Greece, the origin of stock-keeping and spread of animal exploitation strategies in the Early and Middle Neolithic of the North European Plain, and zoological data from Late Mesolithic and Neolithic sites in Switzerland about 6000-3500 BC, and earlier Neolithic subsistence in Britain and Ireland as seen through faunal remains and stable isotopes.
