The development of human societies has involved a shift in the relationship between humans and animals. This 4-year PhD project aims to study how the synchronous evolution of humans and animals has affected their genomes throughout history and how this has resulted in current populations. For this, human and animal remains from different sites in modern Poland that span a vast time period, from the Neolithic to the Early Middle Ages, will be analysed. The animal remains will focus on domesticated species such as dogs, sheep and goats; however, wild animals like deer will be added to the study to obtain a more comprehensive picture of the changing environment. This application seeks the necessary core hours to perform bioinformatics analysis on biological data from ancient samples.
