EAA 2023 keynote: Tales from a small island: archaeological genomics on the Atlantic edge

This shared talk focuses on our work on the ancient genomics of Ireland and examines three features of past societies: migration, kinship and survival. These leave signatures on the genome, which can tell the story of a single individual or entire island. First, we characterize the ebb and flow of migration to Ireland: are perceived shifts in ancestry the result of gradual transitions or did the island experience episodes of population replacement more akin to cliff edges? If the latter can we appreciate the complexity in a sharp transition? With denser sampling and sensitive haplotype-based methods, we can detect local-migrant interactions and patterns of individual mobility. Second, we leverage haplotypes to identify near and distant biological relatives. Kinship practices and group identities can shape patterns of genetic relatedness and inbreeding within and between communities, which we explore through several case studies. Third, the health of populations and individuals is shaped by short and long-term interactions between genes and the environment. Ancient genomes allow us to chart the trajectories of important mutations and reveal the past selective pressures that have helped mould the population of the island today.
