DESCRIPTION:This presentation explores ancient genomic data from the Irish
  Mesolithic and Neolithic periods\, including individuals sampled from all
  the major megalithic funerary traditions. We find evidence for a heredita
 ry elite in Irish passage tomb societies. This includes a web of biologica
 l kinship connections across large temporal and spatial distances on the i
 sland\, as well as a case of first degree incest associated with the right
 hand recess of the main mound at Newgrange. We also find incidences of div
 ersity among the individuals interred within megalithic tombs. This includ
 es the remains of an infant with Down syndrome at Poulnabrone portal tomb 
 and an individual with ancestry derived from the Irish Mesolithic populati
 on at Parknabinnia court tomb. Genomic data from two Irish Mesolithic indi
 viduals points to an island isolation\, which ended with a seemingly rapid
  maritime colonisation of the island during the Early Neolithic.
