Dr. Laurie Reitsema's research has been highlighted in Nature Italy, a digital magazine that reports on scientific research, and issues of science policy, in Italy. The research has suggested that mercenaries played a more significant role in ancient Greek armies than previously thought. The study analyzed ancient DNA from soldiers buried in mass graves in the necropolis of Himera, a Greek colony in Sicily, revealing the presence of migrants from Eurasian regions. The findings highlight the importance of understanding the role of mercenaries in ancient Greek armies and provide evidence that they were essential for the victories of the Greek colonies in the first battle of Himera. The study demonstrates the significance of genetic analysis in uncovering important insights into the past, which can challenge traditional historical narratives and provide new perspectives on ancient history.
