This is interesting and promising. The AP reports that archeologists announced yesterday that they have been quietly excavating a Philistine cemetery since 2013. See here.
The team is now performing DNA, radiocarbon and other tests on bone samples uncovered at the cemetery, dating back to between the 11th and the 8th centuries B.C., to help resolve a debate about the Philistines’ geographical origins. The archaeologists have not announced any conclusions, saying they are taking advantage of recent advances in DNA testing to get the most accurate results.
“After decades of studying what Philistines left behind, we have finally come face to face with the people themselves,” said Daniel M. Master, professor of archaeology at Wheaton College and one of the leaders of the excavation. “With this discovery we are close to unlocking the secrets of their origins.”
