but cooking pots remain', suggesting that the foreign Aegean elements in the Philistine population may have been a minority. Geographic evolution Material culture evidence, primarily pottery styles, indicates that the Philistines originally settled in a few sites in the south, such as Ashkelon, Ashdod and Ekron. It was not until several decades later, about 1150 BC, that they expanded into surrounding areas such as the Yarkon region to the north (the area of modern Jaffa, where there were Philistine farmsteads at Tel Gerisa and Aphek, and a larger settlement at Tel Qasile). Most scholars, therefore, believe that the settlement of the Philistines took place in two stages. In the first, dated to the reign of Ramesses III, they were limited to the coastal plain, the region of the Five Cities; in the second, dated to the collapse of Egyptian hegemony in southern Canaan, their influence spread inland beyond the coast. During the 10th to 7th centuries BC, the distinctiveness of the material culture appears to have been absorbed with that of surrounding peoples. Burial practices The Leon Levy Expedition, consisting of archaeologists from Harvard University, Boston College, Wheaton College in Illinois and Troy University in Alabama, conducted a 30-year investigation of the burial practices of the Philistines, by excavating a Philistine cemetery containing more than 150 burials dating from the 11th to 8th century BCE Tel Ashkelon. In July 2016, the expedition finally announced the results of their excavation. Archaeological evidence, provided by architecture, burial arrangements, ceramics, and pottery fragments inscribed with non-Semitic writing, indicates that the Philistines were not native to Canaan. Most of the 150 dead were buried in oval-shaped graves, some were interred in ashlar chamber tombs, while there were 4 who were cremated. These burial arrangements were very common to the Aegean cultures, but not to the one indigenous to Canaan. Lawrence Stager of Harvard University believes that Philistines came to Canaan by ships before the Battle of the Delta circa 1175 BCE. DNA was extracted from the skeletons for archaeogenetic population analysis. The Leon Levy Expedition, which has been going on since 1985, helped break down some of the previous assumptions that the Philistines were uncultured people by having evidence of perfume near the bodies in order for the deceased to smell it in the afterlife. Genetic evidence A study carried out on skeletons at Ashkelon in 2019 by an interdisciplinary team of scholars from
