    “…We demonstrate that previously unexploited local plants were incorporated into the Philistine milieu, and new species were introduced–from Europe, the Aegean, Egypt and Mesopotamia –resulting in the earliest locally cultivated sycamore, cumin, coriander, bay tree and opium poppy. This research has highlighted the impact of past cultures on the formation of floral ecosystems and their long-term effects on contemporary local biological diversity.…”
