Phylogenetic Perspectives and Ethnobotanical Insights on Wild Edible Plants of the Mediterranean, Middle East, and North Africa

This study investigates the phylogenetic and geographical distribution of wild food plants (WFPs) across 30 Mediterranean and North African (MENA) regions, focusing on the intersection of evolutionary lineage, ecological adaptation, and cultural utilization. A phylogenetic analysis of 111 genera of WFPs used in traditional diets reveals clusters reflecting shared ancestry, functional adaptations, and ecological resilience. Key regions such as Lebanon and Ikaria stand out as potential centers for the diversity of wild food plant use, suggesting that the Eastern Mediterranean may be a primary origin area, especially for species adapted to semi-arid climates. Major plant families including <i>Lamiaceae</i>, <i>Rosaceae</i>, and <i>Fabaceae</i> form distinct clusters that underscore their common ancestry and adaptability, making them foundational to traditional diets and medicinal applications across various environments. Geographical analysis indicates historical connections, such as those between Malta and Egypt, supporting the hypothesis that ancient trade routes influenced the spread and cultural exchange of wild food plant use across the Mediterranean. The study emphasizes the integration of phylogenetic and ethnobotanical perspectives, shedding light on how biodiversity, ecological adaptation, and cultural practices intersect in these regions. This research demonstrates that WFPs serve as both ecological and cultural assets, crucial for preserving traditional diets and supporting biodiversity conservation amid environmental changes. Integrating evolutionary and cultural knowledge can enrich ecological understanding and contribute to the sustainable use of plant resources in the MENA regions.
