Phylogeography of fruit trees is challenging due to the recurrent exchanges between domesticated and wild populations. Here we tested the eastern refugium hypothesis (ERH) for the carob tree, Ceratonia siliqua, which supports its natural and domestication origins in the Eastern Mediterranean and a feral origin in the West. .
