- Observation Olive, grape, date and fig were the first important horticultural additions to Mediterranean grain agriculture.
- Observation These fruit trees were most likely domesticated in the Near East in protohistoric time.
- Observation The fruit trees became important food elements in the early Bronze Age.
- Mechanism Simple vegetative propagation made the four fruit trees preadapted for early domestication.
- Mechanism Clonal propagation limited selection and fruit set under cultivation.
- Observation Each classic fruit tree has interconnected wild, weedy, feral and domesticated types with occasional hybridization.
- Mechanism Introgression from diverse wild gene pools facilitated variation in domesticated crops.
