Summary
Fig fruits discovered in the Lower Jordan Valley predate cereal domestication by 1,000 years. This suggests early Neolithic fig trees may have been the first domesticated plant, revolutionizing agriculture.
Area of Science:
- Archaeobotany
- Neolithic Studies
- Plant Domestication
Background:
- The Near East is widely recognized as the origin of early plant domestication.
- The Neolithic Revolution marked a significant shift towards agriculture and settled lifestyles.
Observation:
- Nine carbonized fig fruits and numerous drupelets were unearthed at Gilgal I, an early Neolithic village.
- The archaeological site in the Lower Jordan Valley dates back 11,400 to 11,200 years ago.
Findings:
- The discovered fig fruits suggest intentional cultivation and harvesting.
- Evidence points to the use of parthenocarpic fig trees propagated from cuttings.
Implications:
- Fig trees may represent the first domesticated plant, preceding cereals by approximately one millennium.
- This finding challenges the traditional timeline of the Neolithic Revolution and early agriculture.

Introduction to Seed Plants
Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms.
Seed Structure and Early Development of the Sporophyte
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.
Fruit Development, Structure, and Function
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
Rab Cascades
Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.
