For decades, archaeologists reconstructing the origins of agriculture in the Fertile Crescent relied predominantly on macrobotanical remains—charred seeds and chaff recovered through flotation techniques. Because charred grains of domesticated barley (*Hordeum vulgare*) possess distinctive morphological traits, such as non-brittle rachises that prevent seed dispersal prior to harvesting, their presence was long treated as the definitive boundary marker for agricultural commencement. However, this methodological reliance created a systematic sampling bias: carbonization requires accidental exposure to fire, a condition far more prevalent in settled, permanent hearths than in the ephemeral seasonal encampments of pre-domesticate foragers. Recent analyses of phytoliths—microscopic silica bodies formed within plant tissues that persist in soil long after organic matter decays—have disrupted this established timeline. Unlike fragile macrofossils, phytoliths assemble in diagnostic configurations across both wild and domesticated varieties without requiring pyrotechnic preservation. Phytolith evidence from pre-Neolithic strata indicates that intensive exploitation and morphologically subtle manipulation of wild cereals preceded by several millennia the structural rachis mutations visible in macrobotanical assemblages. Consequently, the transition to agriculture is now understood not as a rapid technological threshold marked by morphologically altered seeds, but as an extended continuum of ecological management.
