Other claims from this paper (6)
- Observation Across the Early Harappan to post-Indus periods, the proportion of domesticated-type rice spikelet bases increased progressively at three north-west Indian settlements.
- Observation The proportion of wild-type rice spikelet bases decreased over the same period.
- Observation The accompanying weeds comprised a mix of wetland and dryland species.
- Mechanism The development of an independent rice tradition may have been intertwined with the practices of the eastern-most Indus peoples.
- Mechanism The pattern fits a slow development of rice exploitation from wild foraging to full cultivation.
- Observation When Oryza sativa ssp. japonica arrived around 2000 BCE, the area was already familiar with domesticated rice cultivation and a range of cultivation techniques.
