The two cultivated rice species are separated by a very strong reproductive barrier. Reproductive isolation between the two species, given that they have been in each other's presence, has been particularly effective, as evidenced by the absence of reciprocal introgressions. Another possibility put forward by the concepts and methods of population genomics is the modeling of the spread of a cultivated species from its area of origin, and thus the possibility of statistically determining this area of origin. One way of clarifying certain open questions, such as gene flow between the wild and cultivated groups, would be to use archaeological samples with ancient DNA sequencing methodologies, which would enable us to better trace genomic evolutions throughout the initial domestication process. Despite recent technological advances and the contribution of genomics, there are still many areas of uncertainty concerning the history of rice domestication.
