| Outline of Final Research Achievements |
In the final year, we gathered and compared the size data of carbonized seeds and seed impressions during the Jomon period. The results show that the seed size increased from 6000 to 4500 years ago both in soybean and azuki. We assumed that the domestication was probably occurred during the time period, because the seed size gradually increased in 1500 years, and the seed size expanded over the size range of modern wild species. Geographically, the seed size enlargement have been occurred in the central highland of Japan. However, we do not know why the seed size enlargement has been occurred in that time period and in that geographical region. There is a possibility that the seed size enlargement episode was linked with population increase in the region. We have to continue further archaeobotanical, experimental and genetic studies to test the hypothesis.
