The archaeology journal concludes that the pots were spread by migration, not trade. To support the conclusion, the journal provides these following evidences: (1) high levels of a certain metallic element have a strong association with people who migrated after childhood; (2) many of the bones founded near the pots contain high levels of the metallic element. I cannot agree with the journal in neither of them, forthey are scant enough evidences to convince me, and beyond them other possibilities might exist.
The first problem with the journal involves the metallic element contained by various food was unnecessarily absorbed by people who migrated to a new place after childhood, which might flow out of the body of those people directly. In contrary, people who might not migrate in all their lives, but for their bodies possessing a special function, can absorb a certain metallic element contained in various foods. The journal is absent sufficient evidences to rule out the possibility, so just analysis of the bones of prehistoric human skeletons is meaningless.
Even if assume that the high levels of a certain metallic element have some relationship with people who migrated after childhood, I still cannot agree with the other evidence provided by the journal that just at a few sites many of the bones near the pot show high levels of the metallic elements, but not all the sites. A few sites might be the exception, while most of the sites couldn’t be found out the bones contained a certain metallic element, so it is likely that the spot was spread by tread.
However, the reason why the ceramic pots at various prehistoric sits sitesscattered over a wide area cannot rule out these possibilities: first, the technology of making the ceramic pots may hadhave been transferred widely, for that reason pots makers made lots of pots over a large area; given making pots 没明白is not a aneasy job, especially at that time, the reason might be partially for the development of trade, which can scatter these ceramicceramics over a wide area, partially for the spread of the technology. Both of the reasons can account for the wide spread of the ceramic pots, so the journal's conclusion thatthe spread of the pots must be by migration is hasty.
To sum up, the journal is simply not credible, at least based on the report. These evidences provided by the journal are questionable, the journal should provide more information about the association between the high levels of metallic element in various foods and the migration of people after childhood. If possible, more archaeology materials about the discovery of the ceramic might can去掉help assess the journal.
主要改了些语法而已,好容易找到一篇和我用的模板一样的,很亲切撒.
