Traces of cultivated emmer wheat have been found among the earliest agricultural remains of many archaeological sites in Europe and Asia. The only place where the wild form of emmer wheat has been found growing is a relatively narrow strip of southwest Asia. Since the oldest remains of cultivated emmer wheat yet found are from village sites in the same narrow strip, it is clear that emmer wheat was first domesticated somewhere in that strip.
Which of the following, if true, most strengthens the argument?
The present-day distribution of another wild wheat, einkorn, which was also domesticated early in the development of agriculture, covers a much larger area of southwest Asia.
Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains.
At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated.
In the region containing the strip where wild emmer wheat has been found, climatic conditions have changed very little since before the development of agriculture.
It is very difficult, without genetic testing, to differentiate the wild form of emmer wheat from a closely related wild wheat that also grows in southwest Asia.
看到这条之前的没质量纯吐槽也是笑翻了，好吧重新回答一下。premise：野生小麦驯化后是驯化小麦。野生小麦大目前为止还在生长的只有SA地区，这一地区也是现存最古老的驯化小麦被发现的村镇遗址所在地 conclusion：小麦是在这里驯化的。为什么环境不变就能加强结论呢？这里有个前提没有点破，野生小麦有可能不能适应气候变化前的这一地区的气候。这说明野生小麦有可能不是这一地区最早拥有的，而是传播过来的。（野生小麦是从现有野生小麦同一气候环境的地区传播过来的）这里又有一个前提没有点破，野生小麦都不是这里先发现的，自然驯化小麦也不是这一地区先做到的。
