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.
前提:野生小麦到现在为止一直在X地,最早的人工小麦遗迹也在X地;
结论:野生小麦是在X地被首次转化为人工小麦;
D: 如果气候产生了巨大变化,那么适应野生小麦的地方就不一定再适应种植小麦了。
因此气候没有什么变化加强说明当时就是在X地转化的,因为条件依然很适合
