一道题求解！

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?
(A) 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.
(B) Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains.
(C) At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated.
(D) 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.
(E) 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.


答案为D，很困惑。。。逻辑链应该为：wild 和 cultivated都在一个地方被发现------> 所以这个地方就是第一个把emmer domesticated的地方，和D说的气候有毛关系？！

1）如果climate condition 不一样,可能导致wild form of emmer 是后来长的，说明这里以前可能没有wild form。
2）first domesticated的地方需要从wild form 到cultivated。
3）所以cliamte condition如果不一样，削弱了事实：这里以前有wild form。就削弱了结论。。。。
4）上面是猜的啦啦啦啦~~其实我也不太确定
