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.
yet不是有否定意味吗? 举个例子: have yet found 表示 还没有找到。
按照答案理解的意思是“由于目前发现的最古老的栽培小麦遗迹来自同一狭长地带的村庄遗址”,那yet在此的作用是什么?
