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
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.
