> When thinking about the dating of agriculture it is important to remember that Göbekli Tepe was rediscovered rather than discovered. In October 1994, the archaeologist Klaus Schmidt was reviewing archives of known sites, trying to decide where to dig next. A site description caught his attention: a hill that had first been excavated in a 1963 survey by the University of Istanbul and the University of Chicago, but abandoned soon after.

Heh. A much less prosaic version of the story with the mulberry bush in OP's article.
