“...These include vessels large enough to make 43 gallons of beer or porridge...the absence of remains of domestic grain at Göbekli Tepe isn’t conclusive proof that people there weren’t planting crops.”
Was grain cultivated on-site even necessary for beer or for flour? Women might harvest wild and plentiful Einkorn, with a 30K year history, or Emmer, which required pounding with mortar and pestle to release the seeds. Water and a sugar source like honey and yeast off the surface of dates, and there’s your beer.
the site is much larger than originally thought. The same kind of thing happened in the 1950s-60s with the Catal Huyuk site -- the digging just happened to encounter a shrine with various human and animal skulls. The site was occupied for over 1400 years and abandoned over 7500 years ago.
Multirow barley was developed at least 14K years ago, in Anatolia, and as you noted, other grain crops have been available for a long while.
The fact is, I've never seen much value to this artificial, modern division of hunter-gatherer vs farming. :^)
