This finding doesn’t mean that camels weren’t brought in during earlier periods but not adopted/domesticated until later.
Camels have been around for tens of thousands of years. They were used by migratory/trading people for possibly thousands of years before they were “domesticated” in the newly settled areas of the Middle East.
By the way, Camels are not kosher, and my son, who encountered them in Iraq, say they stink like a cesspool.
My late grandmother did ride a camel in the old Palestine in the 1920’s, and then smoked them for years.
Remember the old joke? How do you like your camels, one hump or two? Neither do I.
I wonder how many remember the old ad: “I’d walk a mile for a camel”.
Camel meat from young camels was sold in suqs back in the 70’s when I lived in the ME.
Tastes like beef when the camel is young. Nothing weird or smelly about it.
