"For a calculated 1,400 years, Snaketown was a viable village, but unlike so many tells in the Near East, the people remained the same while their culture changed. The smoothly graded typological sequences for most attributes suggest to me that the ethnic identity of the inhabitants was not interrupted, that they were one and the same people experiencing normal internal evolutionary cultural modifications wtih occasional boosts of features and ideas newly arrived from the outside." —Emil W. Haury
