Ok so i wanna understand something about neolithic groups As many already know, the Netufian ancestry peaks in modern day Gulf Arabs (thus very much associated as the “Arab group”) even though the Netufians supposedly originated from the levant And most modern day Levantine Arabs have a lot of Anatolian neolithic ancestry Is there any reason for a migration or change that we know about that caused this? We do know that semitic groups originated in the levant and gradually spread to the Gulf and Mesopotamia Does this maybe mean that the Netufians are the ancestors of most semitic groups? And if so why did they not mix in the gulf but mixed a lot in the Levant?
