I read that article hundreds of times because it also concerned my ARYAN people. That article came with nothing new, only repeated some basic stuff.
It is saying nothing about the origin of the Assyrian language. I don't think you understand what this article is saying, at all.
By the ways when that article speaks about clustering, they don't mean it on an autosomal level. They are only focused on Y-DNA markers (alleles) and nothing more..
To my own understanding an Assyrian language group was derived from the Akkadian language. When you dive deeper into the origin of the Akkadian language you will find also an origin of the Assyrian language.
The story as I know goes that various Semitic tribes such as Amorites from the Levant and Arabia migrated into southern Mesopotamia mixed with each other and gave rise to an Assyrian language in Mesopotamia that was in turn mostly formed by an Akkadian dialect.
The reason why Assyrians are connected to the Jews is because Semitic tribes Amorites and Canaanites lived next to each other form thousands of years. Amorites migrated into Mesopotamia, while Semitic Canaanites gave rise to the Semitic Jews.
But the thing is that Amorites, Canaanites, Akkadians were all tribes of the similar Semitic race. But when those tribes diverted they started to evolve separately.
So, Assyrians do have a Semitic origin story, you like it or not!
At the end Assyrians are NOT native people to Kurdistan because their autosomal DNA doesn't match well with the ancient native Iron_Age ARYANS from Kurdistan (Lake Urmia region where the ARYAN Kurmanji is from).
Now, just tell us why Assyrians speak a Semitic language while all of it North Western Asian neighbours don’t speak Semitic. It didn’t come out of blue, right?
Why do Assyrians speak Semitic and not Armenian (Urartu) or something?
Also explain to me why Assyrians are also related to other Semitic people in the Levant such as Jews if people of a common Semitic ethnicity as an entity didn’t exist? Why are Assyrians as Semitic speaking population so close to other Semitic speaking people Jews?
Why are you Assyrians genetically and linguistically so close to other Semitic nation such as Jews and Palestinians if a Semitic race doesn’t exists?
Your turn.
