Who were the ancient Sumerians?

The ancient Sumerians were highly advanced and likely had more knowledge about a multitude of things than people in Medieval Europe had. Those people were advanced in technology, mathematics and medicine. They were able to figure out what is now considered obvious, but wasn’t prior to them. It is necessary to note that society changed in ancient Sumer. The 3rd Dynasty of Ur for example is likely the origin of the ancient Hebrews.
Many cultures came from the Sumerians. They were losing ground eventually and tribes built and left. What were their blood type frequencies? Where did the ancient Sumerians come from?
Do they have some common ancestry with the Yamnaya?
When looking at King Tut for example, his blood type A2 could have Sumerian ancestry. From Sumer, many left and brought their knowledge to other worlds. The look of the ancient Sumerians is also of interest. There likely has been a mix of all types of hair and eye colors. We may or we may not be able to trace them all back, but it isn’t necessary to know exactly what their gene pool looked like, because when we are ready to examine the tribes that come from them, then it is time to do that.
Red hair may have been frequent or not, but it was at least present as it is in the Kalash people today. The Kalash people are remnants as are many. So wondering what the ancient Sumerians may have looked like isn’t necessarily the way to go. They had different looks. These looks date way back to original looks and mutations more recent. Blood type frequencies are of great interest to me, but I am not sure what they were.
Nordic people are completely different. People confuse both for similar based on complexion, eye color. Blond hair and red hair have completely different origins. Europe consists primarily of Nordic and Celtic people. The Nordics were likely low in rh negative blood. The Celts high. The Celts originate from the original Aryans (Yamnaya). The Nordics were the fake Aryans.
The Aryans are not considered the Yamnaya by many. Many who don’t look back further. Aryans are a mix of populations, so looking back further and at their variety of origins is key to determining the History of the World through the Eyes of Blood.
