Hello, how are you? I hope you are doing well.

I have recently been delving into the field of genetics—a complex subject. I read a great deal about it, accepting some findings while questioning others, but I have reached a point where I am stuck. The issue is as follows: I observed that the oldest gene found in the Fertile Crescent (southeastern Turkey, Iraq, and the Levant) is Haplogroup G, whereas the oldest sample found in the Caucasus is Haplogroup J. I find this quite surprising. Please provide a logical, scientific response regarding the accuracy of my observations.
