J1 couldnt have reached arabia in 7000 bc, thats one mistake among many I suspect, and he also seems to illustrate that I2a1 retreated to the dinaric mountains because of incoming R1b which is most likely false given the time for recent common ancestor of the I2a-Din group which is 2300 years.
and he is also giving my group a place in the world (the last map in southern Armenia I2*) which is ridiculous, he doesnt appreciate the rarity of my ancestors who never transcended the 1% barrier anywhere. He should give that place to some R1b or J2 subclade.
