How can we explain J1 dominance in the middle east, especially in the Arabian Peninsula?
From what I read, it originated in northern Mesopotamia and spread southward before Neolithic.
There seems to have a big founder effect in the Arabian Peninsula similar to R1b in the British islands.
For R1b's dominance we can associate it with the spread of new technologies (horses, bronze weapon...) brought by the Indo European, but what about J1?
What could have brought proto semitic people to be so domiant in south-west Asia?

Which haplogroups were in Arabia before J1 arrived? Which haplogroups did J1 replaced?

If I have to guess, I would guess for hg. E, T and L or something.
