re: #2 Decatur Deb

Going from memory, I believe there was one into the Middle East (and branching out from there) and possibly a second more eastwards to India and beyond, but all post Neanderthal. One would guess that there had to be another prior, possibly long prior, that gave time for Neanderthals to arise, but I have not seen any speculation on when that could have been.

If we can get a complete enough genome eventually that can probably be answered.
