A new paper posits "an approximately linear dependence between the age and the geodesic distance from the Near East, suggesting a systematic (but not necessarily uniform) spread at an average speed of about 0.65 km/yr. "
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0095714
In comparison, the rate of spread into Europe has been computed as 1.0 km/yr. (Cavalli-Sforza)
That would seem to comport with genetic data previously published. I found it interesting that the spread wasn't impeded very much by the relatively unfriendly terrain through which it had to pass.
The most interesting aspect to me, however, was the list of dates for the various Neolithic sites that was provided in the Appendix.
Some of them are incredibly old...these are all B.C.E. dates...so over 12,000 years old.
Gesher 10,458
Cayonu 10,368
Coga Bonut 10,125
Abu Madi 9,589
This is the site of Gesher, by the way...
Coyonu, very similar in age, is in eastern Anatolia, while Abu Madi is all the way in the southern Sinai. An amazingly quick spread in this area it seems to me.
