Angela, I usually agree with almost everything you write, but not about the origins of E-V13.
Cardial was Neolithic,
but E-V13 was only found in a single isolated Neolithic sample so far, while many Mesolithic C1a2, F, I*, I1, I2 popped up everywhere among Neolithic G2a samples. So, IMHO, E-V13 and indeed any E-M78 found in Neolithic Europe were assimilated Mesolithic Mediterranean people. Considering the high frequency of E-V13 in the Balkans today, if it had been among the original farmers, it would be found in all Neolithic settlements. That is not the case. If E-M78 had been Mesolithic HG in southern Europe, just like I1 and I2 had been in central and northern Europe, then it makes sense that few E-M78 show up among Neolithic farmers. They were eventually assimilated, little by little, or hid in the forests and mountains until the PIE Steppe people invaded the Balkans, destroyed the towns of Old Europe and caused a population collapse among Neolithic farmers. By then E-V13 ad J2b hunter-gatherers could have re-emerged in the new economy imposed by R1a and R1b invaders. That's what I explained in the
E1b1b page since 2011 and I stand by it.
E-M123, or actually its subclade E-M34, is the only type of E1b1b that I have linked to the Neolithic expansion. I remember mentioning it when
Napoleon was found to belong to E-M34.
The E-V13 is western Anatolia, the Levant, Egypt and Libya can easily be explained by the Greek colonisation, followed by to Roman occupation, followed by the Byzantine rule. Overall that's over 1500 years of Greek or Roman presence in the region. Actually it's surprising that there isn't more E-V13 ! It's harder to explain the presence of E-V13 around Kurdistan, Iran and the Caucasus, except if E-V13 was a minority lineage of a PIE culture. I don't have data about E-V13 in Central Asia and India, but I think it is scarce. Nonethless, Kurdistan also happens to have an unsual amount of East European I2a1, R1a and even J2b, so it is not impossible that a back migration brought all these haplogroups together. Some will claim that it is the impact of the Greek colonisation too, since Alexander and his men had a particular attraction for Babylon, the largest city in his empire. Just speculations though.
No, from Tunisia to Sicily via Pantelleria island, as explained
here.
