yes, I find it very confusing@Berun,
Really objective mindset. How about you wait until you see the paper?
everybody giving comments here before the paper is out
I notice a divide in neolithic Iberia.As to yDna...from Olalde et al 2017 on the Spanish "Beaker" samples:
"Iberian individuals with enough data to produce a reliable Y-chromosome haplogroup1882 determination belonged to haplogroups I2a2 and G2 (Supplementary Table 3), bothpresent in high frequencies in European Neolithic farmers124,130–132 1883 and also in Iberian1884 Copper Age populations. Haplogroup G2 probably entered Europe from the Near East1885 during the Neolithic expansion, and haplogroup I2a2 was likely introduced into the1886 Neolithic population through admixture with European hunter-gatherers. Two Iberian1887 individuals belonged to haplogroup R1b but likely not to R1b-L23 and therefore not to1888 R1b-S116/P312. Similar R1b haplogroups were present in low frequencies in Europe1889 during the Neolithic period, as they have been previously observed in both centralEurope (I0559) and Iberia (I0410)124 1890 ."
Eastern and southern Iberia is mostly G2a2.
Western Iberia is mostly I2a.
The Cardial Ware expansion stopped in the Algarve, where it arrived ca 7.5 ka.
The local HG lived in the estuaria in settlements with large shell mounds.
There settlements were seasonal.
There were inland hunting seasons and fishing/shellfish seasons in the estuaria.
Further inland they had megalithic constructions since 8 ka.
When Cardial Ware arrived, the shell mound settlements were abondonned, but the megalithic constructions didn't stop.
The burials in megalithic monuments is remeniscent to the burials in the shell mounds.
The first farmers in Brittain were megalithic. None of them were G2a2, they were all I2a.
Autosomal they were very much like Iberian neolithic.
The Iberian megalithic subclades are I2a-L161 and I2a-Z161, still present in Britain, but extinct in Iberia.
