This E-V13 surely contributed to the Northwest/East African components we see in the latest results for Iberians.However, it's difficult to say in other parts of Europe (specially around the Balkans) which kind of influence carried. While I expected E1b to show up there, I did NOT expect E1b-V13 to show up in Iberia, if said subclade is today dominant on the Balkans.
The samples are 2000 years older than in Treilles, and identified both G2a and E-V13.
The impact of the Neolithic dispersal on the western European populations is subject to continuing debate.
To trace and date genetic lineages potentially brought during this transition and so understand the origin of the gene pool of current populations, we studied DNA extracted from human remains excavated in a Spanish funeral cave dating from the beginning of the fifth millennium B. Thanks to a “multimarkers” approach based on the analysis of mitochondrial and nuclear DNA (autosomes and Y-chromosome), we obtained information on the early Neolithic funeral practices and on the biogeographical origin of the inhumed individuals. Maternal haplogroups found are consistent with pre-Neolithic settlement, whereas the Y-chromosomal analyses permitted confirmation of the existence in Spain approximately 7,000 y ago of two haplogroups previously associated with the Neolithic transition: G2a and E1b1b1a1b.
These results are highly consistent with those previously found in Neolithic individuals from French Late Neolithic individuals, indicating a surprising temporal genetic homogeneity in these groups.
The high frequency of G2a in Neolithic samples in western Europe could suggest, furthermore, that the role of men during Neolithic dispersal could be greater than currently estimated.
