The maternal genetic make-up of the Iberian Peninsula between the Neolithic andthe Early Bronze Age
Anna Szécsényi-Nagy et al (including Guido Brandt and Wolfgang Haak)

"Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focused on the maternal genetic makeup of the Neolithic (~ 5500-3000 BCE), Chalcolithic (~ 3000-2200 BCE) and Early Bronze Age (~ 2200-1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central, southeast and southwest regions and thus on the largest archaeogenetic dataset from the Peninsula to date. Similar to other parts of Europe, we observe a discontinuity between hunter-gatherers and the first farmers of the Neolithic. During the subsequent periods, we detect regional continuity of Early Neolithic lineages across Iberia, however the genetic contribution of hunter-gatherers is generally higher than in other parts of Europe and varies regionally. In contrast to ancient DNA findings from Central Europe, we do not observe a major turnover in the mtDNA record of the Iberian Late Chalcolithic and Early Bronze Age, suggesting that the population history of the Iberian Peninsula is distinct in character."
Well, from my cursory first reading of the paper, the hg mtDna is more than in Central Europe, but there's still not very much of it. That roughly 20% autosomal hg present in European populations of the late Neolithic/Chalcolithic seems to have owed more to incorporation of male hunter/gatherers than female hunter-gatherers, if we can extrapolate from the increasing appearance of I2a among the European farmers.
It also appears that there was no movement into Iberia of more "steppe like" women as of 1500 BC.
