At last the proof.

The spread of domestic animals through time is one of the topics studied by archaeologists to assess human trade and migration. Here we present mitochondrial analysis of 42 archaeological cattle (Bos taurus) bone samples, from 16 different sites in the Iberian Peninsula and covering a broad timeframe (from the early Neolithic to the Middle Ages), to provide evidence about the origin and dispersion of the T1 cattle haplogroup in relation to human contacts and movements. The presence of the T1 haplotype in one sample from an early Neolithic site close to the Mediterranean coast of Iberia, and its continuing presence in the Peninsula during Roman and Medieval times, clearly demonstrates that T1 was not solely a Muslim or later introduction. Rather, our molecular data show evidence for a pioneer coastal colonisation of the Iberian Peninsula from the Mediterranean basin, followed by possible further colonisation, leading to a continuity of diversity through time.

A North African Neolithic route perhaps.

That is what I have assumed for some time. It fits with archaeological evidence of early farmers arriving in some places in Iberia from North Africa even earlier than the Cardial Ware arrivals.

So then the query (Maghreb to Iberia) is a possibility. http://www.anthrogenica.com/showthread.php?3831-The-Out-of-Maghreb-Hypothesis-for-Western-R1b&p=82896&viewfull=1#post82896

For Lactase Persistence? No. The chronological gap remains between the first arrival of cattle in Europe in the Neolithic and the appearance of 13910T, whichever of the three farming routes into Europe we consider. http://www.ancestraljourneys.org/autosomaladna.shtml

The whole idea that Lactase Persistence must have arrived with the first farmers was based on anti-migrationism. Archaeologists did not believe that there were any major migrations into Europe after the Neolithic. That basic premiss has been destroyed. We now know that there were migrations after the Neolithic. So to solve the puzzle of why no 13910T has been found in the LBK, it is pointless to just focus on a different farming route into Europe. LP is no earlier in Iberia.

Instead we need to recognise that LP is connected to dairy farming specifically - a later specialisation.

There is a possibility then that some of the mtDNA haplogroup H subclades may have arrived in Iberia from North Africa during the Neolithic or maybe even earlier in some cases since certain subclades such as H1 reach very high frequencies in North Africa. I know that the frequency of a haplogroup in a certain region does not mean that it originated there but the pattern of the distribution of H1 looks like there may actually be something to this.

Since the farmers were all from the same source - the Near Eastern Neolithic - whichever route they took into Europe, we are likely to find the common Neolithic Near Eastern mtDNA haplogroups arriving all over the place with farmers. There is H1 in the LBK:
http://www.ancestraljourneys.org/europeanneolithicdna.shtml

As far as I can see, mtDNA H first expanded (developing a lot of subclades) in the Near Eastern Neolithic. So a number of its first-level subclades, like H1, would have been present in the Near Eastern pool from which farmers left for Europe and North Africa (and elsewhere).

We may need to look at Middle and Late Neolithic farming cultures that practised a lot of dairy farming for the origins of 13910T.
