Coastal spread of the Neolithic in the West Mediterranean

See:
http://www.pnas.org/content/early/2017/01/10/1613413114.abstract

"The earliest dates for the West Mediterranean Neolithic indicate that it expanded across 2,500 km in about 300 y. Such a fast spread is held to be mainly due to a demic process driven by dispersal along coastal routes. Here, we model the Neolithic spread in the region by focusing on the role of voyaging to understand better the core elements that produced the observed pattern of dates. We also explore the effect of cultural interaction with Mesolithic populations living along the coast. The simulation study shows that (i) sea travel is required to obtain reasonable predictions, with a minimum sea-travel range of 300 km per generation; (ii) leapfrog coastal dispersals yield the best results (quantitatively and qualitatively); and (iii) interaction with Mesolithic people can assist the spread, but long-range voyaging is still needed to explain the archaeological pattern."

The actual paper is behind a pay wall, unfortunately, as I would like to see more about the interaction between the Mesolithic people and the farmers.

The appendix is the only other thing that's available.

not much European mesolithic DNA, neither Y nor mt apart maybe from the I2a1b1 in Els Trocs and just a few mtDNA U and U5

I like this map (figure 1), it shows how far inland Cardial Ware people went into Spain 5600-5000 BC

Abstract
The spread of agriculture in the Iberian Peninsula is documented from at least ca. 5600–5500BC, although botanical data are absent or very limited for large areas. Archaeobotanical information shows from the beginning an imported agrarian system with a great diversity of crops: hulled and naked wheats and barleys, legumes such as pea, lentil, fava bean, vetches and grass peas, flax and poppy. This diversity of plants with different requirements, processing and uses, implies that the first farmers quickly imported or acquired a wide range of agrarian knowledge. Regional and inter-site agrarian differences are discussed in relation to factors like ecology, culture, use of the cultivated plants and management of the risk of crop failure. The adoption of farming resulted in significant ecological, economic, dietary, and social changes for the Neolithic people of Iberia.

Els Trocs is also in this area
(near location 1)

apart from Spain there was also spread along the Portuguese coast upto halfway north

I don't know if you've ever seen this:
https://www.researchgate.net/figure...ctions-GARP-produced-A-Impressed-Ware-culture

I know how to get passed paywalls.

Btw, all the ancient European mtDNA and Y DNA data one would ever want is here....

Ancient Y DNA, mtDNA
Haplogroup Frequencies

Very useful tables but need some updates now...

It would be nice if the linkages between archeology and the big data dna are more being estahablished. More integrating is needed. Bridging two worlds.......
But may be it's my lack of knowledge.

Open question: in which recent articles/ literature is the connetion between archeology and big dna data perfect?

I'm not sure I understand. For just one example, the spread of the Neolithic in Europe is extremely well documented. It was always known from archaeology and assorted disciplines that the domesticated plants and animals and housing and way of life in general was developed in the Near East. The only question was whether it traveled to Europe through cultural or demic diffusion. Now we know through genetics that it was people who brought the technology.

Genetics is in fact answering some of the questions which archaeology could not answer.

I understand the dilemma's and the cultural package vs. the immigration routes.

But sometimes I get the impression that DNA whiz kids with supreme knowledge of archeology and vice versa are rare. You can't describe history and historic devolopments bij spreadsheet. Otherwise some archeologist or historians of pre historic times don't have a notion about the possibilities of DNA data. Or simply ignore it when you only consider the "cultural option". Sometimes alpha vs. beta thinking.

I very much agree with that. There are indeed a lot of archaeologists who are resistant to the "intrusion" of genetics into their field. On the other hand, there are a lot of population geneticists who are woefully uninformed about archaeology and history. The lack of such knowledge in the "enthusiast" community is at another level entirely.

I think there has been some attempt by the Reich team to harmonize the two, as when David Anthony was a co-author on one of their papers. The problem is that sometimes the findings of genetics contradict conclusions reached by archaeolgists, anthropologists, linguists. etc.

What updates?

Basicaly this confrontation could deliver the best kind of research and articles because this stimulates to open some old bubbles.....out of the box.

I guess the leapfrog didn't stop at Gibraltar [emoji1111] but went on into the Atlantic coast and up to Southern Scandinavia (K15 Gedmatch Eurogenes).. http://dienekes.blogspot.nl/2012/04/ancient-dna-from-neolithic-sweden.html Bell Beakers did have considerable amount of Atlantic and West Med. But obviously this was already a Funnelbeaker heritage.
