爱尔兰蜗牛与欧洲旧石器时代猎人的迁徙

Irish Cepaea nemoralis Land Snails Have a Cryptic Franco-Iberian Origin That Is Most Easily Explained by the Movements of Mesolithic Humans

The origins of flora and fauna that are only found in Ireland and Iberia, but which are absent from intervening countries, is one of the enduring questions of biogeography. As Southern French, Iberian and Irish populations of the land snail Cepaea nemoralis sometimes have a similar shell character, we used mitochondrial phylogenies to begin to understand if there is a shared “Lusitanian” history. Although much of Europe contains snails with A and D lineages, by far the majority of Irish individuals have a lineage, C, that in mainland Europe was only found in a restricted region of the Eastern Pyrenees. A past extinction of lineage C in the rest of Europe cannot be ruled out, but as there is a more than 8000 year continuous record of Cepaea fossils in Ireland, the species has long been a food source in the Pyrenees, and the Garonne river that flanks the Pyrenees is an ancient human route to the Atlantic, then we suggest that the unusual distribution of the C lineage is most easily explained by the movements of Mesolithic humans. If other Irish species have a similarly cryptic Lusitanian element, then this raises the possibility of a more widespread and significant pattern.

在冰期寒冷气候下,爱尔兰是没有蜗牛的。英国与法国还连着的时候,爱尔兰已经成为岛屿了。看来它的蜗牛只能是外来的。记得北美的蚯蚓有类似的情形,不知爱尔兰的蚯蚓如何。

这篇无非是印证了爱尔兰早期的移民和属于从西班牙西部渡海而来的伊比利亚人。和威尔士的早期居民应该是一样的。我记得看过的爱尔兰历史中有凯尔特人来到爱尔兰之后看到当地土著是皮肤较黑并且吃蜘蛛(估计是带歧视的说法)的人。

考古的证据:
爱尔兰新石器时代人群,属长头、身材矮小型,与后期罗马人有点类似;青铜时代,是另外一批人。
很外行的估计一下,爱尔兰新石器时代人群基因标记应为 G。

这是猜想而已
其实爱尔兰新石器时代还是相当复杂的。巨石文化长头型居多,非巨石文化短头型为主。一般认为长头型是土著,短头型是外来。短头型应该来自大口杯文化群。期间,还有一些火葬墓,什么类型,无法获知。青铜时代末期,日耳曼人压迫凯尔特人,凯尔特人进入爱尔兰。综合:罗马人的记载和巴斯克人以及百越上面的说法,可以基本确定现代爱尔兰的高大肤白棕发等特征均属前300(有些认为前1000)凯尔特人的基因,还有后来的日耳曼、维京人的基因。
