Context and question: The linguistic heritage of the British Isles is rich, with twelve languages from six groups across four branches of the Indo-European family. The Insular Celtic languages of the Goidelic sub-group (Irish, Manx and Scottish Gaelic) and the Brittonic sub-group (Cornish, Welsh and Breton, spoken in north-western France) are the only remaining Celtic languagesthe last of their continental relations becoming extinct before the 7th century. The Norman languages of Guernesiais, Jerriais and Sarkese spoken in the Channel Islands are similar to French. A cant, called Shelta, is spoken by Irish Travellers, often as a means to conceal meaning from those outside the group. However, English, sometimes in the form of Scots, is the dominant language, with few monoglots remaining in the other languages of the region. The Norn language of Orkney and Shetland became extinct around 1880.
Which language of Gaelic and Shetland became extinct in 1880?
Answer: unanswerable
Context and question: One crucial innovation in reconceptualizing genotypic and phenotypic variation was the anthropologist C. Loring Brace's observation that such variations, insofar as it is affected by natural selection, slow migration, or genetic drift, are distributed along geographic gradations or clines. In part this is due to isolation by distance. This point called attention to a problem common to phenotype-based descriptions of races (for example, those based on hair texture and skin color): they ignore a host of other similarities and differences (for example, blood type) that do not correlate highly with the markers for race. Thus, anthropologist Frank Livingstone's conclusion, that since clines cross racial boundaries, "there are no races, only clines".
Why are variations distributed along clines?
Answer:
isolation by distance
