http://www.dailymail.co.uk/sciencetech/ ... arted.htmlThe Daily Mail reports today on a scientific study on how the ice age started and continued.
For some reason they call the British Isles 'Celtic' and there is no reference to Doggerland. Which has been replaced with the North Sea.
They don't mention the lack of ice in parts of Ireland which was demonstrated recently by analysing the dna of the Irish mountain hare which is much older than mountain hares from elsewhere and which pre dates the ice age. The same goes for the spruce trees in western Norway which are older than those to the east and match the dna of ancient remains found in pre ice age peat bogs.
However, it does show the southern limit of ice in the south of 'Celtic' which seems to match the direction of the Michael Line.
Perhaps the hardy souls in that part of the world drew a chalk mark in the ground to show where the ice stopped. Or perhaps they built a series of observation posts to keep an eye on it?
