Was there ever a land bridge between Northern Ireland and Southern Scotland?

Wow. I have no knowledge what the subaquatic geography is like there.
That is a poser.
I look forward to seeing what sort of educated answers you get here.

Here’s an excerpt from an article about the probable existence of Doggerland:

You may have seen reports of the discovery of the “British Atlantis” circulating the web. Those stories seem to have been sparked by a new display of recent research at the Royal Society and especially this article which has some good images. Briefly, what has been found is further evidence that between Great Britain and western Europe there used to be no sea but dry land that was inhabited by a community of ice-age animals and plants including probably human populations. This is not a new idea but new technology and renewed human efforts have led to the discovery of much more evidence to support this hypothesis. I find the articles to be too fluffy and so it is difficult to say how certain we can be that what is now the sea floor was inhabited by communities of people and not just plants and other animals but it seems quite certain that Great Britain and Europe were connected by dry land in the past.

From what I can see on the map, there was a narrow inland body of water between northern Ireland and Scotland, but apparently the land bridge extended past both ends of it.

The evidence seems mixed. The similarity of plant and animal life in Scotland and Ireland suggests there was a land connection but seabed geology is against it. While the sea level dropped globally by 130 metres as water became locked up in glaciers the weight of ice in Scotland and Ireland depressed the land so much that the water in the channel between Ireland and Scotland fell by no more than about 30 metres.

Interesting article and papers @Brian1946 & @flutherother. The Irish Times one mentions “Recent work by a namesake, Trinity botanist Fraser Mitchell, on the northward migration of trees, suggests a direct route from Spain, rather than westwards from Britain. This and the timing (pine arrived in the south-west of Ireland 9,500 years ago)...” Which, in my way of thinking anyway, would also go a long way to explaining the Irish/Basque DNA similarities.

Anyone know of a user friendly website that allows one to play with various sea levels/land configurations?

Following; researching; response to come.

(nudging @Strauss) hey! How’s that research coming?

Haha…
