Had there been such a lake, with the Dover strait area to its south, then the draining of such a lake southward would have left its northern shores high and dry - there would have to be the second land bridge to the north. Thus IMHO his theory does not hold water.

I believe that this is covered by the mentioning of sea levels having changed over time. If the over-all sea level was much lower at the time of this occurrence, then the proposed lake would have a northern shore above sea level. But as the general sea level rose, the northern shore was inundated and didn't necessarily have to be eroded down by some cataclysmic event.

I notice there are no maps showing the before and after. I'm having trouble visualizing this.
