Honey, about that hike to France we planned ...

In August of this year, archaeologists reported the discovery of the oldest-known house in Britain -- 6,000 years older than Stonehenge.

It was built, they said, when Britain still was connected to continental Europe.

That gets me thinking. That means there had to be some particular day when humans in Britain woke up and discovered that they were suddenly upon an island. What was their reaction? Was it cataclysmic -- suddenly a churning channel where children had picked flowers the day before? Or was it an oh-so-gradual rise, with a few inches of water between France and England building to its current depth over the course of centuries?
