For a long time it was believed that, thousands of years ago, Central Europe was covered with almost uninterrupted primeval forests.
Squirrels could cross these forests from the Alps to the North Sea without once touching ground – or so the common assumption was.
Until the humans came and cleared the forest to get wood and make way for arable and pasture land.
It is possible, however, that the natural landscape looked more diverse than assumed even without human interference.
Perhaps like that! …. Or like that!
How do we arrive at this conclusion and what does it mean for the present time?
