Been watching a Time Team special from a few years back about Doggerland... I've seen it before ages ago, but forgot just how good it was. The stuff the archaeologists know is amazing enough, but some of the bones and tools they've got from the North Sea is truly bizarre given the timescale they've been there. Thing I kept thinking about is that 7000 to 8000 years ago, that isn't that far back in the scale of things... and with the recent discussions about rewilding and all it entails, doesn't the work being done around Doggerland (or what was Doggerland) sort of show that we can only turn back the clock so far? We can't drain the North Sea to reclaim the land, and its unlikely to return unless we have another ice age. What I mean is, wolves and bears, elephants and hyenas... they were probably well at home when we were a landmass attached firmly to mainland Europe... but with the separation... wasn't it inevitable that even those that survived the transition were going to be made extinct?
