...and before the last Ice Age????... I'm hoping you're not thinking that is were time started or that these tortoises did not exist before that Ice Age. They probably did not move into but back to those areas. If global warming continues it wouldn't be a stretch to think they would expand their range which is another hint that temperature is a major controlling factor in their movement... I'll get back to you in the next 15'000 years.
To my last line... any good reference to any 'fact' in biology should always have wiggle room. Probability is the best you are going to do in biology... this is why every good reference paper that is trying to prove something is going to have the statistical data to back it up.
There is always going to be that odd individual that refuses to get with the program and that individual either adapts... or... dies out.

Also you say probably wouldn't hibernate, thats not a stone cold fact, its opinion.
