    Outstanding cases, however newsworthy, don’t give you any idea about the distribution. If they were saying, for example, the median water crossing had increased from 5 miles to 20 miles and the number required had also doubled, that would give you some idea of the change. Although you’d still be guessing at the practical impact …

  2. It also demonstrates that evolution has given at least some polar bears the ability to swim for nine days, which implies that they have had the occasional need to do so for thousands of years, and this is perhaps not a new thing.
