Cold-adapted species would have already been living in cold areas, which would
have been made even
colder as a result of the post-impact conditions (most likely fatally cold).
Their only hope of survival
would have been to migrate long distances to areas that were once too warm for
them, but were
made 'just right' by the rapid post-impact cooling. Moving long distances
through icy conditions in a
short amount of time isn't easy, especially if barriers like mountain ranges or
large bodies of water
are in your way. Unless of course you happen to be a member of one of those
lineages capable of moving without having to touch the ground. :-)
