Yep..
But imagine this situation:
Let's say, the temperature of the environment has gone up.
This change of the environment will cause DNA more prone to mutation (it is not hard to understand why - atoms are moving more violently at higher temperature and it is easier for some of them to move out from where they were or to create other bonds with neighbours).
Now, the resulting mutation, from the DNA information point of view will have nothing to do with the resistance of the cell to higher temperatures - it may have quite the opposite effect... or the effect can change some totally unrelated property (colour of the cell... or it may grow a horn on one side). And if the temperature stays high and if it is lethal to a cell, it will die.
But, just one in thousand mutations may have right effect - increased resilience to higher temperature.. and cell's offspring survive and multiply further in changed environment.
This is the example of RANDOM mutation(s) of the DNA that resulted in adaptation of the species to a new environment.
No paradoxes....
