Adaptation means the acquisition of attributes that weren't in the previous generations. If polar bears descended from a first living(Life1) cell then that first cell didn't contain the information in reserve to instantiate a polar bear millions of years down the line. The information had to acquired because genes can only contain so much information. This is like believing that computer code can add information all by themselves, which can't be done.
The Wikipedia Aristotelians response to this argument is to induce Infinite regress by proposing that the Pattern or design dichotomy must not be assumed, but then not making it clear what are we then to assume. Leaving questions open ended risks Infinite regression - a formal fallacy.
