You&#x27;re trying to insert purpose or intent into what is essentially accident. Most -- almost all -- changes like these either never have lasting consequences or are eventually undone. <i>They are insignificant</i>, and may not even have expression, unless and until they <i>become significant</i> because of subsequent changes.<p>You can insert supernatural interference into the process -- there&#x27;s nothing but the principle of parsimony (Occam&#x27;s razor) preventing that -- but you can&#x27;t <i>require</i> it in order for things to work the way they apparently do&#x2F;did work.
