Nature doesn't pursue progress. It fosters any (at least some) that might appear but it doesn't actively pursue it. If it did, there would be instinctual drive to seek out ionising radiation proportionally to the amount of offspring for particular species. To iterate as fast as possible and get any edge in selection.
