In nature, selection always uses probability, not truncation. 1 For instance, if we have two wolves, and wolf A has a 1% higher fitness index than wolf B, nearly half of the time, wolf B will be selected over A even though it has a slightly lower fitness value. Wolf A will be selected only 1% more than B on average. This means that 99% of natural selection is wasted for differences like this due to probability noise alone (not even taking into account other noise).
