thinking about it, there could be a strong possibility that a large number of mutations at one time could affect the rate of evolution, and not necessarily increase it.
the higher the number of mutations in an individual, the more likely it is for a lethal mutation to occur. and even if an advantageous mutation did occur as well, it could very well be masked by the death of the individual due to the lethal mutation.
So intimate that your hand upon my chest is my hand,
so intimate that when I fall asleep it is your eyes that close.
- Pablo Neruda
