There were random changes in points of view, sudden time travel and some awful pacing.
These are random changes, called de novo mutations, that are not inherited.
Averaged over a sufficient period, such random changes accumulate at a constant rate in neutral genes.
"I think there should be limited government, but I don't like random changes," Mr. Walker said.
Creating a human is not nearly as easy as creating an A.I., because we're so very confusingly and unintelligently designed by random changes acted upon by natural selection".
Population geneticists usually prefer to study what are called neutral genes, because they accumulate regular random changes in their DNA, which serve as a useful genetic clock.
Genomes are shaped by mutation -- random changes in the chemical units of DNA caused by radiation or copying errors -- or by the force Darwin called natural selection, preserving the fittest organisms and discarding the rest.
Bacteria can evade destruction through random changes (and there is evidence that even before penicillin was invented some bacteria, through spontaneous mutations, were already resistant to it), or by picking up new genetic material from other bacteria.
Most scientists think that Earth's magnetic field is produced by electric current generated by chaotic eddies in the molten iron of Earth's outer core and that random changes in the eddies cause the reversals.
These six are then used to generate another set of 60, by switching features between some of the images and by making random changes to others.
Selection, mutation, and random changes can be incorporated into such mathematical models to explain and predict the course of evolutionary change at the population level.
