How is natural selection not a random process
WebNatural selection is not random, though the genetic changes (or mutations) that are filtered by natural selection do come about randomly. Some case studies–for example, … WebNatural selection can account for the rise and spread of genetic constitutions, and therefore of types of organisms, that would never have existed under the uncontrolled action of random mutation. In this sense, natural selection is a creative process, although it does not create the raw materials—the genes—upon which it acts. Topic Index.

They began their paper by stating, “Evolution by natural selection is one of the few universal principles in biology” (p. 1677), and they ended by suggesting that quarter-power scaling laws are perhaps just as universal.
WebIn addition, our society has removed most of the natural selection's pressure to adapt to these new activities since we can survive with minimal or no adaptation. This means we are not evolving to improve at writing and reading. Some will, due to random mutations, but most won't. Text is a visual representation of speech, an audial format.
