Chapter 29, Problem 1QSDC
Summary Introduction
To review:
Evolution as a random process or not.
Introduction:
Evolution is the process of change in a population of organisms in a particular species or in multiple species which are subjected to environmental change. These evolutionary changes are heritable. These changes over multiple generations cause the evolution of species.

Evolution, which involves genetic changes in a population of organisms over time, is often described as the unifying theme in biology. Discuss how evolution is unifying at the molecular and cellular levels.
Explain:
"Mutation is random;natural selection is the very opposite of random"
If we lived in a world without mutation, then we will not have evolution.
