Physical differences in beaks of birds would develop as a result of different environmental changes.
<h3>What is Evolution?</h3>
This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.
