The differences in beak shape are examples of:

Explanation:

Bird beaks are textbook examples of BIOLOGICAL adaptation to diet, but their shapes are also controlled by genetic and developmental histories.

The first one is bacterial because it mutates very quickly compared to humans and the second one is biological adaptation
