Answer:
The type of evolution that leads to this phenotype distribution is known as directional selection.
Explanation:
- The process of evolution is a long and gradual process that emerges to exhibit various internal processes like that of the selection of direction, as it plays an important role in the development of organs in a specific manner.
- When a particular species undergoes evolution to withstand the changes that have occurred naturally, the species is also subject to get distributed away from its place of origin.
