Here's why it's a fitting name:
* Movement: At its core, migration is all about movement. Whether it's animals moving seasonally for food or people moving for better opportunities, it's a change of location.
* Regularity: Many forms of migration, especially in the animal kingdom, are characterized by regular, cyclical patterns. Birds migrating south for the winter and returning north in the spring are classic examples.
* Purposeful: While there are exceptions, migration usually involves a deliberate movement towards a specific destination. Animals migrate for resources, breeding grounds, or better climates. Humans migrate for economic, social, or political reasons.
Therefore, the term "migration" accurately captures the essence of this phenomenon – a purposeful and often recurring movement of living beings from one place to another.
