Below is an overview of these major regions and what sets them apart. Understanding these realms is essential for grasping how geography, climate, and deep time have shaped the planet's biodiversity.
Neotropical Realm: Unparalleled Life Richness in a Unique Biogeographic Zone
These realms are determined by distinct geological histories, climate regimes, and the presence of specific biotic provinces. It encompasses the vast Amazon basin, the intricate landscapes of Central America, and the unique ecosystems of the Caribbean.
These large-scale patterns form the foundation of biogeographic realms , the broadest units used to categorize the distribution of the world's ecosystems and organisms. The ancient connection of South America to Antarctica and subsequently to North America via the Isthmus of Panama dramatically reshaped its biological composition through the Great American Interchange.

These boundaries often align with geological barriers like oceans, mountain ranges, and vast deserts, which prevent species from migrating and mixing. Life on Earth does not distribute randomly.
