This migration occurred during the early human dispersal in the Pleistocene era, when sea levels dropped due to glacial advances, exposing land connections between continents.
The most significant examples of land bridges include:
- Bering Land Bridge: Connected Asia and North America, allowing the migration of humans, animals, and plants between the continents.
- Isthmus of Panama: Emerged during the late Neogene, connecting North and South America, leading to the exchange of biological species.
- Sundaland: Land bridges between Southeast Asia and Australia allowed for the migration of humans and the exchange of fauna and flora.
- Doggerland: A land bridge connecting Great Britain and mainland Europe during the last glacial period.
These land bridges played a vital role in shaping biodiversity, facilitating the movement of species into new environments where they evolved and adapted to the local conditions. Additionally, the migration across land bridges also had cultural and historical implications, contributing to human settlement patterns, trade, and interactions between different groups of people.
