What Is characterized by the first land-dwellers and mdashplants and amphibians?

The first land-dwellers, characterized by plants and amphibians, represent a significant evolutionary transition from aquatic to terrestrial life. Early land plants, such as mosses and ferns, adapted to survive in dry environments, while amphibians, like early frogs and salamanders, evolved from fish and developed the ability to thrive both in water and on land. This period marked the colonization of terrestrial ecosystems, leading to diverse plant and animal life and the establishment of complex terrestrial habitats.
