Which characteristic defines the Paleozoic era?

Answer 1

The Paleozoic Era is characterized by the emergence and diversification of a wide variety of life forms, particularly in the oceans, as well as the development of early terrestrial ecosystems. It spans from approximately 541 to 252 million years ago and includes key events such as the Cambrian Explosion, which saw a rapid increase in the diversity of marine organisms, the colonization of land by plants and animals, and the evolution of fish, amphibians, and early reptiles. The era is also marked by significant geological and climatic changes, including the formation of supercontinents like Pangaea. The Paleozoic Era is divided into six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
