The era that marks a significant increase in the complexity of life, particularly with the diversification of marine life and the emergence of plants on Earth, is the Paleozoic Era. This era began around 541 million years ago with the Cambrian Period, known for the "Cambrian Explosion," when many phyla of marine organisms rapidly evolved. The Paleozoic also saw the first land plants appear, contributing to the complexity of ecosystems.
