What was the biggest change in the Earth's atmosphere between the Precambrian and the Paleozoic eras?
The biggest change in the Earth's atmosphere between the Precambrian and Paleozoic eras was the increase in oxygen levels. During the Precambrian, oxygen levels were very low, but during the Paleozoic era, oxygen levels rose significantly due to the evolution of photosynthetic organisms. This increase in oxygen had a significant impact on the evolution and diversification of life on Earth.
