What life form evolved during the Paleozoic era cyanobacteria humans reptiles or dinosaurs?
During the Paleozoic era, cyanobacteria evolved and thrived, playing a crucial role in the Earth's early ecosystems by contributing to oxygen production through photosynthesis. While reptiles and dinosaurs appeared later, during the Mesozoic era, cyanobacteria were among the earliest life forms to exist on Earth, significantly influencing the planet's atmosphere and biological diversity. Humans, on the other hand, evolved much later, during the Cenozoic era.
