The Cenozoic or "recent life" era
During this era, familiar marine life forms such as fish, sharks, and bony corals evolved. These organisms played essential roles in shaping marine ecosystems and diversity during this time.
Mammals evolved adaptations that allowed them to live on land, in the air, and in the water during the Cenozoic Era. The Cenozoic Era began approximately 65 million years ago.
Angiosperms They produced seeds that are protected they are the most diverse and abundant land plants today. Present day angiosperms that evolved during the mesozic era include magnolia and oak trees.
Humans appeared during the Quaternary period of the Cenozoic era, which began around 2.6 million years ago. This era is marked by the development of modern human species and the emergence of Homo sapiens.
During the Paleozoic Era, the first land plants, insects, fish, amphibians, and reptiles evolved. This era also saw the evolution of early mammals and the diversification of life in the oceans. The end of the Paleozoic Era was marked by a mass extinction event that wiped out many species, paving the way for the rise of new organisms in the following eras.
Humans are thought to have evolved during the geological epoch known as the Pleistocene, which began around 2.6 million years ago and ended approximately 11,700 years ago. This period was marked by multiple ice ages and significant changes in climate and environment.
Cenozoic Era :)
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.
Cenozoic era
The first homonids (animals from the same genus as people) evolved about 3 million years ago. Our species, Homo sapiens, evolved about 200,000 years ago. All of the time since the dinosaurs died out 65.5 million years ago is called the Cenozoic Era, thus humans evolved in the Cenozoic.

Humans evolved in the Pleistocene era, which is the most recent part of the larger Cenozoic era. Modern humans first begin appearing in the fossil record approximately 200,000 years ago.
Jellyfish and other multi-cellullar organisms evolved during the Cambrian era.
Precambrian
Ferns were not introduced but evolved during late Paleozoic Era .
there were no humans
No. The dinosaurs rose in the Mesozoic era. The end of the Mesozoic era was also the end of the dinosaurs. The era following is the Cenozoic, which we are still in today.
