Fossils of fish appeared approximately 500 mya during the what?
Fossils of fish appeared approximately 500 million years ago during the Cambrian period. This period saw the rapid diversification of life forms in the oceans, including the development of early fish species.
Who was the first life on eath?
The first life on Earth were single-celled organisms such as bacteria that appeared around 3.5 billion years ago. These simple organisms evolved over time into more complex forms of life.

When did the first life forms appear on Earth?
Scientists think that the first life forms appeared on Earth about 3.6 billion years ago. These were simple cells that eventually evolved into the abundance of life we see today.
Were the any major events in the precambrain period?
During the Precambrian period, Earth's atmosphere and oceans were forming, and the first simple life forms like single-celled organisms appeared. There were no major events like the complex life forms and multicellular organisms evolved later during the Paleozoic era.
Contrast the major forms of life that appeared during the four eras of earth history?
During the Precambrian era, single-celled life forms such as bacteria and archaea dominated. In the Paleozoic era, multicellular life forms including invertebrates like trilobites and early fish emerged. The Mesozoic era saw the rise of dinosaurs and the first birds and mammals. Finally, during the Cenozoic era, modern mammals, birds, and flowering plants became abundant.
What life forms were in the proterozoic eon?
There were no life forms as we know them during the Proterozoic period. With oxygen just then being accumulated in the earth's atmosphere, it brought the first advanced single-celled eukaryotes and multi-cellular life forms.

What were the life forms in the precambrian era?
The Precambrian Era was the first emergence of complex, multicellular life forms on earth. Jellyfish and segmented worms were discovered to have lived during this time.

What era did bacteria first appear on earth?
Bacteria are believed to have first appeared on Earth over 3.5 billion years ago during the Archean Eon. These simple single-celled organisms are among the earliest forms of life on our planet.
When did life first evolve on earth?
It is generally believed that life first appeared sometime around 3.8 billion years ago. The first life forms were simple, single celled organisms with no nucleus. The first photosynthetic organisms were cyanobacteria, and the evolved about 3 billion years ago. Life first began a rapid amount of diversification during the Cambrian, a little more than 500 million years ago.
