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.

When did the earliest life evolve?
The first life apeared on earth some time around 4.4 billion years ago.
What was the very first plant on earth called?
No one knows what was the first plant to evolve from single celled life forms, so the first one likely does not have a name.
Where did life on earth evolve from?
Probably photosynthetic multicellular protists, such as Rhodophyta and Chlorophyta.
The first cells to evolve in primitive earth were most likely members of the domain?
The first cells to evolve in primitive Earth were most likely members of the domain Bacteria. These cells were prokaryotic, lacking a true nucleus, and could survive in extreme environments. Their simple structure and ability to adapt to various conditions allowed them to thrive and serve as the foundation for life on Earth.
What were the first forms of life?
The first forms of life on Earth were likely single-celled microorganisms, such as bacteria and archaea. These simple organisms are thought to have appeared around 3.5 to 3.8 billion years ago in early Earth's oceans.
Why has life become possible only on the Earth?
Life formed on earth because the conditions were right for life to begin and evolve. While some think that life (as we know it) is only possible on our earth, others think that somewhere, in the vastness of the Universe, life on a similar planet to earth must exist.
Does natural selection deal with only plants?
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
What factor made evolution moves very slowly for the first two billion years of life on earth?
Anaerobic metabolisms and asexual reproduction
What was the first type of true cells to form on earth was?
Prokaryotic cells were the first type of true cells to form on Earth. These cells lacked a defined nucleus and other membrane-bound organelles, but were able to carry out essential functions of life.
What were the first type of creatures on Earth insect mammals birds or fish?
The answer to this question is fish as fishes were the first invertbrates to evolve.
Does earth shape life or life shapes earth?
Life has shaped Earth through processes such as photosynthesis, which has transformed the atmosphere, while also influencing the climate and geography of the planet. At the same time, Earth's physical and chemical environment has provided the conditions necessary for life to evolve and thrive. Both life and Earth have had an interdependent relationship, each influencing the other in various ways.
Where did life evolve on Earth?
It evolved in the oceans....there probably is a specific ocean or part of an ocean but that would be impossible to locate.
