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.
Where on Earth did the first life forms evolve?
the first lifeforms probably some sort of algae evolved in the sea millions of 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.
What was the first type of true cells to form on earth was?
The first true cells were prokaryotic cells. These were simple life-forms that didn't have a nucleus. The next to evolve were eukaryotic cells which do have a nucleus.
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.
The first cells to evolve in primitive earth were most likely members of the domain?
Bacteria
The time in which life first evolved on Earth was the?
eff the time in wich life first evolved on earth!!
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 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.
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.
