Most evolutionary biologists theorize that the first living organisms were single-celled prokariotes similar to currently existing bacteria.
The distinction between proto-biotic and true life is a difficult one, so while there were self-replicating amino acid chains, the first life would have been a distinct cell that divided in an aqueous (watery) environment.

The first cells to evolve in primitive earth were most likely members of the domain?
Bacteria
Why did the first cell not evolve on earth?
So...one theory is that cells came to Earth from comets or from aliens seeding the planet...the operative term is theory.
When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
What was the first type of bacteria on earth?
the first type of cells on the early earth were prokaryote cells.
What are the oldest cells on earth?
The first cells on earth were likely prokaryotic. This is because the prokaryotic cells are not complex like eukaryotic cells.
The first cells to evolve in primitive earth were most likely members of the domain?
Bacteria
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.
Which two types of cells do scientist think was the first to evolve?
Prokaryotic cells were the first to evolve and then later Eukariotic cells came along.

Why do scientists think the first living cells to spear on earth were pobably anaerobic heterotrophs?
there was no oxygen in Earth's early atmosphere.
When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
What are three major scientific inferences about the first living cells on earth?
photosynthesis, chemosynthesis, and aerobic respiration1. Little or no oxygen was present on early Earth; 2. Oldest fossils are thought to be cells of living prokaryotes 3. the first cells might have developed in an enviorment filled wit molecules for food
How did mankind begin if we evolved from animals Where did living cells first come from?
Nobody has the exact answer to how mankind began. It is thought that the first living cells came about due to the combination of enzymes in the sea or from a meteorite falling to earth. Eventually humans evolved from these cells and animals.
What is the fourth component of cell theory?
The four parts of the cell theory are the following:All living things are composed of one or more cells.All cells are reproduced from existing cells.All of an organism's life functions occur within cells.All cells have DNA, or hereditary material.
What group of organisms alive today are most similar to the first cells on earth?
bacteria is still around and it was one of the first living organisms
What was the first type of bacteria on earth?
the first type of cells on the early earth were prokaryote cells.
Were the first seen cells living or nonliving?
The first seen cells were non-living and they were found by Robert Hooke in a sample of cork.
