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
Where is the first living organism on earth in air or land water atmosphere?
The first living organisms on earth were a type of aquatic photosynthetic bacteria called cyanobacteria (blue-green algae). These organisms formed structures called stromatolites. These organisms did not become extinct and still exist in both salt and fresh water environments.
The first eukaryotic organisms on earth were?

What came first oxygen or life?
Life came first. The oxygen in Earth's atmosphere is a product of living organisms carrying out photosynthesis.
Are there living organisms in pond water?
yes, there are living organisms first known as animalcules.
What thing existed on earth first?
The first living things on Earth, single-celled micro-organisms lacking a cell nucleus or cell membrane and known as prokaryotes first appeared on Earth almost four billion years ago.
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.
Which type of organism most likely evolved first?
microbes were the first inhabitants of earth. they are single-celled organisms; bacteria, fungi and protozoa. (: and Simple prokaryotes
Was oxygen on Earth before or after life on Earth?
Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.
What life form was on earth first?
Earliest life form is microbe, a unicellular organism. First bacteria can dated back to 3.4 billion year ago. Emergance and true cut point from being a replicating molecules to a living cells is still unknown.
