In what form the 1st living creature existed in the world?

Question

how does it evolves?

Answer 1

It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. Some crawled from the seas and took residence on land, perhaps to escape predators in the ocean. A cascading chain of new and increasingly differentiated forms of life appeared all over the planet, only to be virtually annihilated by an unexplained mass extinction. It would be the first of several mass extinctions in Earth's history.

Answer 2

As a single celled organism? Like a paramecium... or a bacteria or something... something that's really simple.

Answer 3

Shapeless embryo.They were in an embryon'ic form=rudimentary.

Answer 4

The 'first' living organism, single-celled, was part of a larger organism called a colony, of similar single-celled organisms. They developed simultaneously, not uniquely.

Answer 5

a unknown one celled organism which evolves to a multi celled organism and evolves up to the present day

Answer 6

well the thoery today is that, simple one celled organisms were brought here on meteors, or the other, which has been done in a lab, is that the simple molecules of amonia, carbon, nitrogen, when charged by lightning could actually form the basic amino acids for life and from make up a one celled organism.  as time goes one celled organisms get together to create multiple celled organisms, the one celled organism could be what you call the first, or it could be those multiple celled ones, or from there you may consider the first algea like life to be the first.
