A glimpse on the origin of life on the Earth, enables us to conjure up the first species. It must be slightly more advanced than a coacervate with RNA as the genetic material, having a capacity to duplicate. This form must be simpler than bacterium and much simpler than Amoeba.The question of naming would arise once we became sure of the form.

Earth is the name of this planet, therefore a proper noun, so it gets a capital first letter. As should the first letter in the beginning of your question.
Nobody really knows the first species of Earth. The was a progression from singular celled life forms to multi-cellular forms. So it would have been something very simple. It could still be existing, we wont know until we figure out just how life got started on Earth.

Im sure it wasnt cellular life, i think it was more like a virus, only that they could self-replicate. The first "life form" as we define life must have been a protein coumpound with a RNA nucleus. Later in the development of life Cellular organisms would rise
To the guy below me: According to the bible, Adam and Eve were created after the rest of the animals, so at least know the "theory" you are talking about.

The name of the first living species born on Earth was, surprisingly, Hubert! Who knows why, and, one has to wonder, if Hubert was the first, who named him? Sounds like a question for the philosophers to me!

the first organism to be reported on this Earth was almost 4 - 3.5billion yrs ago...
during that time planet Earth was nothing but surrounded by the soup of organic substances such as amino acids, hydrocarbons etc.
these gradually coalesced to form micelles as defined by Oparin...
this then gave rise to an organism having its first genetic material as RNA...
yes the first reported genetic material on Earth to be thought by the scientists is RNA....
n probably the first organisms were viruses..
which were followed by Archaebacteria when RNA transferred its genetic nature to DNA...
so first DNA holders were Archaebacteria...
these Archaebacteria gave rise to Eubacteria...
now in eukaryotes what u find as mitochondria n plastids these are probably the symbiotic Archaebacteria....
so Amoeba cant be the first organism on this Earth....
as Amoeba itself is an Eukaryotic cell....
there is a large misconception i hv noticed here......

People are saying amoeba because thats the only single celled animal they know. It would really be more prokaryotic. (closer to a basic bacteria than an amoeba type.)

Amoeba

in evolutionary terms, it would be the last universal common ancestor (LUCA). identity is still debated, as with much of evolution anyway. but if it does exist it would be a prokaryote.

well the scientists believe that the first specie appeared on the earth is ameoba.....and they put various assumptions in favour of this
But from Islamic point of view...teh first specie appeared on the earth is human himself ( Adam )
the Adam is created by the God in heavens and then sent to the earth as his first ever messenger along with his wife Eve.....

it can be amoeba. but i think it was some other micro-organism or maybe coackroach type insect, you know.
