What was the name of the thing that first lived on earth?

Answer 1

These biota are known as prokaryotes, and modern thought divides them into Archaea, and bacteria. They lack a nucleus and DNA, and are resistant to a wide range of environments.

They precede algae in evolution.

That's a hard questionThe above answer addresses the question "What are the most primitive/simple living things on earth today?". We can't know what life was on earth 4 billion years ago. But whatever the first lifeform was, it must have been far simpler than anything we see today - so simple, in fact, that it couldn't possibly survive today. Basically, if you want to have any hope of guessing what it was like, you need to abandon all preconceptions about cells and possibly DNA. You also need to abandon the idea that there's a big gap between life and non-life. So even if we all knew exactly what happened back then, we might not agree on which step was the "first living thing". PossibilitiesBefore life appeared on earth, the organic material which now forms part of all living things would have existed mostly as simple organic compounds in the sea. The replication of DNA (or something equivalent) could have been catalysed by changes in temperature or concentration. For example, a solution containing single-stranded DNA and free DNA bases, when frozen, could have formed double-stranded DNA; thawing could then have split the strands apart to form single strands again. Or maybe the same effect could have been achieved in small puddles which were sometimes dried up (creating double strands) and made wet again (splitting the strands apart). There may have been minerals which catalysed these reactions.

Answer 2

some people think its dinosaurs but insects were first they probably got killed by the tidal wave because the Triassic era was covered with water in the Atlantic, pacific and Indian ocean dragonflies and water beetles next dinosaurs then ice age.

Answer 3

In Biology, the ancestor of all existing life is called LUCA - the Last Universal Common Ancestor. LUCA were probably similar to present-day archaea. There may have been even earlier living things that did not survive into the present because they were driven out of existence by competition.

Answer 5

the first creature on earth were: trilobites, giant sea scorpions, and huge sea squids (PS: they all lived BEFORE the dinosaurs.)

Answer 6

Bacteria are believed to be the first life form on Earth.

Answer 7
