Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution.

A team led by UCLA palaeobiologist William Schopf discovered microorganisms in mud off the South American coast.

"It seems astounding that life has not evolved for more than 2 billion years-nearly half the history of the Earth. These microorganisms are well-adapted to their simple, very stable physical and biological environment," Schopf said in The Daily Mail.

The microorganisms are identical to fossils found in Western Australia, and confirm that organisms will not change biologically if there is no change in their physical environment, a central belief in Darwin's theory. Scientists analyzed the fossils using methods that made three dimensional images of rocks. The research, published in the Proceedings of the National Academy of Science, was conducted through fossil analyzation methods that made 3-D renderings of rocks.

"If they were in an environment that did not change but they nevertheless evolved, that would have shown that our understanding of Darwinian evolution was seriously flawed. The rule of biology is not to evolve unless the physical or biological environment changes, which is consistent with Darwin," Schopf added.
