Fossils point to life on Earth 4 billion years ago

PARIS - Tiny fossils that scientists say are the oldest ever found offer evidence of life on Earth 3.8 to 4.3 billion years ago, when our planet was still in its infancy, researchers reported on Wednesday.

Even at the more primitive end of the spectrum, "the microfossils we discovered are about 300 million years older" than any runners-up, said Dominic Papineau, a professor at University College London, who made the discovery.

Dating puts the fossils "within a few hundred million years" of the formation of the solar system, he said.
